For the first time ever, stygiomedusa gigantea, a gigantic jellyfish was caught on video by scientists in the Gulf of Mexico. There have only been 115 sightings of this deep sea jellyfish in the past 110 years.
Eulagisca gigantea, the giant polynoid worm, is a species of marine Polychaete worm belonging to the family Polynoidae, the scale worms. This species is found on the seabed in the Antarctic Ocean. It grows to around eight inches long, and judging by the jaws, it is a predator, but little is known about its diet or behavior.
The area that appears to be the head is actually a retractable pharynx; the last photo shows what it looks like when the pharynx is retracted. (xx)
The pink skunk clownfish is a species of anemonefish from the skunk complex that is widespread from northern Australia through the Malay Archipelago and Melanesia. Like all anemonefishes, it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host. It is a sequential hermaphrodite with a strict size-based dominance hierarchy;
the female is largest, the breeding male is second largest, and the
male nonbreeders get progressively smaller as the hierarchy descends. They exhibit protandry,
meaning the breeding male changes to female if the sole breeding female
dies, with the largest nonbreeder becoming the breeding male.
A lot of other clownfish do the same thing as far as sexes. If you want to breed clownfish, you just get two juveniles and let them sort themselves out, one will become female. If the only ones available are adults, you get a big one and a much smaller one, and the big one is either female or will become female.
Because every color is a different wavelength, it’s possible to have a lens focused in such a way that only one color at a time is clear and others are blurry.
So it seems that the eyes of cephalopods rapidly “sweep” across every possible level of focus. It might all look like different shades of grey to them, but in just an instant, their powerful brain registers exactly which shades of grey come clear at exactly which levels of focus and tells the skin which chromatophores to switch on and off to match that shade as close as possible. *focusfocusfocusfocusblurblurblurblurblurblur* I don’t know what these other assholes are seeing but THESE greys in THIS situation sure seem to confuse them”
