Acute Bladder Snail (Physella acuta)

Family: Bladder Snail Family (Physidae)

IUCN Conservation Status: Least Concern

A common resident of ponds, lakes and streams across much of Europe and North America, the Acute Bladder Snail spends the vast majority of its life underwater but can only extract oxygen from air, so must regularly climb to the surface to re-fill an air-filled bladder within its shell (earning it its name.) Hardy and fecund, members of this species feed on aquatic plants, algae and detritus and rely on their curled shells for protection against their many predators, which include numerous small fish, freshwater turtles, non-parasitic leeches and larger carnivorous snails - should a predator grasp or bite them, Acute Bladder Snails are capable of using a unique muscle to furiously waggle their shell in an attempt to shake them off before detaching from the surface they are attached to and attempting to sink to safety. Like most gastropods Acute Bladder Snails are hermaphrodites (with every individual producing both sperm and eggs) and are capable of fertilizing their own eggs, although where possible they show a preference for mating with other members of their species instead (likely because self-fertilization reduces the health and fitness of offspring due to a lack of genetic diversity.) Following mating, members of this species lay dense clusters of tiny eggs covered by protective gelatinous sacs, which they typically attach to the stems or leaves of aquatic vegetation.

bouncing off that last ask, any thoughts on rose's aliens? squiddles or otherwise

all the secrecy and ambiguity is working on me bc the only thing i'm confident about wrt rose's aliens is that i have no idea that they're going to be. i can't fall in with the "she's gunna make the squiddles/horrorterrors, it's all gunna be one big time loop!" crowd bc that's very clearly what they WANT us to think.

one the one hand, using hs2 to tie back into a mysterious and deliberately-unexplored element of the original homestuck would be totally contrary to the theme of breaking cycles which was central to homestuck's ending, not to mention just totally uninspired... on the other hand, using an uninspired twist to make hs2 essential to hs1 is exactly the kind of thing dirk would plan for in his obsession with the good old days, and it would be really interesting to see him try and fail to do that in a kind of subversion of the 'trying to go back and change time but simply causing the original events to happen anyway' cliche. it largely depends on what rose's intentions are - since we know very little of what her end goal here is, beyond simply bonding with her absent father - and how willing she actually is to go along with dirk's reactionary masturbations. (part of me is entertaining the idea that the squiddle red herring is distracting us from the fact that it's dirk's horsepeople who will go on to become the horrorterrors, since there's a kind of unspoken relationship between musclebeasts and horrorterrors in hs.)

even if rose's aliens do go down the expected cephalopod route, i'm not sure if i should expect them to match dirk's aliens and just be people with squid biology, or if i should expect them to contrast the satyrs and be more monstrous Old One-type creatures. again, depends on if rose is following dirk's "let's do homestuck again" philosophy or if we should expect her species to align more with her own storytelling interests; in which case, something complacency of the learned-inspired, i guess?

disra senkovi really laid he foundation for the most technologically advanced society in the setting just by being autistic about cephalopods hard enough

incredible

I think it would be incredibly cool to have an aquarium of nudibranchs as lil pets..

[seacreatures-daily]

Can you do a sea slug?

Costasiella kuroshimae (leaf sheep)

thanks for your request, it was really fun to draw! i want to draw more sea slugs in the future XD

I helped with a study of local freshwater mussels today. They're doing transect studies of the river and tagging and releasing the mussels they find. Later they come back and do it again to see where the mussels are moving to over the course of 10 years.

They glued stickers to a mussel and called it science

These are called heel splitters. That's not even the biggest one we found

I know the big oblong one in the middle is called a pistol grip and the green warty ones are pimplebacks, but I don't know how to ID the rest

They can live for decades and are parasites as juveniles. I should do a Wet Beast Wednesday post on mussels because there's some interesting stuff about them

Phyllodesmium is a species of aeolid nudibranchs; of which tend to be and this species IS --- marine gastropod molluscs. These are in the family Facelinidae. These beautiful nudibranchs have tendril-like appendages on their thin body and as you can see are soft-bodied nudibranchs similar to most other species. They come in different variations; from non-transparent to transparent, with transparent offspring being called Phyllodesmium opalescens, Phyllodesmium iriomotense, Phyllodesmium poindimiei and other terms. Non-transparent versions of this genus are called Phyllodesmium briareum, Yellow-tipped phyllodesmium, Phyllodesmium serratum and other terms likewise. These are one of the more uncommon species, as these tendrils encompass their entire body. Its prey are  octocorals; a kind of soft coral, and Some of the species are also unusual in that they are able to utilize zooxanthellae from their prey, in a symbiotic relationship that provides them with extra nutrition from photosynthesis, hence they are commonly called "solar-powered" sea slugs.
