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 Extinguisher-moss

<em>Encalypta vulgaris</em>, the common extinguisher moss, is a acrocarpous moss in the family Encalyptaceae, classified as Vulnerable by the IUCN Red List, indicating a concerning decline in populations across parts of its European range. The species is documented in Belgium, Denmark, Luxembourg, Norway, and Portugal, where it is native to European calcareous habitats. <em>Encalypta vulgaris</em> typically grows on dry to moist calcareous rocks, soil banks, old walls, and disturbed ground with base-rich substrates, often in open or semi-shaded microhabitats. The common name refers to the distinctive elongated calyptra, a cap-like structure that covers the developing sporophyte and resembles an old-fashioned candle snuffer or extinguisher. The calyptra is persistent and fringed at its base, a diagnostic feature of the genus <em>Encalypta</em>. This moss is sensitive to nitrogen pollution and habitat disturbance, and its Vulnerable status reflects the loss and degradation of calcareous grasslands and rock habitats across Europe due to agricultural intensification, urban development, and changing land management. It plays a role in soil stabilization and moisture retention in the rocky and disturbed habitats it colonizes. Conservation of calcareous habitats is essential for maintaining populations of this and many other specialist plant and lichen species. Biological traits of this species remain poorly documented in the scientific literature.
