Notiocampus

Notiocampus ruber, known commonly as the red pipefish, is a species of pipefish endemic to the temperate waters along the southern coast of Australia, including Tasmania. It occurs at depths from 5 to 20 m (16 to 66 ft) over the continental shelf. This species grows to a length of 16.4 cm (6.5 in) and is the only known member of its genus. N. ruber is a historically understudied species, with fewer than 12 records nationally prior to 2021, and its reproductive morphology and phylogenetic placement remained unresolved for more than four decades after the genus was described by C. E. Dawson in 1979.

Distribution and habitat

Notiocampus ruber has a broad but sparsely recorded distribution across temperate southern Australia, ranging from New South Wales to Western Australia and including Tasmania. Records are primarily from reef crevices and hard substrates at depths of 5 to 20 m (16 to 66 ft). Observations from Gamay (Botany Bay), New South Wales, between 2017 and 2021 documented individuals at approximately 12 m (39 ft) depth in mixed habitats comprising sand substrates and low-relief hard structures, frequently among feathery red macroalgae. The first known photograph of a living specimen was taken on the Fleurieu Peninsula, South Australia, in 2007–2008.

Individuals are typically observed alone or in pairs, though aggregations of multiple individuals have been recorded. At least one individual exhibited short-term site fidelity, being repeatedly observed at the same location over a six-month period.
