Bodianus dictynnaRedfin hogfish | Pacific Diana's Hogfish | Pacific Diana's Pigfish
Temperate Australasia, Temperate northern Pacific, Tropical Indo-Pacific
Adults virtually identical in appearance to B. diana (Diana's Pigfish) but recently described as a separate species. Best distinguished on basis of location (B. dictynna Pacific Ocean only), although juveniles have slightly different spot patterns on the head. B. diana has more light spots on the snout and more distinct spots behind the eye, while many of the spots behind the eye are fused to form elongated markings in this species.
Max Size: 16 cm
Sea Temperature Range: 28.7-30.4°C
Habitat Generalization Index: 2.42
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: Least Concern
Occurrence: Frequent (11.9% 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: Few (3 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
