Population [top]

Population:Hubbs (1953) reported that Neoclinus uninotatus is "not common anywhere in its range", however Eschmeyer and Herald (1983) state that this species is easily seen around coastal structures such as piers.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Neoclinus uninotatus is found over sandy and muddy substrates along rocky coastlines and bays.  It is often found sheltering in rocky crevices and man-made objects such as tires and bottles and is exceedingly territorial (Eschmeyer and Herald 1983).  Both sexes tend the eggs.  This species is found at depths of 3–27 m.

Threats [top]

Major Threat(s): It is unlikely that Neoclinus uninotatus is being impacted by any major threat processes.  This species appears to be relatively tolerant to disturbance, as it is often found in areas where coastal development has taken place and in areas littered with rubbish.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for Neoclinus uninotatus, however in places, its distribution may coincide with marine protected areas.
