Spinner Dolphin

The Spinner dolphin is another type of dolphin found in the ocean. This species grows to about 4 – 5 feet and weighs about 160 – 170 pounds at full maturity. Like the Spotted dolphin; the color, shape, and size of the Spinner dolphin is determined by the region the dolphin is in. They do have a long, slender beak. The bottom of the beak is white and the top of the beak is black. This species is found in the Tropic of Capricorn and the Tropic of Cancer. The majority of the Spinner dolphins are found in Hawaii. They live in the deep parts of the ocean so they can easily find prey.

Spotted Dolphin

The Spotted dolphin gets its name from the spots that are found on its body. There is no one particular size or color of these dolphins because the color and size of them are different for each region they are in. Basically, the only way to distinguish this species is by its’ spots. They can swim up to 30 miles per hour. These dolphins have now been put on the endangered list due to people killing them for their meat, oil, and skin.

Tucuxi Dolphin

The Tucuxi dolphin is the last of all the different types of dolphins. This species is found to the north and east of South America. The Tucuxi dolphin is found in the ocean, but also found in the Amazon Basin. This species is also known as the Pink dolphin because of the pinkish color on their bellies. Their backs are bluish-gray. Out of all the types of dolphins, this species is known as one of the smallest in the ocean.

White Beaked Dolphin

The White Beaked dolphin is known as the ‘dolphin of speed’ because of its dashing speed through the water. They have a powerful tail and fins that help them propel through the ocean at blazing speeds. They are dark gray to black in color with white bands on their flanks. They grow to be about 8 – 9 feet in length and females are usually a bit smaller in size. They are mostly found in the cool waters of the North Atlantic ocean.

Baiji Dolphin

The Baiji dolphin is known as the “River Dolphin” because it lives in the rivers of China. It is believed that the dolphin appeared about 25 million years ago. These dolphins would reach about 8 feet in length and up to 500 pounds for males and 350 pounds for females. These dolphins are bluish-gray and have a flexible neck with a long snout. Due to propeller strikes, pollution, human catching and other problems, these dolphins were declared extinct as of last year, but it is believed there are still a few left.

Bottlenose Dolphin

The Bottlenose dolphin is one of the prettiest and smartest dolphins in the sea. These are the dolphins you see at Sea World and in movies all the time. They reach 10 – 14 feet in length and grow up to weigh 900 – 1,100 pounds. They are very smart and social animals and are bluish-gray in color.

Black Dolphin

The Black dolphins are also known as the “Chilean Dolphins” because they are located in the coastal waters and river areas of Chile. They grow up to about 5 – 6 feet in length and about 130 – 150 pounds in weight. Out of all the different types of dolphins, this is one of the smallest ones. These dolphins are gray with light color variations on their ventral fin. The Black dolphins dorsal fin and flippers are actually round in shape.

Hector Dolphin

The Hector dolphin is one of the smallest out of all the types of dolphins. If you get the pleasure of spotting one of these, you are very lucky. This particular species is very rare and hardly ever seen. It is one of the smallest only reaching about 3 feet when fully grown. The females do tend to be longer than the males though. These dolphins are brown, gray, black, and white and have markings that are black and white. The Hector dolphin is often called a ‘Torpedo’ because of the shape of its body. It likes to live in muddy swallow water and is found on the coast of New Zealand. The New Zealand coast is actually the only place in the world you can find the Hector dolphin.

Clymene Dolphin

There are many different types of dolphins as you can see and some are similar to others. The Clymene dolphin is very similar to the Spinner dolphin. It is very small in size but has a rather long beak. The dolphin has a white belly with dark gray lines on its’ beaks. These dolphins are deep diving dolphins, meaning they are hardly ever seen at the surface of the water. They are anywhere from 520 feet to 16,400 feet below the surface. They are found in the Atlantic ocean in tropical and sub-tropical waters.

Communication Techniques

One of the most interesting Bottlenose dolphin facts is the communication techniques they use. Each Bottlenose dolphin has their own unique whistle, just like we have our own voices. So, when a dolphin whistles, the other dolphins will know who it is. They also click their teeth to communicate and use body movements to communicate. For instance, if you have ever seen a Bottlenose dolphin slap its fin or tail on top of the water, or jump out of the water and land on its side, then you have witnessed them communicating. They have many ways of communicating with one another.

Reproduction Facts

The reproduction of Bottlenose dolphins is very interesting. For starters, they normally start reproducing at the age of 6. They mate all year long and only get pregnant once every two to three years. Once a Bottlenose dolphin becomes pregnant, they carry their young for 12 months before giving birth. Bottlenose dolphins deliver all year long, but spring and summer is the most popular time of year. When a calf is born, they are born tail first. That way they won’t drown while being delivered. Once the calf is fully delivered, the momma will push the calf to the surface for their first breath to be taken.

