Gonadal development and sex differentiation in the cichlid fish Cichlasoma dimerus (Teleostei,
Perciforms): a light- and electron-microscopic study.
Monophyly of the Grammatidae and of the Notograptidae, with evidence for their phylogenetic positions among

* Stichaeid and pholid
perciforms (pricklebacks and gunnels) guard their egg masses by curling around them (Qasim, 1957; Hughes, 1986; Coleman, 1992).
Teleost fishes are represented by gadiforms, clupeiforms, oplegnathids, siluriforms,
perciforms, beryciforms, and chimaeriforms (see Table 2).
The orders with the most species are
Perciforms (15), Characiforms (9), and Siluriforms (5).
Mtochondrial molecular clocks and the region of euteleostean biodiversity: familial radiation of
perciforms may have predated the Cretaceous/ tertiary boundaary.
Perciforms were the dominant piscine prey; small amounts of amphipods and other pelagic crustaceans made up the remainder of the diet.
Characiforms (59%), Siluriforms (22%) y
Perciforms (12%) had the greatest richness.
Systematics of most families within Zoarcoidei, and of the suborder itself within the order
perciforms, is uncertain (Nelson, 1994).
Even more unfortunately, this includes the bulk of the marine
perciforms, which constitute much of the Philippine material.
