Leaf scorpionfish ~Taenianotus triacanthus~ on marine macroalgae known as sea grapes. Bunaken, 🇮🇩 Leaf scorpionfish are camouflaged ambush predators which resemble a leaf. To be more convincing, they gently move their pelvic area to look like a drifting inert object. #marinelife #uwphoto
Yellow edged moray eel (Gymnothorax flavimarginatus) in Bunaken, 🇮🇩. Moray eels, one of the few predators of the venomous lionfish. A fascinating video of this can be seen at link.springer.com/article/10.1... #marinelife #uwphoto

Maroon clownfish ~Amphiprion biaculeatus~ with its symbiotic sea anemone the bubble tip anemone ~Entacmaea quadricolor~. Maroon clownfish are the most host specialised of the anemone fish and will associate almost exclusively with this anemone. Taken on the island of Bunaken, Indonesia.

A nice whiting ()Merlangius merlangus) caught during the Icelandic groundfish survey @mfri.bsky.social . While the range of this species reaches northern Iceland, it is not as common than other areas of Europe, and there is no targeted fishery.
Out on the Icelandic groundfish survey and here just a few of the fishes we get at the deeper stations ~400 m. (1/n) Sea tadpole - Careproctus reinhardti Greater eelpout - Lycodes esmarkii Doubleline eelpout - L. eudipleurostictus Arctic eelpout - L. reticulatus Vahl´s eelpout - L. gracilis

My poster is currently being printed, this is the joy I will endure in the coming days.
Kathleen@kathleencarson.bsky.social · 10mo agoUgh, and the do I/don't I talk to the person looking at my poster? Are they genuinely interested to just being polite? Do they want a minute to read it over? Or should I jump in and give them a pitch?
