CATANDROMOUS Meaning and
Definition
-
Catandromous is a term used in biology to describe a rare phenomenon observed in certain fish species, particularly in the context of their migration and reproductive behavior. It refers to a specific form of dichromatism, wherein individuals within the same species exhibit different sexual characteristics depending on their location within a population. This peculiarity is primarily associated with anadromous fish species - ones that migrate from the ocean to freshwater environments for spawning.
In catadromous species, males and females possess distinct physical traits in different stages of their life cycle. Typically, males have bright and vibrant coloration during the breeding season, showcasing various patterns and pigments to attract females for mating. Conversely, females tend to have more subdued or camouflaged coloration that aids in their protection and survival during the spawning period.
This unique characteristic of catandromy is thought to be an advantageous adaptation for reproductive success, as it allows for enhanced sexual selection and reduced competition between males vying for mates. It also aids in differentiating individuals within a population, which can be crucial for species recognition and species-specific behavior during breeding events.
In summary, catandromous refers to the dichromatism observed in certain fish species, where males and females display different sexual characteristics based on their habitat or life stages. This phenomenon plays a significant role in their reproductive behavior and mate selection, providing evolutionary advantages for successful breeding.

Etymology of CATANDROMOUS
The word "catandromous" is derived from the Greek words "kata" meaning "downwards" or "against" and "andros" meaning "man" or "male". The term was coined in the early 20th century to describe certain types of fish that exhibit unusual migratory behavior, where they migrate downstream from freshwater to saltwater environments for breeding purposes. The word refers to the masculinization of the fish during this process, as they transition from the freshwater environment to the marine environment.
