snare

深海の生物は、本当に気味の悪い外見をしています(リンク先)。正式名称はChondrocladia lyraで、別名the harp spongeというようです。それは、vaneと呼ばれるこの種の生物の基本構造が、ハープの形のようだからです。

赤字のsnareは、名詞でドラムの「スネア」「(動物などを捕えるための)わな」という意味がありますが、他動詞でも「･･･を罠で捕まえる」という意味があります。英検2級くらいの知識ですね。ちなみに「誘惑する」「陥れる」などの意味もあります。さらに研究社『英和中事典』によればアメリカ英語の用法で「《主に米国で用いられる》 巧妙に〈…を〉手に入れる.」という意味もあるようです(Othello)。

You may remember the Monterey Bay Aquarium Research Institute (MBARI) from such discoveries as the Yeti crab, the squid with elbows and my personal favourite, the pigbutt worm, and now they’re back with footage of a new species of carnivorous sponge.

Seventeen years ago, Jean Vacelet and Nicole Boury-Esnault from the Centre of Oceanology at France’s Aix-Marseille University provided the first real evidence that a sponge could be more than, well, a sponge. They had discovered a new species of deep-sea sponge living in the unusual setting of a shallow Mediterranean sea cave, the inside of which mimicked the conditions of its usual habitat more than a kilometre below the surface. This allowed the researchers an unprecedented view of the sponge’s eating habits, and they watched as it snared its prey of small fish and crustaceans instead of absorbing bacteria and organic particles through their bodies, like most other sponge species do – including ones living in the very same cave.
