no they have double loop circulatory system but the difference is that they have single ventricle.
open circulatory system
A circulatory system that involves the lungs is referred to as a double circulatory system. This is opposed to a single loop circulation that fishes have.
It's the simpler that exist in vertebrates that has gills as the site of gas exchange, wile other organism have a double loop circulatory system that have lungs instead of gills.
In most reptiles, the ventricle* is partially divided. This reduces mixing of oxygenated and unoxygenated blood in the ventricle.* = a.either of the two lower chambers on each side of theheart that receive blood from the atria and in turn forceit into the arteries. b.one of a series of connecting cavities of the brain.
Coral don't have circulatory systems. They just have a gastrovascular system!
single loop and heart with two chambers, like that of a fish.
the 3 fish classes
they have a single loop meaning the blood passes through the heart only once to go to everywhere in the body

Fish have a "single loop" circulation and Amphibians have a "double loop" circulation.
YES.
Fish have closed-loop circulatory systems.
