anatomy of bony fishes (Labelled and annotated diagram)
Cartilaginous and bony fishes Classify the following characteristics to describe the differences between cartilaginous fishes and bony fishes. Cartilaginous Fish Gills are covered with an operculum Skeletons are composed of bones Include gold fish, coelacanths, lion fish, and sea horses Bodies are covered with dermal denticles that project posteriorly Contain a closed single- loop circulatory system Have a lateral l ine system Bony Fish Include rays, sharks, and skates Skeletons are composed of cartilage Lack a gill cover May contain...
Briefly describe respiration in fishes. What adaptive mechanism increases efficiency? Diagram may help What is meant by "countercurrent flow" as it applies to fish gills? Compare the osmotic problem and mechanism of osmotic regulation in freshwater and marine bony fishes. Again diagrams may help.

Classify the following characteristics to describe the differences between jawless and jawed fishes. Some choices will be used to describe both groups. Jawed Fishes Gills present Cartilaginous endoskeleton nces Ectothermic Bony endoskeleton Jawless Fishes Have pectoral and pelvic fins controlled by muscles Scales present
