タガヤサンミナシ

The cloth of gold cone (Conus textile) is a large, highly venomous marine gastropod in the family Conidae found throughout the Indo-Pacific region, from the Red Sea and East Africa to Polynesia and northern Australia, in shallow coral reef environments, sandy flats, and rocky intertidal zones. The shell features a distinctive pattern of tent-like or overlapping golden and white markings on a pale background, resembling woven cloth — the source of its common name. Conus textile is among the most dangerous cone snails to humans, delivering a complex cocktail of conotoxin peptides via an extensible proboscis and harpoon-like radular tooth that can penetrate skin even through thick gloves. The venom paralyzes fish and mollusks, its primary prey. Human fatalities have been recorded from careless handling, earning this species a reputation as one of the most dangerous shells in the world. Conotoxins from C. textile and related species are of intense pharmaceutical research interest as highly specific ion channel blockers with potential applications in pain management and neurological drug development.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
