For Gallery-Slideshow and Resources for Identifying Fishes


* Kelp Bass (aka Calico Bass) “Rather than mating over brief periods each year, they may spawn any time from April to November. Apparently during this time they form large groups a little further from the coast. The fertilized eggs drift in the plankton for a few days before hatching into larvae. The larvae remain as temporary plankton (“meroplankton”) for about a month before they settle out over appropriate habitat. Although some scientific reports suggest that members of this species stick around their home reef or kelp forest, Dr. Love has observed large schools of them miles at sea. Some believe these groups move into suitable habitats like rocky reefs for short periods. Those that find habitats with plenty of food may exhibit “site fidelity” and stick around.”

Best Natural History Sites (i.e. not just identification but habitat, place in ecosystem, etc) • focus on Marine Life and Marine Birds

  • Cornell All About Birds: For Identification: Photos, Videos, Recordings + Life History: Habitat, Food, Nesting, Behavior, Conservation: e.g. Snowy Plover; e.g. Brown Pelican
