Siphonognathus beddomei
Pencil weed whiting
Similar Species
Distribution
Temperate Australasia
Description
Extended body like the slender rock whiting, but the snout is long and pointed. The sides of the body generally carry thin blue stripes that are particularly conspicuous during the breeding season. Small aggregations of this species are very common above beds of Phyllospora comosa and other large brown algae on wave exposed reefs, but divers rarely notice these animals because of their small size.

Conservation and Rarity
IUCN Status: Least Concern
Occurrence: Common (38.1% 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: Several (7 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
