The plainfin midshipman

Also referred to as our local “toad fish,” the plainfin midshipman (Porichthys notatus) are visiting the slough for breeding and juvenile growth. Adults usually live in depths of around 400m most of the year, but venture into shallow intertidal locations during spring and early summer for breeding. Males can produce a “hum” to attract females to their nesting site. These fish are to blame from past stories of “generator-like” noise complaints in Sausalito, CA.

These fish have hundreds of photophores along their body which are used to produce light for attracting prey.

Kenton Parker and Cortland Jordan have been following up on development of these little guys from beginning stages of egg masses to early juvenile development.

  1. Thanks for the great information on this fish. I got a shot of a cormorant that had just caught one last month. I’d love to share, but new to this blog so will try to figure it out.
