Southern Biscuit Star (Tosia australis) endemic to the temperate waters of southern Australia.
“We look at mass strandings, the fact that they stand by each other. Everything about them is social. Everything.”
A South Korean designer named Jeabyun Yeon has created a conceptual scuba mask that will allow humans to breath underwater without the aid of an oxygen tank. It is called Triton, and mimics the gills found on fish to draw oxygen from the water to supply breathable air for humans. How exciting.
OH MY GOD THIS IS SO COOL.
the future is now
*not a mask but an awesome type reg
(plural salps, salpa, salpae or salpa) a barrel-shaped, planktonic tunicate. It moves by contracting, thus pumping water through its gelatinous body. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton.
Etymology: Neo-Latin, special use of Latin salpa < Greek sálpē - kind of fish.
Top Snail. (divindk)
So this is labeled a Jeweled Top Snail (Calliostoma annulatum, alt. common name Purple-Ringed Top Snail or Purple-Ring Top Snail) in tags, but the shell shape looks off to me? Too rounded, with distinct bends where the whorls meet. Then again who ever knows with marine snails- shell plasticity is very much a thing, as are more traditional forms of morphological variation. Which is part of why they’re great. Anyway the coloring is right and the shape isn’t THAT far off. It’s a Pacific species and I’m very much an Atlantic girl so I don’t know much about it.
Pretty though. <3
Here is a definite Calliostoma annulatum in case anyone cares. They’re a mostly subtidal species which lives on the stalks of seaweeds, esp. kelp, though they’re occasionally also found in the low rocky intertidal. They’re omnivorous, scavenge dead fish, and can hunt (known to eat sea anemones and attack nudibranchs), but mainly graze on various fouling organisms attached to the kelp such as diatoms, bryozoans, etc. as well as the kelp itself.
