Sturgeons
Seven species of sturgeon have been reported in North America, and two of them are found in California waters: green sturgeon, Acipenser medirostris, and white sturgeon, Acipenser transmontanus. Both are anadromous and native to the Sacramento-San Joaquin estuary. [eng] |

Sturgeon Family, Acipenseridae
Sturgeons are primitive fishes with rows of bony, armorlike plates on their sides and a skeleton of cartilage rather than bones. Their tail is heterocercal, the backbone extending into the larger, upper lobe of the tail. This structure is similar to the tail of the shark and some other primitive fishes Four barbels hang under the sturgeon's long, flattened snout in front of the mouth. Sturgeon are bottom feeders, their sensory barbels being used to detect food and their protruded, tubelike mouth, to suck in bottom-dwelling plants and animals uncovered as they move along the mud.
