Manta ray

Manta rays are never still, as they must keep gliding through the water at all times. Their bodies have no bones in the usual sense. Instead, the skeleton is built from cartilage, a softer and more flexible material, which lets the animal's wide pectoral fins flap and curl with ease.

This book introduces readers to these large sea creatures and their life beneath the waves. It is part of the Giants of the Ocean series.
