Living species range from the primitive jawless lampreys and hagfishes through the cartilaginous sharks, skates, and rays to the abundant and diverse bony fishes.
Há 2 dias · Extensive research has revealed a strong correlation between the endocrine system and skeletal development in various vertebrate species such as fish, amphibians, birds, and mammals. Specifically, changes in sex hormones and their receptors significantly impact the skeletal development of these vertebrate groups.

Há 2 dias · Vertebrate taxonomy is the branch of biology that focuses on the classification, naming, and categorization of vertebrate species. It involves the identification of similarities and differences between organisms and the organization of their relationships into a hierarchical system.
Há 2 dias · Across vertebrate species, the olfactory epithelium (OE) exhibits the uncommon feature of lifelong neuronal turnover. Epithelial stem cells give rise to new neurons that can adequately replace dying olfactory receptor neurons (ORNs) during developmental and adult phases and after lesions.
