What belongs in this list?
Fish are aquatic vertebrates that usually breathe with gills. The broad group includes jawless fish, sharks and rays, and the enormous diversity of bony fish.
Shapes built for water
Streamlined hunters, flattened rays, deep-bodied reef fish, inflated defenders, and drifting camouflage specialists move in very different ways.
Fish, not every sea animal
Whales, dolphins, sea turtles, penguins, octopuses, and jellyfish live around water but belong to other animal groups.
