First dive of the year! and in perfect season for Norway King crab. Was cold in the water though, a whopping 0 C in the first 5m 🤿 🦑 Taken 7/3/2026 Camera: Olympus TG5 #crustacean #nordicdiving #scuba #naturephotography #underwaterphotograpy #lithodesmaja

This year has been quite good for Surmullet (Mullus surmuletus) in Sweden, especially on night dives, saw several this past weekend. 🤿🐙🦑 Taken 9/11 2025 Camera Olympus TG-5 #aquaticlife #marinelifephotography #naturephotography #nordicdiving #scuba #underwaterphotography

#MolluscMonday with piping fresh mollusc photos from the weekend, this time we got the Velvet dorid (Jorunna tomentosa) as our featured species, this is one of the larger species found in Sweden, so often quite easy to spot. Taken 12/7 2025 at Fossens Camping, Gullmarsfjorden, Sweden Olympus TG-5

Once again it is #MolluscMonday with piping fresh mollusc photos from the weekend, this time a for me new species, the Crystal sea slug (Antiopella cristata), and i have to admit, it is one of the prettiest nudibranchs i've ever seen 🦑🤿 Taken 6/6 2025 Camera Olympus TG-5

#MolluscMonday is here again, and after a longer hiatus, i have been able to get into the water once more This time it was mainly Orange-brown aeolids (Aeolidiella glauca), a rather unassuming species of nudibranch Taken 3/5 2025 in Gullmarsfjorden 🦑🤿

Another week, another #MolluscMonday, and once again, there's piping hot fresh nudi photos from the weekend. 🦑🤿 This week we have the nudibranchs Acanthodoris pilosa and Dendronotus lacteus Taken 15/3 2025 Camera: Olympus TG-5

A rainy and cold #MolluscMonday it is, but this week, I once more got some piping hot nudibranchs fresh from the cold seas of Sweden. Taken: 23/2 2025 Camera: Olympus TG-5 🦑🤿

This #MolluscMonday we got some piping hot fresh nudibranch photos :) A Coryphella verrucosa and what i think is a Idaliadoris depressa(?) Both taken 9/2 2025 🤿🦑

What better way to start the week than with a cute little bobtail squid (unsure if Sepietta oweniana or Sepiola atlantica) for #MolluscMonday? These cuties are present all year round, but prefer to be out after dark, which is hard in summer here Taken 2023-11-04 on Divers Night in Lysekil 🤿🦑

Who is featured this #WormWednesday? Well that would be the King ragworm (Alitta virens), sometimes known as Sandworm. While it may not reach the sizes of its sci-fi counterpart of Arraksis, it is a species that can grow to quite the size (20-30 cm according to Artfakta.se) Taken 9/5 2021 🤿🦑

Oh Worm? Another week, another #WormWednesday, still no good worm photos this year, so I got a Sea mouse (Aphrodita aculeata) from last year instead for now. In my opinion, it is one of the prettier polychaetes we got in the Nordic seas :) 🦑🤿 Taken: 30/04/2023 Camera: Olympus TG-5

Well would you look at that, it is #WormWednesday, sadly i don't got any good worm photos this year, but here, have a Oxydromus flexuosus (unsure if it has a English common name, in Sweden we call it "Green-white flailing worm") that i took a few years ago Taken 13/11 2021, Camera: Olympus TG-5 🦑🤿

I was recently tipped off by another local marine biologist that "Mud diver shrimp" (Processa nouveli) is a thing, and well... they are quite common on night dives. So you learn something new every day, had completely overlooked these cuties while over the soft bottom looking for 🦑

A bit late for #WorldJellyfishDay because I totally did not forget the date or anything, Nuh uh ‹_‹. Aaaanyways, have a Crystal Jellyfish (Arquorea vitrina) taken on Divers night in Lysekil 2024 🤿🪼🦑

Well would you look at that, it is #SeaslugDay! time to post some nudibranch photos, this photo of a Facelina bostonensis, which we call Dragon nudibranch in Sweden, was taken in November last year, nudibranch season hasn't quite started up in my area just yet, but soon 🤿🦑

Haven't posted on my scuba blog in ages, but i guess here goes? The latest underwater adventures in the cold nordic waters :) 🤿🦑 swedishdiving.blogspot.com/2024/06/jord...

Scientists raise the alarm: Too many harbour porpoises dying in nets. In Danish coastal waters over 900 die each year vs a 24 death limit that would keep Belt Sea population stable. In 2012 & 2016, there were around 40.000 individuals, by 2022, only 14.000 left.  🧪🦑🌎 tech.au.dk/en/about-the...

Finally broke my long surface interval from diving this weekend, while waters were cold, it was so nice to be back in business! Got some photos too, but i forgot to turn off the camera between the dives, so it ran out of battery on the second dive, when all the nicer things showed up 🤪 🦑🤿

Another Wednesday, another reason to be pink. This is a Bryer's Nut crab (Ebalia tumefacta), a tiny species of crab that can be found on sandy, rocky and gravel seafloors. this particular individual was seen during Diversnight in Lysekil 2023 (no clue how i even spotted it) 🦑🤿📷🦀

On Wednesday we wear pink! Though the name of the nudibranch is Violet sea slug (Edmundsella pedata), i'd say this one from Väderöarna archipelago is of a sufficiently pinkish colouration, right? 🤿🦑 #Nudibranch Photo date: 2021 07 24 Camera: Olympus TG-5

Happy flatworm Friday everyone, here have some Candy-striped flatworm (Prostheceraeus vittatus) photos taken July and September last year 🦑 🐛

Hello there bluesky! I have come here to marine biologist and chew bubble-gum, and i am all out of bubble-gum #MarineLife 🦑
