Rays are related to sharks, because they don’t have bones - they have cartilage, like our ears or nose. They glide through the water, like birds fly in the air. They eat clams, shrimp, and even crabs. This one is eating small shrimp in the water which were attracted to boat lights at night. It swam in circles around the light, as it ate a late night dinner. It can also dig in the ground for food. It uses its strong nose and fins, to reach way down, to the clams and worms living in the bottom.
