Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Chile, Norway, Portugal, and Taiwan. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Clawed enope squid

Alequim

O tubarão-branco é o maior peixe predador da Terra, podendo atingir 6 metros de comprimento e 2.000 kg, habitando águas costeiras e oceânicas frias em todos os principais oceanos. São predadores de topo que empregam ataques de emboscada por baixo, direcionados principalmente a mamíferos marinhos, peixes de grande porte e aves marinhas. Apesar de sua terrível reputação, ataques não provocados a humanos são extremamente raros. Classificado como Vulnerável (VU), com populações em declínio devido ao corte de barbatanas, captura acidental e pesca direcionada, apesar das proteções legais vigentes em muitas jurisdições.

Clawed enope squid

The Clawed Enope Squid, Ancistrocheirus lesueurii, is a medium-sized oceanic squid in the family Ancistrocheiridae found in mesopelagic and bathypelagic zones of the Atlantic, Pacific, and Indian Oceans. It is the sole species in its family, representing a phylogenetically isolated lineage of deep-sea squids. The species is characterized by powerful, hook-bearing tentacles used to capture prey, an adaptation reflected in its common name. The mantle is muscular and elongated, bearing lateral fins, and the arms bear suckers modified into sharp hooks in adults. Ancistrocheirus lesueurii performs diel vertical migrations, ascending toward the surface at night and retreating to deeper waters during daylight hours. It is a voracious predator of fish and other squids, and is in turn preyed upon by sperm whales, large pelagic fishes, and sharks. Bioluminescent photophores are present on the body and arms, likely functioning in counterillumination or signaling. As a mesopelagic species distributed throughout major ocean basins, the Clawed Enope Squid contributes significantly to vertical carbon transport in marine ecosystems, processing organic material from surface waters and redistributing it at depth. Population status is unknown; the species has not been assessed by IUCN. It is occasionally recovered in the stomach contents of top predators and from deep-sea trawl surveys.
