Single-loop circulation is primarily found in fish. In these vertebrates, blood flows in a single circuit: it is oxygenated in the gills and then distributed to the rest of the body before returning to the heart. This system is efficient for their aquatic environment but limits the metabolic demands that can be met when compared to the double-loop circulation seen in amphibians, reptiles, birds, and mammals.
Fish are vertebrates that have a single loop circulation system. In this system, blood flows in one continuous loop: from the heart to the gills for oxygenation, then directly to the rest of the body, and back to the heart. This type of circulation is efficient for their aquatic environment, allowing for effective gas exchange while maintaining a relatively simple cardiovascular structure.
Reptiles are animals. All animals in full activity need cellular respiration and all vertebrates I know of do that by means of circulation. Reptiles do circulate blood in their systems.
Whale sharks are vertebrates, but they have cartilage instead of bone. it depends and yes they are because they are a type of fish and fishes are vertebrates
fish
fishes do have parallel circulation
Vertebrates with hair, giving birth to live young, and that suckle their young are mammals.
Reptiles and amphibians are the vertebrates that have three-chamber hearts.
Vertebrates are animals within the phylum Chordata, that have a backbones (also called vertebrae).
