Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 6 distinct biome types spanning the Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Tanzania), Asia (Taiwan, Thailand, Vietnam), Europe (5 countries), North America (United States), Oceania and the Pacific (Australia), and South America (Colombia, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

カリフォルニアホタルイカ

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.

東アジアで最も人気のある飼い鳥の一つであるジャワスズメは、灰色の羽毛、鮮やかな黒い頭部、特徴的な白い頬斑、明るい赤いくちばしを持つ印象的なフィンチである。インドネシアのジャワ島とバリ島が原産地で、アジア・アフリカ・アメリカの多くの地域に導入されている。開けた草地、水田、農地に生息し、稲作に被害を与えることがある。籠鳥取引のための深刻な捕獲圧力により、原産地では絶滅危惧種に指定されている。
