Flashcards in Chapter 13 (percomorpha) Deck (24):
1

Describe the lampriformes

large, offshore, highly colored fishes of striking form. All are marine, rather deep water. closed gas bladder. pre max and maxilla are freely protractile.

3

Order Beryciformes

no relatable taxa, just that they appear to be less derived than perciformes

4

Gasterosteiformes: what connects most groups?

elaborate male parental care of young

5

why are synbranchiformes only eel-like superficially?

highly evolved air breathers, tripical and subtropical freshwater fishes. Also, it has one continuous gill slit, not two.

6

Name the 6 scorpaeniform suborders

scorpaenoidei
platycephaloidei
anoplopomatoidei
hexagrammoidei
cottoidei
dactylopteroidei

7

how are the scropaeniformes clumped together?

relationship is unknown. the Suborbital Stay is the only thing.

8

what is the Suborbital Stay?

a bone connecting all of the scorpaeniformes together, a posterior connection to the third circumorbital bone (SO3)

9

generalized percaform morphology

spines in fins: present
Dorsal fins: 2, never adipose
Scales: Ctenoid or absent
Pelvic fin placement: thoracic or jugular
swimbladder: physoclists

10

What suborder of Perciformes has the 10 largest families?

Percoidei
(includes serranidae, apogonidae, scaienidae, percidae, haemulidae, carangidae, chaetodontidae, pseudochromidae, sparidae, lutjanidae).

11

what is to be said of the Percoidei in regards to future evolution?

The percoidei seems to be the basal evolutionary group from which other suborders have been derived. also, there are two perform derivative orders.

12

what determines the difference between sinistral and dextral starry flounders?

genetic control

13

what bony parts have been lost in Tetradontiformes?

lack parietals, nasals, circumorbitals. lower ribs.
