Membrawhales are a species of giant fish that feed on plankton and krill using the sifting fibers on its fins. They have lost the ability to digest poisons. They have no known predators due to there size compared to others. The young are taken care of by their mothers and will become independent when they are old enough. Despite their large heads, they are pretty dumb. They don't travel in groups and sift krill into their mouth all day.
