Water Bear (tardigrade)

These organisms are generally found in longer sludge ages and are very sensitive to ammonia, so their presence generally indicates that good nitrification or ammonia removal is occurring. Water bears have eight legs with four claws on each and short/ stout bodies in the shape of a cylinder. Water bears prey on algae, nematodes, and rotifers.
