tidepool gunnel
A small marine fish (Pholis nebulosa) found in tide pools and shallow coastal waters.
I found a tidepool gunnel on the rocky shore.

Kanji form is seldom used; the katakana spelling is standard.
The origin is uncertain; the kanji 銀宝 literally mean 'silver treasure', possibly referring to the fish's appearance.
