Pacific Sea Nettle

The Pacific Sea nettle (Chrysaora fuscescens, also referred to as the West Coast sea nettle is a sea nettle. Sea nettles are a common variation of true jellyfish (scyphozoan) that are found in the Pacific Ocean. The Pacific Sea nettle is mostly found near the cost of California to Alaska (and maybe to Japan also), although the species was originally reported far offshore in the North Pacific. Because of human influences near the coastal regions some believe that the Pacific Sea nettle population is increasing, however, there is little to no data about the species to compare current and past populations. This assumed growth of the species population is said to have a negative influence on the larval population.

The diameter of the bell (body) can measure more than 3 feet, although most of the Pacific Sea nettle measure less than 1 foot across. The spiraling oral arms that are long and complicated along with the 24 tentacles may trail as far as 12 to 15 feet behind the bell.

In the late summer the Pacific Sea nettle may be present in large numbers in the coastal waters. The Pacific Sea nettle is colorful and quite easy to maintain indoors, therefore this species is on exhibit at the Monterey Bay Aquarium in California and is also displayed at numerous public aquariums in America and elsewhere.
