The invisible glory of Octopus cyanea (the Day Octopus)! Can you see it before it moves? #CephalopodWeek #cephalopod #octopus @TheOctoNation @scifri

@hinkonzundamon @postofficebaba あんまり理由になってないと思う。アイドル文化って気色悪いもんだな。大人の人間に彼氏彼女がいることで失望するファンとやらは惨めな人たちだな

@postofficebaba アイドルって言葉を検索して wikiで見てみてー なんで彼氏がいたらダメなのか分かるのだ これは女性アイドルに限らず 男性アイドルにも彼女がいたらダメ 定義的にも商業的にも意味がある

一読いただけますと幸いです。

@alexriesart @FengZhuDesign It really is good. I remember it being described as covered in spikes, but you manage to make that look sleek instead of messy and clunky

@FengZhuDesign Thanks Feng! Means a lot coming from you.

My Shrike appears...

@Superloris I'm not sure. I had to move on...

@CephWarden Did it manage to free itself?

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

Tentative

A lone squid passes under a surface sparkling with rain

@limaichay @TUExplorer1 You're right, the original source identifies it as a kitefin shark.

@CephWarden @TUExplorer1 I don't think so as cookie cutter have a more cylindrical body shape, a distinctive collar, a light brown profile, a dorsal fin that positioned way back at near the tail and finally a distinctive suction shaped jaw.

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

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

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

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

@ArneKuilman No, I didn't know that!

@CephWarden Did you know their multiple distinct species recognizable by different patterns on their pectoral fins? This the most common one.

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'.

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.

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.

An Abdopus, perfectly camouflaged in a tidepool.

A downed pteropod restarts its engine and takes off

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