My favourite sea creature is Otter. Dolphins are very clever. An Octopus is very ugly. When its enemies come close, it squirts out some inky liquid. Blue Whale are the largest mammal on earth. When Blue whale comes upto the surface,they breathed out air so hard that we see water.Penguins are cute. The fastest swimmers are the sailfish. They attack fishes by stunning them with their dorsal fins. And then eat the fish. I love sea creatures.