Raising Their Young

Bottlenose dolphin facts are pretty interesting when it comes to giving birth and raising their young. As mentioned above, a mother dolphin will carry her young for 12 months before it is born. Once the baby is born, there will be other female dolphins around her to help her deliver the baby. It’s kind of like the doctors and nurses that help us, the other females will help her. A baby Bottlenose dolphin is called a calf. The calf will remain with the momma up to the age of 6. Once the dolphin reaches the age of 6, the females will begin reproducing. Male dolphins do not help the females raise the babies.

Dolphin Behavior

One of the most amazing facts about dolphins is their sociability. They are real social and most of the time are not afraid to approach you. Sometimes when people are diving, or out on a tour to see dolphins, they will come right up to you and allow you to rub them. Always be careful though. They have been known to turn aggressive in a split second. So, never let your guard down. Bottlenose dolphins are very playful and play among each other all day. The dolphins will stay in a pod of about 12 dolphins and chase each other, roll over each other, surf the waves, and more to play.

Dolphin Suicide – ‘Beaching’

I’m sure you have heard the news about dolphins beaching themselves, or you might have actually witnessed this. The truth is, dolphins beach themselves quite often. Beaching is when they go up on the shore and lay there and die. It is basically suicide. The reason a dolphin ‘beaches’ themselves is usually due to sickness. Many dolphins encounter pneumonia which is the leading cause of sickness. If a dolphin is sick and can’t get better, they will leave their pod and commit suicide.

Are Bottlenose Dolphins Endangered?

Are Bottlenose dolphins endangered? Well, the answer to that question is yes and no. Yes, because in a few parts of the world they are endangered due to the fact that many people kill them and eat them. No, because in the majority of the world, they aren’t.

What is Harming the Dolphins?

The Bottlenose dolphin threats list goes on and on. Some of the threats come from commercial fisherman, where other threats come from whales that eat the dolphins. You also have those who fish for the dolphins, catch them and sell them for the meat. Though dolphins are amazingly smart, there are some things they just can’t avoid.

Sea Life Prey

Many forms of sea life feed on dolphins. Sometimes the Bottlenose dolphins just can’t escape the raft of a hungry sea enemy. Some of the predators include sharks and Killer whales. Many sharks like the Great White shark, Tiger shark, Bull shark, and the Dusky shark will come after the dolphins and eat them. Stingrays are also known as predators in the Bottlenose dolphin world. However, the stingray does not eat the dolphin, the dolphin dies from wounds inflicted by the Stingrays poison. Most people think only Killer whales kill dolphins, but as you can see, that is not true at all.

Human Threats

Humans play a big part in adding threats to these dolphins. In some countries, as sad as it is to say, people will catch the dolphins on a line or in a net and sell them. They kill the dolphins once they are caught and sell them to profit from the meat or keep them for themselves to eat. It is illegal in some countries, but not all countries have outlawed it. Even in countries that its illegal in, people still continue to do it.

Another threat includes humans throwing out nets to catch fish, shrimp and other sea life and accidentally getting dolphins tangled up. The main reason a dolphin will get tangled in a net is for the food. They will see all of this food swimming around in a confined trapped area and they will think, “Oh boy, buffet!”. Once they proceed to prey on the trapped fish, they get caught in the net and die.

How to Save a Beached Dolphin

Many Bottlenose dolphins become stranded on shore. This happens for a few reasons, but no matter the reason, you can help a dolphin if you ever encounter one out of the water and needing help. Get someone other than you to call 911 and they can transfer you to the appropriate officials. Tell them you have an emergency and what is going on. In the meantime, you will need to find something to put water in and keep pouring the water on the dolphin. That will help the dolphin breathe long enough for someone to come haul it back into the ocean.

Camouflage Techniques

The truth is, Bottlenose dolphins don’t really camouflage themselves to avoid prey, but due to the color of their body, they are able to hide a lot easier from prey than other sea life. However, they do use a couple of methods to protect themselves from prey in the ocean. One of the methods they use is when they take their nose and ram into a prey’s stomach, like a shark for instance. They also stay in pods where they can help fight off prey. Also, another thing that helps them fend off prey is jumping. Jumping allows them to startle their enemies long enough to get away.

Swimming Techniques

As you already know, Bottlenose dolphins swim their whole life. They play, eat, give birth, and do everything while swimming. Dolphins have two types of swimming they do; high-speed swimming and slow-speed swimming. They mostly swim slowly, but they have times when they do high-speed swimming as well. Normally, they swim at speeds of about 4 to 8 mph. However, when they reach their high speeds, they swim at about 20 mph. This high-speed swimming only lasts for a few seconds at a time.

