Reproduction is aplacental viviparous, with females gestating two or three young at a time. Like other members of its genus, it is capable of producing light from a distinctive array of photophores. This species can be identified by its small size at maturity, long flattened head, and pattern of black ventral markings and a mid-dorsal line. It is known to be present only on the upper continental slopes off Colombia and Venezuela, at a depth of 283–439 m (928–1,440 ft). The dwarf lanternshark ( Etmopterus perryi) is a little-known species of dogfish shark in the family Etmopteridae and possibly the smallest shark in the world, reaching a maximum known length of 21.2 cm (8.3 in). #Octonauts #LearnAboutFish #SeaEducationforKids #DwarfLanternShark

These help the sharks camouflage themselves against predators and attract prey towards themselves. Several black ventral markings are light-producing photophores, and others are pigment-containing chromatophores. Juvenile males mature at 6.3–6.9 inches and females around 6.1 inches. A litter has 2-3 pups around 2.2–2.4 inches long each. They show aplacental viviparity, where a yolk sac sustains the undeveloped young until they are born. They most likely use their bioluminescence to draw prey towards them. BehaviorĪs a deep sea species, their diet primarily consists of krill, shrimp, and small fish.
They have been spotted at 928–1,440 ft depths on the upper continental shelf. Where do they liveĭwarf lanternsharks live in the Caribbean Sea, off the coasts of Colombia, including Barranquilla, Guajira Peninsula, and Santa Marta, Grenada, and the Los Testigos Islands in Venezuela.

The skin is covered with dermal denticles. On the short trunk, there are several fins, with the second dorsal fin being the largest. There are also small papillae and five gill slits. In contrast, females have only one lateral cusplet pair surrounding each main cusp. Sexual dimorphism exists in the teeth in the upper row, with a single cusp flanked by two pairs of smaller cusplets. Inside the mouth are 25–32 tooth rows in the upper jaw and 30–34 in the lower one. Its head consists of a fourth or fifth of the whole body of the shark. The largest specimen recorded was about 8.3 inches.
These sharks only reach lengths of 6-8 inches, making them the smallest sharks in the entire world. Interactions with humans Dwarf Lanternshark Scientific Classification
