Fundulus heteroclitus

A killifish species in topminnows genus Fundulus which is native to Atlantic saltwater marshes and tidal creeks. It is commonly known as mummichog or Atlantic killifish. Fundulus heteroclitus is a model organism for toxicogenomics and related fields because of its high resistance to environmental toxins; short intervals between spawning (10 days); large number of eggs (up to 300 each spawning) and relatively long lifespan (4 years).
