This was from my very first night dive. It was such an interesting experience seeing fish resting compared to their day time behaviour.
Bluespotted Ribbontail Ray (Taeniura lymma)
Klunzinger's Feather Star (Lamprometra klunzingeri)
One of the immediate differences I noticed diving at night as opposed to the day time was the amount of echinoderms that become active and visible.
The markings and movements of this klunzinger's feather star were mesmerizing. I will have to go back and take some video footage, the photograph doesn't do it justice!
A smaller fish that was sleeping amongst corals for safety.
This sea cucumber was massive. I wish I could have gotten a clearer image of it.
