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.

Comadreja Enana

The Common Fat-tailed Mouse Opossum (<em>Thylamys pusillus</em>) is a small marsupial belonging to the genus Thylamys within the family Didelphidae. Like other members of its genus, this species typically stores fat in its tail, which becomes swollen during periods of food abundance and is metabolised during leaner times, a physiological adaptation that provides energy reserves. <em>Thylamys pusillus</em> is generally found in diverse terrestrial and aquatic ecosystems, often in dry woodlands, scrublands, and grassland habitats of South America. The species is assessed as Least Concern on the IUCN Red List, indicating it is not currently considered at risk of extinction. Detailed geographic range data are not available in the current record, but members of this genus are typically distributed across parts of Argentina, Bolivia, Paraguay, and Uruguay. Biological traits including average lifespan, body dimensions, and specific dietary composition remain poorly documented in the scientific literature, though Thylamys species are generally considered omnivorous, often consuming insects, small vertebrates, and plant material.
