Feeding with speed: prey capture evolution in cichlids

Popis výsledku v původním jazyce

The diversity of both the locomotor and feeding systems in fish is extensive,although little is known about the integrated evolution of the two systems. We have used phylogenetic-independent contrasts to study the relationship between the predator closing speed(RS) and mouth size (MG) during prey capture in 18 species of neotropical cichlids. High-speed digital video camera was used to study the prey capture sequences. To provide a robust comparative framework, we augmented existing phylogenetic information available from the mitochondrial cytochrome b gene with sequences from the S7 nuclear ribosomal intron for these species. Our finding is that RS is positively correlated with mouth size. We predict that species that are more flexible with regard tothe accuracy required during a feeding strike, because of their ability to exhibit a larger gape, will generally exhibit greater attack speeds.
