Cuttlefish silhouette

A tube worm hauling its tube across the sand

A squid in slow motion, under dappled sunlight

Tree lizards of the Yanbaru. I think we counted 17 on this one trail.

A ghost pipefish, looking exactly like a broken blade of dead seagrass, complete with crustose overgrowth

The subtle textures of a seahorse

This anemone planted perfectly on the front of this sea cucumber as if it's part of the animal

A downed pteropod restarts its engine and takes off

An Abdopus, perfectly camouflaged in a tidepool.

This reddish furtive octopus has been a common sight in the reefs at night lately. But I have no idea what species it is. I've seen it put on a white spot in the middle of its face sometimes but otherwise shows no particular body patterns that I've seen.

This thing looks like the body broke off of a toy bug, leaving only the legs. Yet it is as complete as you or me. A sea spider.

The remarkable demon stinger. So hard to see at first but it knows how to make itself be seen when it wants to. I don't get tired of watching it walk with its odd 'fingers'.

Hiding at the water's edge. Sorry buddy, but you were blocking my exit!

An odd looking siphonophore, probably Abylopsis tetragona. I've seen a few types of these siphonophores that come in this sort of transparent 'box' but this was by far the largest at about 5cm

A ghost pipefish. When something so beautiful tries so hard not to be seen

After over 20 years and 1000 dives, I finally went diving in my native Hokkaido. Under the ice in Shiretoko, water temperature -2C. Music: Ice Age (deadmau5 remix) by How to Destroy Angels

A little purple fairy fluttering through the reef, the batwing sea slug Sagaminopteron ornatum. Perhaps my favorite sea slug. Filmed in slow motion.

A lone squid passes under a surface sparkling with rain

Tentative

This jellyfish got a tentacle snagged on a coral, now looks like a strange balloon dancing in the sunshine
