Both terrestrial and aquatic invertebrate and vertebrates enter into estivation.

The meres support abundant aquatic invertebrate species, especially beetles and bugs, with some rare species on record.

Silver perch appear primarily to be a low-order predator of small aquatic invertebrate prey, with occasional intakes of small fish and vegetative matter.

They have a complex life cycle which comprises vegetative forms in two hosts, an aquatic invertebrate (generally an annelid) and an ectothermic vertebrate, usually a fish.

Fenthion has been found toxic to fishes and other aquatic invertebrates.
