Three Reproductive Phenotypes in the Plainfin Midshipman Fish
With more than 24,000 species, fish are the most diverse vertebrate group. Teleost (bony) fish in particular exhibit a dazzling variety of social behaviors, including some forms of physiological and behavioral plasticity that have not been achieved in other taxa (e.g, sex change). Many SBN members therefore focus on fish as a means of understanding how neuroendocrine processes can mediate phenotypic plasticity during development and/or during adulthood.
