Zebra Shark

The Zebra Shark

The zebra shark is know for its beautiful markings. There are no attacks on humans by a zebra shark on record.

Identification:
The easiest way to identify a zebra shark is by its unique markings. When it is young it has striped markings (hence the name zebra shark). As they get older, the stripes break into spots. Sometimes the spots will make the outline of the stripes, such as in the picture above. The coloration in juveniles is dark brown with tan or pale yellow stripes. Adult coloration is tan to pale yellow with black to dark brown spots. The zebra shark has 5 gills on each side. It has a broad elongated upper lobe of the caudal fin, and almost no lower lobe. It has small eyes and a small mouth with barbels on both sides of its mouth.
