doh.. why would there be such a question as to how many endangered mammals are in the sea when not all creatures in the sea have been discovered yet!
The blue whale and the pink river dolphin.

Extinct Steller's Sea Cow Bhaji River Dolphin Endangered Sea Otter Manatee
Some sea creatures have ansetors of dinosaurs
Extinct creatures are gone, they are not endangered.
If you mean, "are all under water creatures, sea creatures?" then no. The term SEA is for the ocean and there also can be creatures in freshwater. Also some creatures that live in water such as some snakes and sea turtles come out of the water every so often, so they are no total sea/water creatures. Fish are underwater creatures though.
Since they are mythological creatures the answer could go either way really!
both because some sea creatures eat others. unlike cuttlefish they try to eat eachother.i hope this answers your question.
it is really important because it has the most endangered species of fish and sea creatures there
No furtunately the hippo is not endangered they are magnificent creatures!
