Clawed enope squid

Chroococcus turgidus is a relatively large-celled species of cyanobacteria in the family Chroococcaceae, one of the more frequently cited and widely distributed members of the genus. Its specific epithet turgidus refers to the swollen or turgid appearance of its cells, which are notably rounded and plump. Chroococcus turgidus has been documented from freshwater habitats across a wide geographic range including Europe, North America, Asia, and other regions, reflecting its cosmopolitan distribution. The cells occur in pairs or groups of two to four within a stratified, often amber-brown gelatinous sheath. It is found in the plankton and periphyton of standing and slowly flowing freshwater bodies, on damp soils, and on submerged rocks and other surfaces. Chroococcus turgidus is one of the type or reference species frequently illustrated in classical treatises on freshwater algae and cyanobacteria. Its relatively large cell size compared to other Chroococcus species facilitates identification in microscopic preparations. The species contributes to primary production in freshwater ecosystems and is part of the diverse community of cyanobacteria that inhabit lentic and lotic freshwater environments. It has not been assessed by the IUCN.

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.
