The Horned Shark is usually very lazy and spends most of it's time laying around on the bottom of the aquarium. This shark was so docile you could feed it by hand, though keep in mind that they do have sharp teeth and may bite if they feel provoked!
The Horned Shark (Bullhead Shark, Pig Shark, or Port Jacksons) gets it's name from the two horns you see sticking up just in front of the dorsal fins.
These are a small sharks reaching 38 inches (96 cm), and fairly easy to maintain. in a large aquarium. One challenge to keep in mind, however, with keeping the Horned Shark (Bullhead Shark, Pig Shark, or Port Jacksons) is that they are actually a "cool-water" shark and some may do poorly in a "tropical" aquarium.

Habitat: Natural geographic location: Eastern Pacific: central California, USA to the Gulf of California, and probably Ecuador and Peru. Sluggish, nocturnal, and mostly solitary species. Inhabits rocky bottoms, kelp beds, sandy draws between rocks, on sand flats, deep crevices and small caves and also large underwater caverns. Adults tend to return to the same resting place every day. They have broad muscular paired fins used as limbs for clambering on the bottom
Sex: Sexual differences: The medial edges of the male's pelvic fins are modified to form claspers. The claspers are tubelike organs designed to deliver sperm into the female's reproductive tract. As the males grow older the claspers become more pronounced. The females do not have these.
