Distribution


Description

One of the more colourful Nesogobius species, hence easily distinguished from the others. Base body "colour" is translucent, with alternating red and white dashes mid body, silvery spots or blotches below, sometimes smaller red and silvery-white spots above, short diagonal yellow lines or marks on lower head and operculum, usually a small yellow/brown spot on pectoral fin base, white iris. Vertical groove in operculum not obvious to divers.

Currently referred to in the literature as 'Nesogobius sp. 4 Groovedcheek Sandgoby', it can be common in its range, but is yet to be formally described (along with several other Nesogobius species).


Information

Max Size: N/A cm

Sea Temperature Range: N/A

Depth: N/A

Habitat Generalization Index: N/A

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Vulnerable

Occurrence: Frequent (10.8% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Not determined

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
