Description

A medium sized, short-necked freshwater turtle. It is brown above, but is usually quite bright yellow below, except in large older individuals. Usually a distinct yellow stripe from the angle of the jaws, especially in the young, while the underside of the tail has distinctive yellow markings. For detailed description see Cann (1998), Cogger (2014) and Cann et al. (2015). The species was previously known as Elseya purvisi, E. latisternum and is referred to as Wollumbinia purvisi in some publications.

Distribution

Endemic to the middle and upper reaches of the Manning River catchment area. Its distribution is inferred to be severely fragmented and highly restricted. Lack of targeted surveys in the more remote and inaccessible upper catchments means the habitat value of upper catchment areas is unknown, as is the presence of this species in conservation reserves.

Habitat and ecology

  • Habitat preference is for relatively shallow, clear, continuously fast-flowing rivers with rocky and sandy substrates (Wells 2002).
  • Boulder beds in pools 2-3 m deep and submerged logs are used as shelter sites by individuals or small aggregations of turtles (Wells 2002).
  • The species is predominately diurnal, often seen basking on logs, rocks or the river banks near deep pools, although nocturnal foraging in shallow areas has been observed (Wells 2002).
  • It is apparently omnivorous (Allanson and Georges 1999; Wells 2002) but lacks the ability to catch fast moving prey, instead foraging on the benthos for less mobile food such as other macro-invertebrates, terrestrial fruit and aquatic vegetation (Allanson and Georges 1999).
