More Info


Distribution

Known only from continental shelf waters of the Timor Sea NNE of Cartier Island, off northwestern Western Australia, depth 95 m.
This species was collected in a beam trawl with coral,  sponges,  urchins, and abundant red algae (which may have provided shelter).

Features

Dorsal fin IX spines as VIII-I, 9 or  VII(I)-I, 9; Anal fin II, 8: Pectoral fin 16; Pelvic fin I, 5; Principal caudal-fin rays 1+8-7+1; Gill rakers 14(14-15); Vertebrae 10+14; Branchiostegal rays 7. In the dorsal-fin spine formula, the spine inside parentheses refers to a spine hidden below the skin.

A small species of Apogonichthyoides with 9 visible dorsal-fin rays, a reddish head and body in life with a dark spot on the body above the pectoral fin, 16 pectoral-fin rays, 7-8 well-developed gill rakers on first arch, 2-3 rows of palatine teeth and a rounded caudal fin (Fraser 2010).

Size

To 36.5 mm SL, 47 mm TL.

Colour

Head, body and fins reddish, with a broad pale band under the eye, and a round non-ocellate black spot behind the gill cover above the pectoral fin, followed by three evenly-spaced faint dark marks along the midline; first dorsal fin with black membranes between the 3rd and 6th spines; pelvic-fin rays reddish with blackish tips; anal fin pale near base, reddish distally; caudal fin with a pale area near base followed by a wide reddish band and a pale margin.

Feeding


Biology

The sexes are separate and fertilisation is external. Males brood the developing eggs in their mouths. One female (32.2 SL) contained eggs ~0.4 mm diameter. One mouth-brooding male, 34.4 SL, had eggs ~0.7 mm diameter in its mouth.

Fisheries

Of no interest to fisheries.

Conservation


Remarks

Apogonichthyoides miniatus is only known from 27 specimens collected from a depth of 95 metres in the timor Sea near Cartier Island. The same collection contained abundant red algae that may have provided habitat cover for this species and several other small red fish species.

Similar Species

Differs from all other known species of Apogonichthyoides in having the following combination of characters: small size; reddish head, body and fins; rounded non-ocellate black spot on the body above the pectoral fin followed by three faint midline darkish marks; low gill raker counts (14-15); high pectoral fin-ray counts (16); rounded caudal fin.

Etymology

The species name miniatus is Latin meaning 'bright red' or 'cinnabar-red' for the reddish coloration of the head, body and fins.
