Dispersion

Halichoeres leucurus lives in the Western Pacific, specifically from the Philippines to New Guinea and from the Yaeyama Islands to southern Indonesia.[2]

Biology

Halichoeres leucurus can be found in coral-rich lagoon and inner channel reefs 1–15 meters deep in mixed coral and algae habitats. These fish may be found solitary or in pairs. They feed on small benthic invertebrates like nematodes, flatworms, gastrotichs, freshwater mussels, oligochaetes, and some amphipods.[3]

Description

They have 9 dorsal spines, 13 Dorsal soft rays, 3 anal spines, and 13 anal soft rays. Males are recognized by the grey head when seen in natural light. Body has a lined pattern until female stage. Males have orange spots along scale rows.[2]

gollark: *Ideally*, at least, school works as a place to learn things from those who know them well and discuss it with interested peers.
gollark: Unfortunately, this is implemented poorly.
gollark: I don't really agree. It is not practical to guess what directly applicable skills will be needed in the future. It should teach general skills like learning independently fast, mathematical modelling, useful writing, languages, and that sort of thing.
gollark: It's actually possible to learn things yourself.
gollark: CVs are maaaybe suitable for teaching since I don't think there's that much to it but you can probably learn faster with good feedback.
