Nudibranch Snacks On The Ground

Occurred on May 23, 2023 / Lembeh, Sulawesi, Indonesia

Info from Licensor: "As we proceeded with the dive, we found a nudibranch about 5 cm long. It was neither particularly cute nor beautiful. Normally, I would have passed it by. However, something caught my attention, and as I observed it, I became fascinated. It opened its large mouth and covered the ground with its mouth. Then it opened its mouth wide again and covered its mouth over the ground. And then it would repeat the process slowly. I couldn't take my eyes off it. Apparently, it is the Family Tethydidae. This simple creature kept repeating its predation forever."
