Bogue are host to a wide variety of parasites, ranging from metazoans such as Digenean flatworms, Acanthocephalan spiny-headed worms, nematode roundworms, isopod and copepod crustaceans and Myxozoan cnidarians to the unicellular dinoflagellate Ichthyodinium chabelardi, a parasite that is lethal to eggs developing in ovaries.
The New Zealand flatworm Arthurdendyus triangulatus and the Australian flatworm Caenoplana alba have been introduced in the British Isles and are considered to be pest species because they prey upon earthworms and thus may negatively affect soil structure and fertility.
Three species of tunicate, one mollusk, one flatworm, and one sponge have been discovered in places ranging from Micronesia to New Zealand.
An extinction claimed to have occurred after the flooding is that of the Lake Pedder planarian (Romankenkius pedderensis), an endemic flatworm.
