Fish come in thousands of shapes and sizes with amazing adaptations to suit a large variety of marine habitats. They have bony skeletons, a scaly skin, a swim bladder, fins and fused jaws. They use gills to breathe oxygen from the water.

Fish have many ways to find their prey of plants or animals like sight, hearing, lights, electrical currents or detection of movement.

But the ocean is full of predators so fish also have many ways to protect themselves such as hiding, venomous spines, methods to frighten others off, camouflage, schooling or by forming partnerships with other plants and animals.
