2.3. Freshwater teleosts
In contrast with their marine and diadromous counterparts, freshwater
teleosts generally undergo more phenotypically subtle metamorphoses.
Few larva-specific adaptations are found in freshwater teleosts, reflecting
the fact that freshwater fish do not generally have an explicitly dispersive larval
stage. Nonetheless, freshwater teleosts undergo numerous morphological and
physiological changes during larval metamorphosis, modifications that have
been described most extensively in the developmental genetic model species
zebrafish
Danio rerio
