Bermuda Killifish (Fundulus bermudae) & Lover's Lake Killifish (Fundulus relictus)

 

Female killifish are olive coloured and sometimes have dark vertical bars running down their bodies.  Males are smaller than females, more brightly coloured, and have a dark eyespot on their dorsal fin during the breeding season.  Most killifish average 6 cm in length (about the size of your first finger), although some have been found nearly 13 cm.

Killifish are euryhaline, meaning they can live in either fresh or saltwater, and are only found in a limited number of ponds scattered across the Bermuda. They are omnivorous, feeding on small invertebrates, such as shrimp and insects, as well as plant material and pond sediment. Female killifish lay their eggs one at a time over a period of several days in the summer. The fry (baby killifish) hatch after a few weeks and can grow up to live for many years.

There is concern that some of our killifish may be disappearing. Loss of suitable habitat, predation, competition pressures and pollution are all threats to Bermuda’s killifish.
