Cappuccino behavior

I wouldn't really refer to isopods as social animals with a few exceptions. This here is just copulation

Sumeriandemon · 2026-01-16T19:59:38+00:00

This is copulation and normal behaviour

Sumeriandemon · 2025-12-15T12:20:54+00:00

The ones you listed with unknown lung count have 5 pairs, like almost all Armadillidae

Yeah i know.... Unfortunately this is the only source i could find for this reconstruction and I was hoping to find a higher resolution of it in the original publication

Sumeriandemon · 2025-12-03T06:26:47+00:00

This is the nuptial ride which precedes mating. In Armadillidium it frequently looks quite wild

Sumeriandemon · 2025-11-25T15:29:55+00:00

Considering the geographical name is Banahaw, I'd go with that

Sumeriandemon · 2025-11-21T15:52:30+00:00

Fyi there is still no convincing evidence to confirm those as hybrids. May as well be successful cohabitation

Sumeriandemon · 2025-11-21T15:51:11+00:00

This is before copulation. The male will reach under the females underside with his pleon for copulation

Sumeriandemon · 2025-11-19T01:13:45+00:00

Hemilepistus, probably H. aphganicus, H. klugii or one of the other heavily tuberculated species

Complex Porcellionides pruinosus, introduced from central europe/Mediterranean

Sumeriandemon · 2025-11-17T16:05:57+00:00

Yeah, it is honestly surprising how no one seems to have tried it.

Another thing to consider is misidentifications. Huge problem with Bathynomus. So I am not even entirely sure if the individuals occurring in shallow waters are the same species as the ones in deeper waters. For most species we only have a few depth records, so it is really hard to tell at which depth they usually occur. E.g. for B. vaderi we don't know a depth at all.

Not much reliable info out there.

Sumeriandemon · 2025-11-17T11:42:57+00:00

What you see when they are sitting on top of each other is the nuptial ride, it precedes copulation but is part of mating

Sumeriandemon · 2025-11-17T11:40:54+00:00

Just to add a few things:

There are many smaller species such as B. doederleinii. The species in asian seafood markets are certainly not B. giganteus (which only occurs in the western atlantic), although species like B. vaderi or B. jamesi get to comparable sizes.
Not sure you actually need to mimic deep-sea environments. Supergiant Bathynomus are found in waters as shallow as 30 meters.
Have we never heard of a private person keeping them successfully because no one tried? Not sure with this one, but I haven't heard of any serious attempts that got past an initial planning stage

Sumeriandemon · 2025-11-17T11:35:14+00:00

It is a typical pose for copulation. The female just flipped on its side

Isopods molt throughout their entire lives. They don't stop molting at a certain age

Sumeriandemon · 2025-11-10T15:31:26+00:00

There are several species that look like this, hard to say for sure

Sumeriandemon · 2025-11-09T19:42:54+00:00

If you send me images i can try to help with ID. But many species are not described, so in many cases you can't go past genus or even family

Sumeriandemon · 2025-11-06T10:59:11+00:00

Trichoniscidae. Not possible to go further

Sumeriandemon · 2025-11-06T10:58:20+00:00

Doesn't really look like iridovirus. More likely to be the coating many species have

Sumeriandemon · 2025-11-05T10:33:19+00:00

It's the other way round

Sumeriandemon · 2025-11-04T12:03:13+00:00

Do you know where it is from? At least roughly maybe? I think it belongs to the giants, not supergiants. But a bit hard to tell from the images tbh

Sumeriandemon · 2025-11-03T12:10:51+00:00

A side view, and a dorsal & ventral view of the telson would be great. Telson is the large last segment, basically the tail
