“…Characters of the PJA do not appear to be accurate markers of labroid evolution, although convergence in this functional complex is no less exciting. Because other perciform fishes share pharyngeal characters with the labroids, it has been suggested (Liem & Greenwood 1981;Nelson 1967;Stiassny & Jensen 1987) that labroid families are part of a larger pharyngognathous assemblage. It could be argued that a proper test of labroid monophyly should include fishes from other families thought to be pharyngognathous teleosts (e.g.…”

“…Perciform fishes possessing a 'crushing' pharyngeal bite have been accorded natural group status since the work of Müller and Cuvier in the 1880s (Rosen & Patterson 1990). Cuvier's arguments about the pre-eminence of function over form (Rieppel 1990) have sculpted neo-Darwinian concepts of evolution and fostered a functional approach to systematics (Kaufman & Liem 1982;Lauder & Liem 1983;Liem & Greenwood 1981). Recently, molecular and analytical advances have permitted the evaluation of functional morphological evolution using phylogenies independent of focal characters (Albert et al 1992;Cunningham et al 1992).…”

SUMMARYFifteen per cent of all living fishes are united in a single suborder (Labroidei) and display a dazzling array of behavioural and ecological traits. The labroids are considered monophyletic and members share a pharyngeal jaw apparatus (PJA) modified for crushing and processing prey. Outside of the explicitly functional PJA, there is no corroborative evidence for a monophyletic Labroidei. Here, we report the first molecular phylogenetic analysis of the suborder. Contrary to morphology-based phylogenies, our single-copy nuclear DNA data do not support labroid families as a natural group. Our data indicate that pharyngognathy has evolved independently among labroid families and that characters of the PJA are not reliable markers of perciform evolution. This work 'crushes' conventional views of fish phylogeny and should engender novel concepts of piscine life history evolution.

“…This strategy may not be effective or possible until the buccal cavity of a fish attains a certain size and associated structures fully develop. Liem and Greenwood (1981) argued that Embiotoca, despite marked specializations in jaw morphology, are capable of a wide range of feeding actions. Our field observations of adult E. jacksoni confirm that substantially different foraging behaviors are used interchangeably by all individuals during a single foraging bout.…”

Proximate mechanisms leading to similarities and differences in diets of juvenile and adult black surfperch Embiotoca jacksoni in populations at Santa Catalina Island (USA) were explored. These fish are microcarnivorous, harvesting invertebrate prey primarily from benthic turf and foliose algae. Ontogenetic differences in prey size ultimately reflect age-specific differences in size of fish. Young juveniles are apparently gape limited and use a visual picking mode of foraging. This strongly influences the array of algal substrates from which prey can be effectively harvested. Turf substrates are used extensively by older fish that employ winnowing behavior to separate prey from debris. The ability to winnow develops slowly during the first year of life and allows exploitation of turf, a preyrich, extensive resource base. The marked differences in body size and foraging behavior have only a relatively small influence on the gross taxonomic makeup of the diets of black surfperch.

“…They have oral jaws, used primarily to capture prey (Schaeffer and Rosen 1961), and also modified gill arches called pharyngeal jaws that are used to crush, shred, and prepare prey for digestion (Schaeffer and Rosen 1961;Liem 1973). Primitively, fish oral jaws were used extensively in prey processing, but during teleost evolution, clades have sequentially arisen that exhibit greater elaboration of the pharyngeal jaw (Liem and Greenwood 1981;Lauder 1985). As the ancestral condition of simple toothed pharyngeal processes found in basal teleosts was transformed into the sophisticated and highly articulated perciform apparatus during evolution, this has putatively resulted in increased power and effectiveness for processing prey (Liem 1973).…”
