Figure 3. True, False, Not given questions. The newly discovered shark species is called the painted hornshark. Heterodontiformes is an order with multiple genera and species. Genetic analysis confirmed that the newly discovered species is the same as Heterodontus zebra. The similarity in patterns and markings on the shark's skin is the main reason why the new species went unnoticed. Dr. Will White is a biologist who works at the Australian National Fish Collection (ANFC). The new species was initially identified through genetic analysis. The research vessel that found a living specimen of the new species was surveying seabed habitats near the eastern coast of Australia. The male specimen collected during the voyage was used as the reference for the species' scientific name. The painted horn sharks live at a depth range of 410 to 751 meters. The adaptation of human-like molars behind the rows of teeth in these sharks helps them crush prey like cowrie shells.

Shark the paired respiratory organ of fish and some amphibians, by which oxygen is extracted from water flowing over surfaces within or attached to the walls of the pharynx. Similarity the projecting nose and mouth of an animal, especially a mammal. Skin an individual animal, plant, piece of a mineral, etc. used as an example of its species or type for scientific study or display. Characterize a pair of appendages under the abdomen of a male shark or ray, or at the end of the abdomen of a male insect, used to hold the female during copulation. Genus an animal such as a snail, clam, or octopus which has a soft body. Many types of mollusc have hard shells to protect them. Gills the thin layer of tissue forming the natural outer covering of the body of a person or anima Snout describe the distinctive nature or features of. Specimen a long-bodied chiefly marine fish with a cartilaginous skeleton, a prominent dorsal fin, and toothlike scales. Claspers the state or fact of being similar. Mollusc a class of things that have common characteristics and that can be divided into subordinate kinds.
