Identify Sea Creatures

14 questions · Nature

A dive through the oceans: recognise sea creatures like the dolphin, shark, whale, octopus, jellyfish, starfish, seahorse, lobster, crab, ray, sea turtle, clownfish, sea urchin and sea otter. Good to know: Dolphins are highly intelligent marine mammals that hunt in groups. They communicate with clicks and whistles. Sharks are cartilaginous fish and among the oldest predators of the seas. Some species must keep swimming to breathe. Whales are the largest animals on Earth; the blue whale is the biggest of all. They breathe through a blowhole on the head. The octopus has eight arms and is considered very clever. It can change colour and shape to camouflage. Jellyfish are over 95% water and drift with the current. Their tentacles can sting. Starfish usually have five arms and can regrow lost ones. They have neither brain nor blood. In seahorses, the male carries the young in a belly pouch. It swims upright and very slowly. The lobster is a crustacean with strong claws and a shell. Alive it is bluish, only turning red when cooked.
