Ecology

Found on reefs. The individual photographed was walking in a shallow tide pool.

Habitat

I photographed an individual in a tide pool in Arasaki. The waves were a little high, so I was hesitant to enter the deep rocks, so I was observing the tide pool. I found a Goniobranchus tinctorius on the rocks that I usually use as an entrance to the sea. It was walking in water 30cm deep.
