Zebra Bullhead Shark facts are all about their habitat, behavior, and feeding habits.

The zebra bullhead shark (Heterodontus zebra) is a common but little-known bottom shark and one of the nine known living species of bullhead sharks of the world. They are members of the family Heterodontidae like the Port Jackson and the horn shark.

These oviparous sharks are known for their distinctive black/brown zebra-like stripes over a white background and, their blunt snout, square head, and stout body.

These are harmless and nocturnal sharks whose distribution normally dwells on the seafloor, usually on continental shelves. They can survive at depths from 164 ft (50 m) to 656 ft (200 m) below the surface of the sea.

They are endemic to the marine waters of the Western Central Pacific, the coast of Australia, and East Asian countries like Korea, Vietnam, China, Japan, and the Islands of Indonesia. Their distribution is towards the south of Wakayama Prefecture and is also known as the Japanese bullhead shark for this reason.

How do they reproduce?

The reproduction of these species of shark is oviparous, unlike other sharks. Eggs are laid in egg cases that are spiral in shape.

Their biology shows that this spiral shape allows the egg cases to be wedged inside rock crevices, which prevents the attack from predators and protects the egg. Females lay two eggs simultaneously, during spring to late summer and this process is performed almost 6-12 times during the spawning season in Japan. The eggs hatch after a year.

Females lay up to two eggs at a time during spring to late summer. It takes around a year for the eggs to hatch and their length range from 0.5 ft-3.9 ft (18 -120 cm.)

During the process of courtship, males clutch the female shark by its pectoral fin and then wrap its body's posterior part beneath her. This position helps the males in the insertion of its clasper inside her cloaca.

What is their conservation status?

Zebra bullhead sharks are listed as the Least Concern on the IUCN Red List of threatened species. These species of fish are not prioritized by fisheries for commercial purposes but are often used as a bycatch during fishing.

Zebra Bullhead Shark Fun Facts

What do zebra bullhead sharks look like?

The body of these shark consists of a stout central body that is cylindrical in shape. It has a blunt snout and a large square-shaped head consisting of two sizeable protruded ridges above each eye.

Spiracles present behind the eyes help them to breathe. These shark species have two dorsal fins which are tall and consist of a prominent internal spine at their origin.

The first origin of the dorsal fin is located approximately at a level with the insertion of the pectoral fin. Similarly, the second origin of the dorsal fin is posterior to the free rear tip of the pelvic fin.

The pectoral fins are usually much larger than the first dorsal fin. The caudal fin is large and triangular consisting of a deep subterminal notch.

Their background body color range from white to beige with a pattern of vertical stripes that range from dark brown to black in color. Most bullhead shark zebra species have 12 vertical stripes on their bodies which gives them their name.

How cute are they?

They are not voracious as other sharks of the world and hence can come under the category of being cute for fish lovers. Their slow wiggly movements whilst swimming is adorable to look at. Zebra bullhead shark images are quite stunning.