Respiration Techniques

You probably already know that a dolphin has a blowhole on the top of their body. However, you may not know all of the Bottlenose dolphin facts on that blowhole. The blowhole is used for the dolphin to breathe. It has a muscular-flap over it that opens when the dolphin comes up for air. It then is tightly sealed when the dolphin is under water so the water doesn’t get inside of it. The dolphins can hold their breath up to 15 minutes at a time, therefore they can stay under water for 15 minutes before coming up for air.

Sleeping Techniques

Adaptations of Bottlenose dolphins are pretty amazing, especially when it comes to them sleeping. Did you know a dolphin actually sleeps? When people think of dolphins swimming, they don’t think about them sleeping. Well, they do sleep. Actually, 33% of their day is spent sleeping. They need their rest just like we do. However, sleep only occurs in one brain hemisphere at a time.

How Far Can a Bottlenose Dolphin Dive?

A Bottlenose dolphin can dive quite deep, but rarely do. They can dive more than 150 feet deep, but usually stay within 10 feet from the top of the water due to them needing to come up for air every 15 minutes.

What Do Bottlenose Dolphins Eat?

Bottlenose dolphins feed on things such as fish, squid, shrimp, and other small sea life. They sometimes will follow a fishing boat dragging nets of fish in hopes of snagging some of them for lunch. However, one of the sad Bottlenose dolphin facts regarding this eating technique is they sometimes get caught in these nets and die.

How do They Help Each Other Find Food?

Due the the fact that Bottlenose dolphins help one another find food, they are able to eat quite a bit. That’s why these mammals are known as social beings; they help one another. The pod of dolphins will gather around and run a large school of fish to the middle of the school. The fish will then all bunch together and the dolphins go in for the kill, or what some call; buffet. In all of the Bottlenose dolphin facts, this is one of the most intriguing thing about these mammals. They truly work together.

Do they Fight Over Food?

When it comes to the Bottlenose dolphins diet, they must consume quite a large amount to live. So, do they fight over their food? Well, not normally. Usually, they just work together to get food. There are some instances when food is so slim that they will tussle a little over the food, but for the most part, the answer to that question is no.

Do they Drink Sea Water?

As tempting as it may be for a dolphin to drink sea water, they don’t. If they were to drink sea water, they would need more water than the sea to wash the salt out. Dolphins get their water intake from the food they eat like squid and fish. They also get water when they burn fat. They are built to not need water, so the little bit they get from their food and the fat they burn is plenty enough.

How Much Food do They Need to Live?

How much food they require to stay alive and be healthy will definitely depend on the age and size of the dolphin. However, a generic answer to that question is up to 30 pounds of food a day. 30 Pounds!! That seems like a lot of food to us, but as much swimming as a dolphin does, it’s not much to them because they are constantly burning fat.

So… Where do they live?

That’s a really good question and the answer is simple; all over the world. Bottlenose dolphins prefer warm tropical waters though. They stay in waters that range from 50 to 90 degrees. They travel long distances and have been spotted in many parts of the world. It is easy to spot Bottlenose dolphins in the Pacific and Atlantic oceans, and they have also been spotted in the Mediterranean and Black Sea.

What is a Bottlenose Dolphins Habitat Like?

The Bottlenose dolphin habitat is really unique as they live in a variety of different habitats. The habitats depend on the location of the dolphin. For example, in the Atlantic, some dolphins are found as close as 1 or 2 miles from shore. In other areas, the dolphins are found more than 25 miles out to sea. It all depends on the area and the dolphin. Normally, these dolphins will swim together in groups known as pods.

What is the Density of the Water They Live In?

This is another interesting Bottlenose dolphin fact that changes and never stays the same. The density of the water depends on the dolphin. Some things you would need to factor in is if the dolphin is diving for food, or just swimming along. If they are diving for food, then the density of the water will become thicker. If they are just swimming along and are near the top of the water, the density is pretty thin. So, the density of the water usually depends on the area, what time of day it is and what the dolphin is doing.

What is the Most Popular Habitat for Bottlenose Dolphins?

Some areas are more popular for spotting the Bottlenose dolphins than others. Some of these areas include anywhere in the Atlantic and Pacific oceans where the water is warm. Florida is a really good place to see these beautiful animals in their natural habitat.

As you can see, the Bottlenose dolphins live in many areas and prefer the warm tropical areas of the sea. These mammals also have different habitats depending on their location, so it is hard to pinpoint one particular habitat.
