Happy (belated) #AntarcticaDay! This continent and associated marine environment are critical for the entire planet. And human activities are already causing major shifts in this remote region of the world.

Factlets;

Thread: Today is #AntarcticaDay, a day to celebrate the treaty that recognizes Antarctica as a preserve for peace and scientific study.
It also feels like the perfect day to share this exciting news.

Happy #AntarcticaDay! Here I am almost 20 years ago, rising above the McMurdo Sound sea ice with Mount Erebus steaming in the distance. I still think about Antarctica all the time.

(working in Antarctica led, in a very roundabout way, to me studying Indo-Pacific reef fishes & biodiversity)

Happy Antarctica Day to those celebrating! Consider toasting the day with a warm and comforting Fry's Cocoa - it worked for "Scott at the South Pole," right?

Happy #AntarcticaDay, everyone! Today Dec 1st commemorates the anniversary of the signing of the Antarctic Treaty in 1959.

Remember: there's more than (truly amazing) whales 🐳, seals 🦭 and penguins🐧 in its icy waters, and they also deserve some (research) attention and resources 🪸🪼.

Since the last one went over so well...another amazing Antarctic punk-rock crustacean..I believe is the amphipod Epimeria sp. 🧪🦑🇦🇶🌍🪱

I’m am very very tired so an extra wild amphipod 🤘 #AugArthroAwe #SciArt 🦑

Happy Halloween! Today, I bring you one of the weirdest (and COOLEST!) creatures collected on our research trips ...a giant amphipod (Paraceradocus sp. I believe). They burrow in this slit-like holes in muddy sediments! Found on our research cruise to East Antarctica in 2023 (NBP23-03). 🦑🇦🇶🧪🦑🐧

#Antarctic #amphipods are wild!

Currently 564 amphipod species are known in the Antarctic and 417 species in the sub-Antarctic! Commonly known as sand hoppers, sand or sea fleas, scuds, or sideswimmers.

Now we're talkin' ! Pix of the Antarctic Labidiaster annulatus with arms extended into the water! These use fairly big trap-like structures called pedicellariae to capture krill! This image from www.oikonos.org which has sadly taken down their field guide to Antarctic species. #echinoday
