Sea anenomes, sea cucumber, sea lettuce, seagull, sealion. that's all. Don't forget about the sea slug. Everybody forgets that one, just cos it's a slug and a bit ugly. And the sea horse, now they are cute. Bit boring though, they just seem to hang about next to a bit of seaweed (note that seaweed is not an animal but a plant. Just in case you got a bit confused there).

Sea slugs are marine invertebrates known for their vibrant colors and unique shapes. They are often hermaphrodites, meaning they have both male and female reproductive organs. Some species of sea slugs are capable of photosynthesis due to the presence of chloroplasts in their tissues. They can be found in various marine habitats worldwide, from shallow waters to the deep sea.
