You've seen fireworks that look like jellyfish, but what about a jellyfish that looks like fireworks? The E/V Nautilus filmed this rare Halitrephes maasi jellyfish glowing like a firework at a depth of 4,019 feet (1,225 meters) off the coast of Baja California, Mexico. (📷: Ocean Exploration Trust)

For the #SciArtSeptember prompt: illuminated & a bonus mesopelagic #invertebrate for #InsertAnInvert2024 it’s my #linocut of the #bioluminescent firefly squid! The firefly squid (Watasenia scintillans), also called sparkling enope squid or hotaru-ika in Japan, live at depth (200 to 400 m) & 🧵
My linocut print shows the firefly squid against a white background on the left side of the square so you can see the whole animal and then its reflection is shown on the right against dark blue so you can see how its bioluminescence would appear underwater with fluorescent blue spots. On the left it’s a deep orange-pink squid with large gold and black eye. On the right you can see its body is covered with bright blue spots.  The print is 8" x 8" (20.3 cm x 20.3 cm) on white Japanese kozo (or mulberry) paper.

#SciArtSeptember 4: Azure. The coelacanth, a long-extinct creature that was accidentally discovered alive. Though it may look like just another type of fish, it is more closely related to us than other fishy inhabitants of the ocean. #SciArt

A little narwhal in the style of a medieval curio, mounted on a panel. Two ideas were overlapping in my mind: Narwhals’ tusks can distinguish changes in water temperature and chemistry; the horns of unicorns purify water and detect poison. 🦄 - #SciArtSeptember Day 9: Ivory
A photo of a small narwhal sculpture on a patterned board. The narwhal is made from white clay and coloured to resemble ivory. The piece rests on a wooden table next to a penny, for scale.

Fishy Friday: Bathypterois sp., a tripod fish. Solitary and stationary, these deep-sea denizens perch above the seafloor using specialized fin rays and face into the current. When an unsuspecting copepod or other tiny crustacean drifts by, this animal is set to snack. #Doldrums, 2,040 meters

Hands full of algae, she wades waist deep in a disgusting swamp, amazed by the heavenly microscopic life all around them.
