Oxeye Scad, Selar boops (Cuvier 1833)
More Info
|
Distribution |
Kendrew Island, Western Australia, around the tropical north to about Townsville, Queensland. Elsewhere the species is widespread and common in the tropical, Indo-west-central Pacific (one record from east Atlantic) in depths to 500m. The Oxeye Scad is pelagic in coastal waters, often over soft bottom areas or seagrass beds and occasionally rocky and coral reefs. Individuals form large dense schools during the day, and disperse to feed at night. |
|
Features |
Dorsal fin VIII + I + 23-25; Anal fin II + I + 19-21; Gill rakers (including rudiments) 8-10 upper, 25-29 lower (first gill arch); Lateral line 21-24 scales + 0-4 scutes (curved part), and 37-46 scutes (straight part). Teeth small, recurved, those of upper jaw in a narrow band, tapering posteriorly; lower jaw with an irregular single row of teeth. Shoulder girdle (cleithrum) margin with two papillae: a relatively large papilla ventrally and a smaller papilla near upper edge. Spinous dorsal fin relatively high, longest spine about equal to length of soft dorsal fin lobe. Lateral line curving steeply downward below origin of soft dorsal fin, with straight row of scutes extending for more than half body length. |
|
Feeding |
Feeds at night on planktonic and benthic crustaceans (crabs and shrimps) and small fishes. |
|
Fisheries |
Fished commercially in parts of its range. |
|
Remarks |
Selar boops co-occurs with the Bigeye Scad, Selar crumenophthalmus in northern Australia. |
|
Similar Species |
The similar Bigeye Scad, Selar crumenophthalmus, differs in having 48–56 scales in the curved part of the lateral line (vs. 21–24 scales in S. boops), moderate sized scutes on the caudal peduncle (vs. large scutes) and the curved part of lateral line roughly equal in length to the straight part, 0.7 to 1.2 times in straight part (vs. 2.1 to 3 times in the straight part). |
|
Etymology |
The specific name boops is from bo (= ox) and ops (= eye) in reference to the large eyes of this species (Scharpf & Lazara 2020). |
