Abstract

The aim of this study was to identify and describe the ecological and biological characteristics of the family Unionidae. The members of the family Unionidae are exclusively freshwater bivalves. Their external appearance is defined based on whether they live in rivers, streams or lakes. They have a specific life cycle in which the glochidia larvae have an essential developmental role. To develop into an adult mussel, glochidia must pass the parasitic stage on fish. Unionidae feed on bacteria and microfossil, and larvae glochidia on host tissue. By studying the topic, it was concluded that the family Unionidae are one of the oldest living organisms on Earth, and that is very threatened. Their vulnerability and reduced number is directly affected by various predators and people affecting the pollution of their habitats. Since the family Unionidae is threatened with extinction and holds great importance to the ecological system, it is necessary to ensure its survival.
