満月の夜、カニの産卵

オカガニの産卵というか放幼を見て来ました。オカガニのほかにカクレイワガニ、ベンケイガニ、ヤドカリも産卵のため、波打ち際に集まっていました。

満月を眺めながらロマンチックな一夜でした。^^

A Land Crab heading toward the sea. It went in up to one or two metres offshore so I couldn't photograph it. Watching with a torch, a few seconds after entering the water it shook its body underwater and released its larvae. The water around the crab was blanketed in larvae, like a smokescreen.

Percnon guinotia.

Benkei crab.

Land hermit crabs were also heading to the sea to spawn.

A Sesarma also making its way back to its burrow.
