2021年2月13日 · Any vertebrate, classified under subphylum Vertebrata, is an animal with a backbone. This group consists of several broad classes: fish, amphibians, birds, reptiles, and mammals. The word vertebrate refers to the bony vertebral column.

The vertebrates make up the subphylum Vertebrata with some 65,000 species, by far the largest grouping in the phylum Chordata. The vertebrates include mammals, birds, amphibians, and various classes of fish and reptiles. The fish include the jawless Agnatha, and the jawed Gnathostomata.

Vertebrate, any animal of the subphylum Vertebrata. They have backbones and are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone. Its members include fishes, amphibians, reptiles, birds, and mammals.

2022年6月29日 · The five main groups of vertebrates are fish, amphibians, reptiles, birds, and mammals. There are actually more categories, since bony fish are separate from jawless fish (lampreys and hagfish), cartilaginous fish (sharks and …

1 天前 · The Journal of Vertebrate Biology (formerly Folia Zoologica, founded in 1938) publishes high-quality original research papers of broad interest. The Journal welcomes hypothesis-driven papers on the behaviour, ecology, physiology, anatomy, developmental biology, taxonomy, and evolution of vertebrates, including research at the interface of these ...

2024年11月23日 · Vertebrates are the largest group of chordates, with more than 62,000 living species. Vertebrates are grouped based on anatomical and physiological traits. The traditional groups include Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia.

Vertebrates are among the most recognizable organisms of the animal kingdom (Figure 1). More than 62,000 vertebrate species have been identified. The vertebrate species now living represent only a small portion of the vertebrates that have existed.
