Research news on ichthyology

Ichthyology is the branch of zoological sciences devoted to the systematic study of fishes, encompassing their taxonomy, phylogeny, morphology, physiology, development, behavior, ecology, and biogeography. It addresses both extant and extinct fish lineages, integrating molecular and morphological data to resolve evolutionary relationships and classification. Ichthyological research underpins understanding of aquatic ecosystem structure and function, population dynamics, and species responses to environmental change. It provides critical foundations for fisheries science, conservation biology, and environmental monitoring by characterizing species diversity, life histories, habitat requirements, and patterns of endemism, as well as identifying indicators of ecosystem health and anthropogenic impact in marine, brackish, and freshwater systems.

The fish species that knows when you are watching them

Emperor cichlids, large fish native to Lake Tanganyika in Africa, don't like being stared at, especially if someone's gaze is directed at their offspring. Those are the findings of a new study published in the journal Royal ...
