Giant Basket Sea Star (night)

Astrophyton muricatum


During the day, it curls up into a tight ball shape to protect itself from predators. At night, it climbs to an elevated point to feed by extending its intricately branched feeding arms in a bowl-like shape in order to snare passing plankton and other organisms from the current.


Night dive in Bari Reef, Bonaire.

It's perfect that you got both shots and interesting to see the night and daytime behaviors! Great spottings :)

Hi Christine, I thought it was quite interesting because at first during the day we were wondering what these fuzzy balls in the corals were and then at night the mistery was solved :-)
