ninja lanternshark
A species of deep-sea shark (Etmopterus benchleyi) named for its dark coloration and stealthy appearance. The name is a direct loan translation of the English common name.
The ninja lanternshark is a small shark that lives in the deep sea.
Katakana spelling is standard for this species name; usually written in kana.
Kanji spelling is rare and may be encountered in some contexts, but the katakana form is strongly preferred.
The Japanese name is a calque of the English 'ninja lanternshark', combining 忍者 (ninja) and カラスザメ (lanternshark, lit. 'crow shark'). The species was described in 2015 and named after Peter Benchley, author of 'Jaws'.
