Well we only got in one more dive due to windy weather. These are from a night shore dive off Turtle Point. It’s cool cause you can see what some of the corals look like when their polyps are open and feeding nocturnally.
This is a Basket Star, a large brittle starfish:
Below’s a Lobophylia (I think), and classifies as an LPS (Large Polyped Stony) coral. At night the big round polyps are somewhat deflated/shruken, and the rows of short tentacles are filter feeding for tiny plankton.
Below a Gorgonian that feeds almost exclusively on plankton, as opposed the more common hermatypic corals than live mostly on energy from their symbiotic photosynthetic zooxanthellae algae.
Here’s what the little knobby stony corals look like at night with the polyps open for feeding. During the day their zooxanthelae feed them.
