カリフォルニアホタルイカ

ボルチモアムクドリモドキ

ボルティモアムクドリモドキ（Icterus galbula）は北米東部〜中米で繁殖し、冬季は中南米へ渡る渡り鳥で、雄の鮮やかな橙と黒の体色が美しい。IUCNレッドリストでは軽度懸念（LC）に分類されており、メリーランド州の州鳥・ボルティモア・オリオールズのチーム名の由来でもある。メキシコ湾を一気に渡る長距離渡りを行い、針状の先が精巧に編み込まれた深い袋状の巣を木の枝先に吊り下げて営巣する。

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.
