some more isopods! these are Porcellio laevis “Dairy Cow” with an additional mutation that removes pigment from almost all of the body (compare a normal cow pattern baby… calf? in the backround).
the morph has been isolated to form Porcellio laevis “White” by multiple keepers. I have a fairly low incidence of solid white ones, so I haven’t bothered to breed for these, but I’ve isolated the handful I have to see if it’s possible.
these few are probably the most massive isopods I’ve kept. laevis can get huge in old age on a good diet, and holding these you can really feel their weight!
oh, cool anatomy moment! terrestrial isopods actually have 4 antennae like most crustaceans (think shrimp) and their big ones are actually the second pair of antennae!
antenna 1 has been reduced to tiny nubbins that are easily overlooked with the naked eye. however, this old laevis is so large that my camera pictures are high enough resolution to see his first antennae (I think)
they’re the pair of little white spikes on the inside of his second antennae pair
