Appearance


Dolphins are beautiful. They are shiny when they jump out of the water if it is sunny.
Dolphins have dorsal fins on their backs like most fish do. They have 2 flippers on their side and a tail called a fluke. This helps them swim really fast. Dolphins are 1.2m to 9 meters long. Their bodies are long and narrow and they have a dark back and and a light coloured belly. Their ears are right beside their eyes and they are holes.

Dolphins whack fish with there tails to kill or knock them out then eat them. Dolphins swallow fish head frist and do not eat rotten fish. Dolphins fatten up when there is lots of food.

Offspring

Young dolphins are called calves. They give birth every two to three years. Dolphins only have one calf at a time. They have to be born in water, or they will die. The calf is born head first. Babies that are born tail first may die before they are free from their mommy. New born babies can see, hear and swim. Calves drink milk from their mom for three years.

Adaptations

Dolphins have long steam lined bodies so they can swim around faster. The dolphins have cone shaped teeth to hold the fish they eat. They make sound and then it bounces back to them, so they know what is around them. This is called echolocation. They use echolocation to find their food and to swim away from their predators.
