Description:

Scarlet skunk cleaner shrimp Lysmata amboinensis アカシマシラヒゲエビ Reticulate hookjaw moray Enchelycore lichenosa コケウツボ Oshima, Tokyo 東京都大島町 Lysmata amboinensis is commonly only found in the summer here near Tokyo. I believe they are part of an abortive migration, riding the Kuroshi Warm Current from warmer southern seas up here, but perish in the fall or winter when the waters cool. I believe this moray receiving the shrimp's cleaning services is Enchelycore lichenosa, judging from the teeth and the curved jaw/mouth.
