Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 13; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 11 - 12; गुदा कांटा: 2; ऐनल सौफट रेज़: 10 - 12.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adults occur near bottom over or near rocks, especially over steep banks, and also in kelp beds. Young school in open ocean. They retire to rocky holes at night (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Good eating.
