DOLPHINS BELONG IN THE WILD.
Facts about dolphins.
Dolphins are part of the cetacean family.
There are 32 species of dolphin and 4 species of river dolphin.
Dolphins eat fish, squid and crustaceans.
An adult dolphin eats around 33lbs of fish a day.
Dolphins are known for their playful behaviours and are highly intelligent.
Killer whales and pilot whales are also part of the dolphin family.
Dolphins are known to be very social creatures. Living, hunting and playing together in groups called pods.
Large pods of around 1,000 dolphins or more are known as superpods
Dolphin gestation takes around 9 to 17 months depending on species.
Calves are known to stay with their mothers from 3 to 8 years.
Calves nurse from their mothers for approximately 2 years.
Dolphins have good eyesight both in and out of water.
The lenses and the cornea in a dolphin’s eyes naturally auto-correct for the difference in the refraction of light underwater and above the surface.
Dolphins have larger brains than humans.
Echolocation allows dolphins to “see” by interpreting the echoes of sound waves that bounce off of objects near them in the water.
To echolocate objects nearby, dolphins produce high frequency clicks.
These sound waves are bounced back to the dolphin after coming into contact with an object. This allows them to identify the object’s location, shape and size.
The amount of time for the sound wave to bounce back allows dolphins to determine their distance from the object.
