Dreissena is a genus of small freshwater mussels in the family Dreissenidae in the class Bivalvia. They are found attached to firm substrates by threads from underneath the shells and are the only freshwater bivalves to attach to hard substrates in high densities while having a planktonic larval stage. They are considered the most aggressive freshwater invader in the world because of their ability to invade environments in every one of their life cycle.
The royal spoonbill also known as the black-billed spoonbill, occurs in intertidal flats and shallows of fresh and saltwater wetlands in Australia, New Zealand, Indonesia, Papua New Guinea, and the Solomon Islands. It has also been recorded as a vagrant in New Caledonia. The royal spoonbill lives in wetlands and feeds on crustaceans, fish and small insects by sweeping its bill from side to side. It always flies with its head extended. Widespread throughout its large range, the royal spoonbill is evaluated as Least Concern on the IUCN Red List of Threatened Species.
Chilotilapia is a genus of freshwater fish in the cichlid family. It contains the sole species Chilotilapia rhoadesii, the Malawi bream, which is endemic to Lake Malawi in East Africa, where it prefers areas with muddy substrates from the shallows to quite deep waters. Its primary food consists of Melanoides and Lanistes snails. It can reach a length of 22.5 centimetres (8.9 in) TL. Though commonly called a "bream", this is due to its looks as it is quite unrelated to the breams proper, which are cypriniform fishes. This species is also found in the aquarium trade.
