I had just jumped into the water and had swam over to my favorite crevice where two lionfish live and saw this! I couldnt get a body photo as the tendril is extending from down an underlying crevice/cave where I know Scorpionfish/Rockfish live aplenty and didnt want to feel around. The tendril extended easily 16 to 20 inches down to the seafloor and two long prehensile "tongues" were feeling around through the detritus. The "tongues" almost appear to have suckers or something else on their bottom. I was on my way out to some clownfish colonies so I didnt stay around to take any more photos. Anyway, does anyone know what this is?
These soft bodied animals lives in crevices or burrows and extend the proboscis out to gather detritus & organic bits off the body. Rows of fine hairs called cilia on the surface of the proboscic function as a conveyor belt to bring the food back to the mouth which is safely hidden away. The interesting bit to me is that I've never seen a picture of one that wasn't green.
