Adults and large juveniles frequent coral reefs, rubble, and sandy areas. There are unsubstantiated reports of this species from fresh water in the Philippines Zebra sharks Sometimes cross oceanic waters to reach isolated seamounts. Movements of up to 140 km (87 mi) have been recorded for shark However the individual, genetic data indicates there is little exchange That the between Populations of zebra sharks, even if Their ranges are contiguous The zebra shark has a cylindrical body with a large, slightly flattened head and a short, blunt snout.
The dorsal midline ridge merges into the first dorsal fin, placed about Halfway along the body and twice the size of the second dorsal fin.

There is an observation of an adult male zebra shark biting the pectoral fin of another adult male and pushing him against the sea floor; the second male was turned on his back, and remained motionless for Several hours. This behavior resembles the pre-copulatory behaviors the between male and female sharks, and in Both cases the biting and holding of the pectoral fin has been speculated to relate to one shark asserting dominance over the other.
