Weaselwhale

Weaselwhales are a group of fully aquatic marine mustelids that are descended from a group of Ekorus that adapted to life in the sea. They can reach 11 inches long to about 23 inches long, depending on a species. They are very similar to toothed whales, but unlike whales, they lack dorsal fins or front flippers, due to smaller sizes and extra flexibility, so there's no need to have dorsal fins or flippers. They mainly feed on soft coral, jellyfishes, anemone, shrimps, lobsters, crabs, small fish, and eggs washed into the sea. They have tolerance to venom and poison of other marine animals, so that explains why they prey on anemones, anemones, jellyfishes, and some small poisonous and venomous fish. Unlike whales, weaselwhales don't beach completely as they can squiggle and try to get back into the sea, in a similar fashion to fish. They usually beach themselves by accident if they're hunting for baby sea turtles or eggs of sea turtles or birds, but sometimes if they are trying to hunt the fish that swim very close to the land. Most weaselwhale species are not threatened to extinction as they tolerate climate changes, pollution, and overfishing, so it gives many weaselwhale species chances of survival in the future, but few species, however, such as the arctic weaselwhale is vulnerable to global warming and overfishing.
