consequently it is rarely caught by anglers. Flesh good.
Known only from False Bay to Maputo in 20 - 200 m.
188.1 Paraseorpis typus: 35 em SL (Port Alfred).
Family No. 189: KYPHOSIDAE

Sea chubs
See-vetsakke
Body oval, with small, weakly ctenoid scales covering
head, body and fins; mouth small; maxilla scaly; outer
series of incisors with long roots in jaws and fine teeth
within jaws, on palate and sometimes on tongue. Single
dorsal fin with 10 or 11 spines and 11-15 soft-rays; anal fin
with 3 spines and 11-14 soft-rays. Gasbladder divided behind, extends into tail.
Moderate-sized fishes of shallow water about rocks and
reefs; feed mainly on algae and associated small creatures.
Flesh not highly esteemed. Three genera, the 2 monotypic
genera Hermosilla Jordan & Evermann, 1889 and Sectator
Jordan & Fowler, 1893 from the Pacific differ from
Kyphosus in the naked interorbital and edentate tongue of
the former, and elongate body and small incisiform teeth
with inconspicuous roots of the latter.
Genus Kyphosus Lacepede, 1801
Circumglobal in warm water; contains about 7 species,
3 in our area.
