Chirocentrodon bleekerianus (Teleostei: Clupeiformes: Pristigasteridae), a small predaceous herring with folded and distinctively oriented prey in stomach

Abstract: Predaceous fish-eating species of the order Clupeiformes have a large mouth with well-developed teeth, and reach the greatest sizes within their families (up to 90 cm). We found that the pristigasterid Chirocentrodon bleekerianus, a small clupeiform (about 10 cm) from the tropical SW Atlantic, is able to prey on proportionally large clupeoid fishes and caridean shrimps. Fish preys are folded in the stomach of this herring, their heads and tails pointing toward the predator's head. This distinctive orientation … Show more

“…Compelling evidence against the role of feeding‐related constraints in the shaping of bones of the suspensorium of the Chirocentridae and Engrauloidea is found in the pristigasteroid Chirocentrodon bleekerianus . Like the Chirocentridae and primitively in the Engrauloidea, the carnivorous C. bleekerianus feeds on relatively large fishes, such as other clupeoids and shrimps up to 50% its own standard length (SL) (Sazima, Moura & Sazima, 2004; Corrêa, de Tarso Chaves & Guimarães, 2005). The Chirocentridae and C. bleekerianus share the presence of canine‐like and relatively well‐developed teeth, and the separation of the dorsal paired elements of their branchial arches among other general anatomical features presumably related to a predaceous diet.…”

“…The fact that first order carnivores had shown high density at night is mainly associated with L. breviceps and C. spixii, which were the most abundant species during this period. C. bleekerianus is a piscivore or third order carnivore as adult, feeding mainly on small fish (Sazima et al, 2004;Corrêa et al, 2005). Based on the length of first sexual maturity (76 mm) (Corrêa et al, 2005), 90% of C. bleekerianus sampled was composed of adults.…”

“…A espécie C. bleekerianus se alimenta principalmente de crustáceos copépodes e sergestídeos, e as larvas e juvenis de peixes (Engraulidae e Clupeidae) também fazem parte da sua alimentação (SAZIMA et al, 2004;CORRÊA et al, 2005;MUTO et al, 2008). Devido à presença de dentes bem desenvolvidos, essa espécie pode se alimentar de peixes juvenis que alcançam até 50% do seu tamanho corporal (SAZIMA et al, 2004). Em relação a P. harroweri, Criales-Hernadéz (2003) e Muto et al (2008) relatam a presença de crustáceos copépodes, ostracodes e decápodes como principais itens da dieta.…”
