Where are we Taxonomically?

Subdivision: Euteleostei

Superorder: Acanthopterygii

Series: Percomorpha

Order: Perciformes

slide2

Percomorpha, part II

Suborder Percoidei continued…

Haemulidae: grunts

Haemaleos = bloody (G)

Pomacanthidae: angelfishes

Toxotidae: archerfishes

pom (G) = opercle (cover) acanth = spine

toxo (G) = bow

slide3

Percomorpha, part II

(Suborder)Labroidei

Cichlidae: cichlids

More than 1300 species, tremendousdiversity in morpholgy and ecology

Many are convergent with centrarchids

Look for single nostril and

distinctive broken lateral line

Pomacentridae: damselfishes

Poma- = opercle, centron = spine (G)

(refers to pointed margin of opercle)

slide4

Percomorpha, part II

(Suborder)Labroidei

Scaridae: parrotfishes

Labridae: wrasses

labrum = lip or edge (L)

Latin, sacrus = a fish described by ancient writers; 1601. Derived from Greek, skairo = to jump; due to the legendary jumps and tail bumps, very well known by ancient fishers

slide5

Percomorpha, part II

Blennioidei

Blenniidae: combtooth blennies

blennos = similar to mucus; also a kind of fish applied to a species of ray. (g)

Gobiesocoidei

Gobiesocidae: clingfishes

gobius = goby (l) + esox = nursery of salmon (g)

slide6

Percomorpha, part II

Gobioidei

Gobiidae: gobies

Acanthuroidei

Ephippidae: spadefishes

ephippium = Saddle, similar in shape to

a depression of the sphenoid bone

slide7

Percomorpha, part II

Acanthuroidei

Siganidae: rabbitfishes

siganus = rabbit fish,

by the similarity of the nose (L)

Acanthuridae: surgeonfishes

akantha = thorn + oura = tail (G)

slide8

Percomorpha, part II

Scombroidei

Sphyraenidae: barracudas

Greek, sphyraina = a fish similar to

an iron pin, a pike like fish

Trichiuridae: cutlassfishes

trich (G) = hair

ur (G) = tail

Scombridae: mackerels, tunas scomber = mackerel (L)

slide9

Percomorpha, part II

Scombroidei

Premaxilla and nasal bones produced, forming a spear-like bill or rostrum with a rounded cross-section.

Gill membranes not united to isthmus.

Very narrow pelvic fins.

Jaw teeth present.

Two keels on each side of caudal peduncle in adults.

Dorsal fin extending over much of bodylength, sometimes resembling a sail.

Dorsal fin can be depresssed into a groove.

Lateral line persists in life.

Vertebrae 24.

Maximum length 4 m.

Istiophoridae: billfishes

istion = sail + pherein = to carry (G)

slide10

Percomorpha, part II

Anabantoidei

Gouramis:

Belontiidae/ Osphronemidae

Pelvic fins have elongated ray

osphra, -as = smell + nema = filament (G)

slide11

Percomorpha, part II

Pleuronectiformes

pleuro (G) = side, nect (L) = bound

Bothidae: left-eye flounders

Pleuronectidae: right-eye flounders

Soleidae: Soles

Cynoglossidae: tongue fishes

cyno (G) = dog, gloss (G) = tongue

slide12

Percomorpha, part II

Tetraodontiformes

Balistidae: triggerfishes (balist = catapult)

Ostraciidae: box fishes, cowfishes, trunkfishes

ostrac (G) = shell

slide13

Percomorpha, part II

Tetraodontiformes

Tetraodontidae: puffers

tetr (G) = four

odont (G) = teeth

Diodontidae: porcupinefishes, burrfishes

slide14

Percomorpha, part II

Tetraodontiformes

Molidae: ocean sunfishes

mola = millstone, by the shape of this fish
