Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt) : 121 - 139; Afterflossenweichstrahlen: 91 - 102; Wirbelzahl: 71 - 78. This species is distinguished by the following set of characters: dorsal-fin rays 121-139; anal-fin rays 91-102; total vertebrae 71-78; otolith ostium depth 30-40% of sulcus length (Ref. 80689).
One specimen from the eastern Pacific was examined and radiographs showed the following stomach contents: detritus, gastropods, crustaceans, ophiurids, remains of polychaetes, foraminifera, sediment, and bivalves. From individuals with filled stomachs), detritus was found to be 88%, followed by gastropods (52%), crustaceans (44%), and ophiurids (36%). Observed ontogenetic trend in the consumption of gastropods with 18.2% in specimens less than 45 cm SL (n=11) and 78.6% in specimens greater than 45 cm SL (n=14, Fisher’s Exact Test, P<0.005); all gastropod shells were intact (Ref. 80689).
