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.

Cliostomum corrugatum is a crustose lichen in the family Ramalinaceae, notable for producing characteristically wrinkled or corrugated apothecia that distinguish it from related taxa. The genus Cliostomum is a small group of saxicolous and corticolous crustose lichens with a disjunct distribution in temperate and boreal regions of the Northern Hemisphere, including Europe and North America. The thallus of Cliostomum corrugatum is thin and pale, often nearly immersed in the bark substrate on which it grows, while the pale tan to cream apothecia are flat to slightly convex with the distinctive corrugated or rugose surface. The species is found on the bark of deciduous trees in old, undisturbed woodland, including veteran oaks, beeches, and other broadleaved trees with stable, relatively unpolluted bark chemistry. Cliostomum species are considered indicators of ecological continuity in woodland habitats and are included in lists of ancient woodland indicator species in northwestern Europe. The species is sensitive to air pollution, particularly sulfur dioxide and nitrogen compounds from agricultural and industrial sources, and declined significantly across industrialized regions of Britain and Europe during the 20th century. Recovery has been noted in areas where air quality has improved. The species is of conservation concern in several European countries.
