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.

common intertidal amphipod

<em>Gammarus locusta</em>, commonly known as the common intertidal amphipod, is a crustacean in the family Gammaridae. Its conservation status has not been formally evaluated by the IUCN. The species is recorded from Denmark, Norway, Portugal, and Sweden, indicating a distribution along the northeastern Atlantic coast of Europe. It typically inhabits intertidal and shallow subtidal marine and estuarine environments, where it is found among algae, under rocks, and in sediments. Gammarus amphipods are ecologically important as detritivores and as prey for shorebirds, fish, and other invertebrates in coastal food webs. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
