amphipoda

Mature female. Note smaller horns. I'm noticing variation akin to isopoda. Might see some cool mutants as i progress.

Mature male with well-developed horns. These are essentially goats of the peracarideans, males use the thickened spiny bases of their antennae like antlers and headbutt other males.

Round two! I have several males and females and this time, and this time i'm educated better. You can tell theyre looking at you because they point with their antennae like crayfish. They also headbutt like rams haha it's adorable. Talitridae FTW! They ship well too ;)

Breeding experiment was successful, like isopoda, these hold young in their marsupium, these young are called 'mancae' (singular- manca) and remain close to the mother, of whom cares for them until their next molt.

'big-eyed sand flea' Large terrestrial amphipoda that emerge during low tide to feed on detritus and algae in the wrack along the median high tide mark.
