Summary:

A small sandy-coloured ambush predator with the body flattened anteriorly, eyes close together on top of head,  a large mouth, long-based dorsal and anal fins and large pectoral fins. The cirri fringing the mouth prevent sand entering the mouth when Flathead sandfish is buried.

More Info


Distribution

Endemic to temperate marine waters of Australia from Fraser Island (Queensland) to about Geraldton (Western Australia), including around Tasmania, Although rarely seen due to their excellent camouflage, Flathead Sandfish inhabit the surf zone of sandy beaches in coastal waters, bays and estuaries, at depths to 20 m.

Features

Dorsal fin 32-36; Anal fin 36-37; Pectoral fin 17-21; Pelvic fin I, 5; Caudal fin 10; Lateral line 46-49.

Head depressed, body depressed anteriorly, top of head slightly convex to flat in profile, eyes on top, close together; mouth large, directed slightly upwards when closed, lower jaw projecting slightly beyond upper. Mouth surrounded by many cirri. Scales covering most of head, scales absent from front of pectoral-fin base.

Size

To a standard length of 11 cm.

Colour

Sandy coloured, scales outlined in pale green, grey or brown on top, underside pale. Individuals are coloured to match the sandy bottom on which they live.

Feeding

Flathead sandfishes are not only well-camouflaged, but also hide from predators and prey by bury in sand leaving only their eyes exposed. These ambush predators feed on small bony fishes and invertebrates.

Biology

The sexes are separate and fertilisation is external. Larvae are described by Neira (1998).

Fisheries

Of no interest to fisheries.

Etymology

The genus Lesueurina is named in recognition of Charles Lesueur's work as an ichthyologist at the Academy of Natural Sciences of Philadelphia. The specific name platycephala is from the Greek platys (= flat) and kephale (= head) in reference to the flattened head of this species.
