Fish, Sharks & Rays (plus Sea Turtles & Whales)

Chordata

Description

Chordates are the big, familiar swimmers divers often spot—everything from sleek reef fish to cruising sharks and rays. Depending on where you dive, you might also see larger chordates like sea turtles gliding through the water or even whales far offshore. Many have streamlined bodies and strong swimming abilities, making them some of the most noticeable animals underwater.
