Let’s learn interesting facts about dolphins! There are more than 40 species of dolphins on earth. Some are small, and some are big. Most live in the ocean, but some live in rivers.we are going to talk about today.
Even though they live in the water, dolphins are mammals! That means they are warm-blooded, they feed their babies milk. They must come to the surface of the water to breathe air.
Dolphins breathe air through a hole on the top of their head called a blowhole. When they go underwater, dolphins close their blowhole tight!
You may know that mammals have fur or hair, and even though they do not look very hairy, dolphins are no exception!
Baby dolphins are born with little whiskers on their jaw which fall off soon after they are born and never grow back, leaving them smooth and slippery, which helps them swim 01:19 quickly through the water.
Dolphins are carnivores, using their pointed teeth to catch fish that they swallow whole, but they will also eat squid and crustaceans.
Something amazing about dolphins is the way they find their prey: echolocation! the dolphins will make a special sound which bounces off of objects around them. When the sound waves return to the dolphin, the shape of the echos tells the dolphin what shape and size the object is, as well as how far away it is and how fast it is moving.
Adult bottlenose dolphins can reach lengths of up to 13 feet or 4 meters, and weights of up lbs or 650 kilograms, but an average dolphin only grows to about 8 feet or 2.5 meters and 660 lbs or 300 kilograms.
They can live up to about 40 years and may jump out of the water 20 feet or 6 meters into the air! They live in oceans all around the world, only avoiding the icy waters of the Arctic and Antarctic.
Bottlenose dolphins are gray: dark gray on the top, and light gray on the bottom. This type of coloring is called countershading and helps the dolphins camouflage themselves against predators trying to see them from above or below.
Dolphins like to live in groups and that group is called “pods”, which usually have somewhere between 10 and 15 members, but dolphin pods have been spotted with more than 1,000 dolphins together!
Dolphins are very intelligent and have a special relationship with humans. Sometimes dolphins will help human divers who are injured by pushing them to the surface, which is something they will do for other dolphins that are hurt.
Dolphins will also sometimes help fishermen by driving fish towards them, helping the fishermen to catch more fish than they would alone. Once dolphins even protected swimmers from a great white shark by swimming around them until they could get to shore.
Dolphins kept in captivity may be trained to do tricks or important work, like locating underwater mines. More than half a million bottlenose dolphins swim in Earth’s oceans and fortunately, they are not endangered!
If we want to keep it that way, it is important to help protect our oceans and the creatures that live in them. Help conserve water, pick up litter and trash that could someday get washed into the ocean, and be sure to only buy tuna that is caught using methods that are safe for dolphins.
I hope you enjoyed learning about dolphins today.

Dolphins are extremely intelligent mammals which are part of the family that includes pilot whales and Orcas. They are found around the world and in shallow waters around the continental shelves.
Dolphins are carnivores that mainly eat squid and crustaceans. generally grey in color with darker backs and lighter undersides. They use echolocation to help them hunt and navigate the oceans. They listen for echoes and their senses help to guide them around.
There are very agile creatures and are known for their playful behavior. In order to view their surroundings, they will spy-hop. Which is where they will rise up vertically out of the water. It is thought that dolphins look to conserve their energy by swimming alongside ships, a practice known as bow riding.
They are social animals and will live in groups together often synchronizing their movements with one another. By being in groups, they can hunt more effectively and protect one another.
In order that they can sleep half of a dolphins brain is asleep. Whilst the other half stays awake so they can continue to breathe and stop from drowning. Dolphins tend to mate throughout the year but there are seasonal peaks in spring and fall.
Depending on the species, they will have a gestation period of between 9 and 17 months and by the time. They are ready to give birth they will distance themselves from the rest of the pod. And travel towards the surface and give birth.
Dolphins will usually give birth to one calf a year. Twins have been evidenced but are rare in the Dolphin world as soon as a calf is born it will be taken to the surface so it can breathe. The Dolphin will nurse the calf for between 11 months to 2 years. Once it has been nursed it will stay with its mother for anything between 3 and 8 years old.
