كلب البحر أسنان مشطِية

<em>Centroscyllium nigrum</em>, the combtooth dogfish, is a deep-sea shark in the family Etmopteridae, assessed as Least Concern on the IUCN Red List. The species has been recorded from Chilean waters in the southeastern Pacific Ocean, where it inhabits deep oceanic environments on continental slopes. Like other members of the genus <em>Centroscyllium</em>, it possesses a series of small, comb-like teeth suited for grasping slippery prey. The combtooth dogfish is a small shark, characteristic of the lanternshark family in its modest body size and deep-water lifestyle. It is presumed to feed on fish, cephalopods, and crustaceans encountered in the midwater and benthic zones of its deep-sea habitat. As with many deep-sea elasmobranchs, detailed information on its population size, reproductive biology, and ecological role is limited. The species is currently not considered at significant conservation risk. Specific body length and weight data are not available in the current record.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
