Goose barnacles
>>
>>4795789
they're a specialized type of barnacle that lives in the body cavity of starfish
you dont need many body parts when you spend your entire life inside an animal, so legs, eyes, armor, anything that makes them recognizable as a crustacean is gone.
the only thing that's left is the digestive surface and reproductive organs, they basically get tapeworm-ified
this is seen in a lot of other crustaceans, like sacculina or basically any parasitic copepod
some look like living banana peels, others are barely recognizable as anything other than a blob of flesh
they're only recognizable as crustaceans from their larval stages, the nauplius, which i'm pretty sure all crustaceans have in common

They probably cant be kept in tanks due to them being pelagic filter feeders, but what do i know, try it for yourself!

Well that kinda makes sense. They do look very similar. Horseshoe crabs, shrimps and ancient guys like the nautilus make it very obvious that crustaceans are ocean bugs, or the OG insects.
Makes me wonder, did the sea spider appear first or did it first appear on land? They're not related, but still.

i had a little aneurysm reading that comparison but let me teach you:
Horseshoe crabs arent related to isopods
Shrimps and isopods are from the subphylum crustacean and nautilus is the name for a genus of cephalopods! and the sea spider is more related to horseshoe crabs alongside spiders, since they all are chelicerata (a subphylum) and about who came first? the fossil record shows that the sea spiders are older than spiders

I fucking love vampire crabs bros I need these little guys in my life. Does anyone else own them? Is it worth it? It seems worth it. Is it smart to mix their different colour morphs?
>>
>>4797874
Ah yes, the famous peacock mantis shrimp. Also known as the flaming faggot of the seas. His rainbow colours and fancy eyes tell of a 'tism that cannot be defined in even the most elaborate of self-defined sexualities.

WOT incoming.

I had them, or still have them.
Bought two of the normal purple ones (Geosesarma dennerle) in 2007. Both died. Bought another pair in 2009. Both died. Bought another pair in 2010. Reproduced like rabbits and i had a large colony until 2018, when i made the mistake of redoing their tank- never change a running system. All males fought for terrirtoy and killed themselves, had only two female that werent pregnant and also died later in 2012 (old age, they die after two years). Bought other two from a store in 2021, one died, bougt another one, both lived for one year, then died. Bought a pair of red ones (Geosesarma hagen) 2022, both turned out to be male, exchanged them to a breeder for four captive bred ones (now Geosesarma tiomanicum)
Asshole breeder told me they were two males two females, i trusted him but i turned out three males one female. on male became violent and killed the two other males. Then i did redo the tank, found the alpha male and the female, which looked still brown (juvenile) but somehow pregnant. I did redesing their tank like this https://www.youtube.com/@IndoorEcosystem/videos guy here does his tanks (watch him, good videos) and now the female is gone, i cant find her, i see the male occasionally but not her. i hope shes still alive and carrying babies.
Important: The death toll as i have shown is catastrophic cause most of them are wild caught. its like russian roulette cause they are treated like shit during import and arrive weak or already dieing. get captive bred ones if possible. i dont get why more people bred them, you dont have to do anything, they are basically land CPO crayfish. And no, never, NEVER mix differend colours because those are not morphs but species. theyll fucking massacre each other.
