आकार / वज़न / Age
परिपक्व अवधि: Lm ? range ? - ? cm
Max length : 11.3 cm TL पुल्लिंग / अलिंग; (Ref. 4996)
पृष्ठीय रीढ़ (सम्पूर्ण) : 16 - 17; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 10 - 11; गुदा कांटा: 3; ऐनल सौफट रेज़: 9 - 10; जानवरों की रीड़ का जोड़: 31. Resembles P. fenestratus in form and in ecology, but differs from it in having a larger eye and consequently narrower preorbital, in the more numerous teeth in the upper jaw and on the lower pharyngeal, the higher number of gill rakers, the anterior of which, although short, are acute and well defined and in the higher modal number of dorsal spines. Differs from P. virgatus in the absence of enlarged pharyngeal teeth.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Inhabits shallow, rocky sediment-free habitat. Feeds on 'aufwuchs' attached to rocks, but also takes small invertebrates, including zooplankton when this is abundant (Ref. 267).
Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | अंडे | Fecundity | लार्वा
Parents practice co-operative care of young by grouping together and setting up protective stations close to one another; releasing their young and embarking upon parental care. Every protective mantle is very close to the next in such a way that young can move from one parent to the next.
