dorsal fin is moderately high. The color of the dorsal surface is a range between white and cream depending on the shark. There are five large gill openings slightly in front of pectoral-fin mid-bases on the side of these sharks heads. Out of the five gill slits, the first gill slit is the largest and is closest to the front of the body. The smallest gill slit is the most posterior out of the five gill slits. Along with this, these organisms have a range of large to small vertical markings from the snout to the caudal fin of brown and black color. Depending on size,

aquarium trade, the study of marine ecology, and the impact these organisms have on other species. Conservation efforts have been put in place to limit the impact of humans on the zebra bullhead sharks. Laws have been put in place on the coasts of Asia in order to protect this species and its closest relatives. Although the zebra bullhead shark is classified as Least
Concern on the IUCN's Red list there is little information provided to fully understand the impact humans are having on these organisms.

pattern of the female shark is six to twelve times during a single mating season. The eggs are normally laid in rocks or fields of kelp. When eggs are hatched, the embryos feed on the yolk and hatch a year after they have been produced. The typical size of these hatchlings is 18 cm. The process of reproduction begins with a male grasping the pectoral fin of a female. The male inserts a single clasper into a female's cloaca.

including sea urchins and crustaceans. The prey they feed on can be found in rocky reefs and kelp forests where zebra bullhead sharks live. The range of these organisms within the marine habitat is from 50 meters to 200 meters. Zebra bullhead sharks are known to not have many natural predators where they live. However, in rare cases, larger sharks and human can be a threat to these organisms.

The zebra bullhead shark is a member of the bullhead and horn shark family, the
Heterodontidae. This organism is occasionally been referred to as the zebra horn shark, striped bullhead shark, and the zebra Port Jackson shark. These sharks receive their name due to their bull-like appearance because

The zebra bullhead shark's reproduction system is oviparous. Oviparous reproduction is the process of producing organisms by the hatching or laying eggs by a parent. A female shark lays two eggs at a time during the spring to the later summer near the coast of Japan. The typical seasonal spawning

from an external view involves the presence of a dorsal fin and anal fin. The dorsal fin on these sharks has a spine within it. The length of the dorsal fin is about 21 to 27% of the total organisms length. The first dorsal fin is high in the juvenile sharks, while in the adult sharks the first

The zebra bullhead sharks are characterized by slow growth which makes it difficult to cultivate them in the laboratory. Due to the slow growth and reproductivity that characterize these organisms human can have an impact. These organisms are important to humans in various ways including the

The zebra bullhead shark is of minimal interest to commercial fisheries and game fishing. However, due to the unique and attractive color pattern of these sharks they are a part of the aquarium trade around the world. These organisms are known to be carnivores and feed on a range of organisms
