Where do mummichogs live?

Also known as the mud minnow, the mummichog is a minnow-like killifish found along muddy marshes, tidal creeks and the sheltered shores of the Chesapeake Bay.

Where do mummichogs go in winter?

During cold winter months in the northern parts of their range, mummichogs move to upstream tidal pools, where they burrow into the mud at depths up to 20 cm (7.9 in) to overwinter. They can also bury themselves in mud if they are caught in a drying tidal pool between spring tides.
