110 individuals removed as of 2 Nov 2025
[10/12/2025 4:52:34 PM]
After one week of removing this species, 47 individuals have been removed and still, more remain. Most of these where of sand grain size
[10/12/2025 4:51:14 PM]
This species is in the process of being removed. This is the only snail species that is successfully reproducing and it's offspring eat all the other snail species offspring.
Will burrow in and out of the sand in search of prey. Seems to hunt other snails and clams

Ecology Notes

Looks to be too disruptive as it eats young cerith snails and clams. May need removal for a balanced system if a natural predator cannot be found.

Reproduction Notes

Highly successful breeder.
