The Gulf Killifish

Gulf Killifish is a relatively large killifish of grassy bays, canals and nearby freshwater margins. Small pearly spots add detail to its elongated body.

Range and Identity

The distribution extends around Florida and the northern Gulf toward Cuba. The fish is Fundulus grandis, a particular coastal killifish rather than a generic name for every small baitfish in a marsh. Locality and body features should remain linked.

Vegetated Water

Grassy bays and canals are characteristic habitat, with additional use of neighboring fresh water. A location near the coast can contain several different salinity conditions. Recording the actual salinity and cover is more informative than assuming every canal is entirely freshwater.

Food and Size

Small crustaceans and other invertebrates are recorded foods. The maximum reference is eighteen centimeters total length, with a common length of 10.4 centimeters. Gulf Killifish is not an annual species, so a compulsory seasonal-pool die-off should not be added to its life history.

Keep the Salinity Detail

A vegetated canal or bay can change in salinity. That detail helps explain where Gulf Killifish occurs along the coastal freshwater boundary.
