Perciformes
Sign in to savePerciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. Perciformes means "perch-like". Among the well-known members of this group are perches and darters (Percidae), and also sea basses (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean.
AI overview
Perciformes is a large group of ray-finned fish that includes familiar species like perches, darters, and sea basses, and gets its name from its resemblance to perches. This order is significant because it contains fish adapted to nearly every aquatic environment on Earth, from polar regions to the deepest ocean depths, as well as freshwater and tropical seas.

Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. Perciformes means "perch-like". Among the well-known members of this group are perches and darters (Percidae), and also sea basses (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean.
== Taxonomy == Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as the Scorpaeniformes, are now classified in the Perciformes.
