Australian Lungfish [Ceratodontidae]

Description

Ceratodontidae is a family represented by a single species, the Australian lungfish (Neoceratodus forsteri), also known as the Queensland lungfish. Found in the Mary and Burnett River systems in Queensland, Australia, these lungfishes prefer slow-moving rivers and still waters. Unlike their South American and African relatives, Australian lungfishes have a more conservative morphology, retaining features that closely resemble the ancient lungfishes of the Devonian period. They have large, paddle-like pectoral fins and a dorsal fin that runs along the length of their body. Australian lungfishes are less dependent on air-breathing and have both gills and a single lung, allowing them to breathe underwater and surface for air when necessary. Their diet includes a variety of aquatic plants, invertebrates, and small vertebrates. The Australian lungfish is a significant species due to its evolutionary importance and is considered a living fossil.
