Japanese spear lobster
A species of lobster (Linuparus trigonus) found in Japanese waters. The name is usually written in katakana as ハコエビ.
The Japanese spear lobster is caught in the seas around Japan.
Hiragana spelling is also used, though katakana is more typical for animal names.
Kanji spelling exists but is uncommon; the word is usually written in kana.
From 箱 (hako, 'box') + 海老 (ebi, 'shrimp/lobster'), likely referring to the boxy shape of its carapace.
