Is osteichthyes a ectothermic class?
Osteichthyes, or bony fish, are ectothermic, meaning they are cold-blooded.
Is the class chondrichthyes endothermic or ectothermic?
Endothermic or no? Chondrichthyes, section "Metabolism" says: "Chondrichthyes are ectothermic or cold blooded, meaning they do not have to warm themselves through eating.
Are class Aves ectothermic?
Reptiles and amphibians are ectotherms, while birds are endotherms. An ectotherm (reptile/amphibian) relies primarily on its external environment to regulate the temperature of its body. Endotherms (birds) are able to regulate their body temperatures by producing heat within the body.
How do Agnatha eat?
It has a ring of tentacles around its mouth that it uses to feel for food. It has a tongue-like projection that comes out of its jawless mouth. At the end of the projection are tooth-like rasps that close when the "tongue" is pulled back into the hagfish's mouth. The hagfish eats marine worms and other invertebrates.
Are lampreys endothermic?
lampreyectothermic fish with a partial backbone; does not have jaws; skeleton is made of cartilage.
Do bony fish have backbones?
Fish are vertebrates which means they have vertebrae . A bone structure that makes up the vertebral column (backbone). ... The first is a skeleton structure made up of cartilage, as in cartilaginous fish, the other is bone found in bony fish. Both types have a vertebral column (backbone).
How are vertebrates classified?
Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. Amphibians, reptiles, birds, and mammals are ranked as classes. ... For example, there are some groups that do not consider Hyperoartia to be a class, but rather consider to to be a currently unranked group.
How do Agnatha breathe?
“Water breathing” through gills which are modified pharyngeal slits. (gas exchange between water and blood). Gills can absorb lower concentrations of available oxygen.
What animals are endothermic?
Endothermic animals are animals that are able to maintain a constant body temperature regardless of their ambient temperature. Endothermic animals include all birds and mammals of the animal kingdom. Even some fish are considered to be endothermic.
What are the 5 classes of vertebrate?
The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds. Show examples of these groups and explain the characteristics that make one different from another.
Are snakes endothermic?
Snakes are reptiles and all reptiles are ectothermic (ecto = from the outside, thermic = temperature). This means that they obtain body heat from their environment. Mammals, such as humans, are endothermic (endo = from the inside, thermic = temperature) or warm-blooded.
What type of consumers are Agnatha?
what type of fertilization do agnathans exhibit? What type of consumers are lampreys? Parasitic.
Are Agnatha warm or cold blooded?
All living and most extinct Agnatha do not have an identifiable stomach or any appendages. Fertilization and development are both external. There is no parental care in the Agnatha class. The Agnatha are ectothermic or cold blooded, with a cartilaginous skeleton, and the heart contains 2 chambers.
