More Info


Distribution

Port Stephens to Botany Bay, New South Wales, also Lord Howe Island in the Tasman Sea. Elsewhere the species occurs in Hawaii, Midway Island, northern New Zealand, and possibly the Seychelles.
Inhabits sand areas associated with rocky and coral reefs at depths of 7-293 m.

Features

Fins absent. Body very elongate; tail 2.1–2.2, head 17–21, body depth 43–66 in total length; 3 preopercular pores and 3 pores in supratemporal canal; teeth conical, uniserial on jaws and vomer; 1–2 vomerine teeth; body coloration light tan with numerous minute brown to dark brown spots on head, body and tail, with a faint white slash angling behind eye to behind jaw corner; and MVF 77–158, total vertebrae 154–166 (n= 20).

Size

An elongate species with: tail 1.8–2.2, head 18–20, and body depth 67–83 in total length; snout sharply pointed in lateral view; 3 preopercular pores and 3 pores in supratemporal canal; teeth conical, uniserial on jaws and vomer; 5–10 vomerine teeth; body mostly pale in preservative, creamy dorsally and reddish-brown ventrally with light and dark head markings in life; and MVF 82–164, total vertebrae 162–167 (n= 14)

Remarks

This species is easily confused with the very similar Apterichtus australis (see McCosker & Hibino 2015).

Etymology

The specific name flavicaudus is from the Latin flavus, meaning 'yellow', and caudus, meaning 'tail', in reference to the lemon yellow colour on the posterior half of the body.
