Summary:
A pale comb-tooth blenny with sparse fine dark spots peppering the rear of the body, a dark Y-shaped or forked mark on the fleshy pectoral-fin base, a black lower lip and black "chin-strap", and an indistinct dark stripe running from the rear of the eye to above the gill cover.

More Info

Distribution |
Northern Great Barrier Reef and reefs in the Coral Sea, to about Moreton Bay, Queensland. Elsewhere the species occurs in the east-Indo-west-central Pacific. Inhabits shallow reefs, often perching on coral heads in lagoons and reef flats, at depths to 11 m - usually in areas not exposed to heavy surge. |
|
Features |
Dorsal fin XII-XIII, (rarely XIII), 13-15; Anal fin II, 15-17; Pectoral fin 12-14 (rarely 12 or 14); Segmented caudal-fin rays 13; Vertebrae 10 + 21-23. Dorsal fin deeply incised between spinous and segmented-ray areas. Dentary incisor teeth which includes anterior canines very similar in appearance from incisors, 46-54 in males and 48 to 56 in females, averaging more in females than males; posterior canines 0 or 1 (usually 1). Lateral line without vertical pairs of pores, extending posteriorly to point between vertical from interspace between 9th and 10th spines and vertical from base of 11th dorsal-fin spine (rarely anterior to base of 10th spine). With cirrus on posterior rim of anterior nostril; absent on anterior rim. |
|
Colour |
Body pale with a distinct, dark Y-shaped mark on the fleshy pectoral-fin base, a black "chin-strap", fine dark spots sparsely peppering the rear of the body, a dark horizontal stripe from the rear of the eye above the gill cover, a dark lower lip followed by a conspicuous pale salmon-pink area on the chin and a dark dusky area behind. The fine dark spots are aligned, more or less, in two or three rows, and may be continuous with dark dash-like marks anteriorly on the body. |
|
Biology |
Females lay demersal eggs that are attached to the bottom via a filamentous, adhesive pad or pedestal. The larvae are planktonic, often found in shallow, coastal waters. |
|
Fisheries |
Semi-translucent grey body, pale orange eyes, black ‘chinstrap’, dark V-shaped mark on pectoral fin base, faint spots and dashes in rows along body, and fine black spots scattered on rear half of body. Also has a darker colour form with a more heavily patterned body, black spots on rear of body are still present though. |
|
Remarks |
Small family groups usually live atop large bommies and coral heads, perching on their pectoral and pelvic fins when not feeding. |
|
Similar Species |
The similar Palespotted Combtooth Blenny Ecsenius yaeyamensis, also has a dark Y-shaped dark mark on the fleshy pectoral-fin base, and has larger white spots on the body rather than fine black spots, along with distinct black dashes behind the eye. |
|
Etymology |
The specific name is from the Greek stictus (= spotted), in reference to the fine dark spots on the body that distinguish the species. |
