Like humans, whales like to sing and talk. The sounds are so loud that they can be heard from many miles away. They hunt together and that means they like to work together to get things done.
Squids are said to be among some of the most intelligent invertebrates (no backbone) in existence. They are usually very curious about their environment. They invent new tools and games to stop being bored.
Dolphins have a brain that is second in intelligence to humans. Bottlenose dolphins prove to be aware of themselves by easily recognizing their images in the mirror. Dolphins think before acting. They seem to know that children need more patience than adults and are gentler towards them.
Dolphins are very social creatures. This means they want to be with other dolphins.. They do recognize their moms and their leaders. Moms and leaders get extra respect.
