Begg Rock
Begg Rock is an offshore rock pinnacle system in the Begg Rock State Marine Reserve. It is located northwest of ''Vizcaino Point'', the west point of San Nicolas Island, Ventura County, California. It rises from the ocean floor, with its highest pinnacle reaching an elevation of 15 feet (4.6 m) above sea level. A reef extends both the north and south of the island by over 100 yards (91 m) each. A lighted whistle buoy is north of the rock. This rock may be found on NOAA chart 18755. This rock was named by the Coast Survey, after the boat '' John Begg'', which struck a nearby rock in 1824. Begg Rock extends almost vertically down from above the surface. It has several pinnacles, a couple of which are always above water and a couple that are only exposed at low tide. The vertical walls of the rock are covered in filter-feeding organisms such as mussels, green anemones, and pisaster starfish. Below 40 feet (12 meters) are large areas of brightly colored Corynactis anemones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ventura County
Ventura County () is a county in the southern part of the U.S. state of California. As of the 2020 census, the population was 843,843. The largest city is Oxnard, and the county seat is the city of Ventura. Ventura County comprises the Oxnard–Thousand Oaks–Ventura, CA Metropolitan Statistical Area, which is part of the Greater Los Angeles area (Los Angeles-Long Beach, CA Combined Statistical Area). It is also considered the southernmost county along the California Central Coast. Two of the Channel Islands are part of the county: Anacapa Island, which is the most visited island in Channel Islands National Park, and San Nicolas Island. History Pre-colonial period Ventura County was historically inhabited by the Chumash people, who also settled much of Santa Barbara and San Luis Obispo Counties, with their presence dating back 10,000–12,000 years. The Chumash were hunter-gatherers, fishermen, and also traders with the Mojave, Yokuts, and Tongva Indians. The Chumash are ...

Corynactis
''Corynactis'' is a genus of colonial anthozoans similar in appearance to sea anemones and in body format to scleractinian stony corals. These animals are cnidarians in the family Corallimorphidae. Large unidentified polyps of this genus feed on the crown-of-thorns seastar ''Acanthaster planci'' and may help control the crown-of-thorns population. Species Species so far described in this genus include: *''Corynactis annulata'' Verrill, 1867 *''Corynactis australis'' Haddon & Duerden, 1896 *''Corynactis caboverdensis'' den Hartog, Ocaña & Brito, 1993 *''Corynactis californica'' Carlgren, 1936 *''Corynactis caribbeorum'' den Hartog, 1980 *''Corynactis carnea'' Studer, 1879 *''Corynactis chilensis'' Carlgren, 1941 *''Corynactis delawarei'' Widersten, 1976 *''Corynactis denhartogi'' Ocaña, 2003 *''Corynactis denticulosa'' Le Sueur, 1817 *''Corynactis globulifera'' Hemprich & Ehrenberg in Ehrenberg, 1834 *''Corynactis parvula'' Duchassaing & Michelotti, 1860 *''Corynactis sanmatiens ...

Islands Of Southern California
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marine Reserve
A marine reserve is a type of marine protected area (MPA). An MPA is a section of the ocean where a government has placed limits on human activity. A marine reserve is a marine protected area in which removing or destroying natural or cultural resources is prohibited, marine reserves may also be "no-take MPAs,” which strictly forbid all extractive activities, such as fishing and kelp harvesting.. As of 2007 less than 1% of the world's oceans had been set aside in marine reserves. Benefits include increases in the diversity, density, biomass, body size and reproductive potential of fishery and other species within their boundaries. As of 2010, scientists had studied more than 150 marine reserves in at least 61 countries and monitored biological changes inside the reserves. The number of species in each study ranged from 1 to 250 and the reserves ranged in size from 0.006 to 800 square kilometers (0.002 to 310 square miles). In 2014, the World Parks Association adopted a target ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scallop
Scallop () is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters. Scallops are a cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. The majority of species, however, live recumbent on sandy substrates, and when they sense the presence of a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metridium
Members of the genus ''Metridium'', also known as plumose anemones, are sea anemones found mostly in the cooler waters of the northern Pacific and Atlantic oceans. They are characterized by their numerous threadlike tentacles extending from atop a smooth cylindrical column, and can vary from a few centimeters in height up to one meter or more. In larger specimens, the oral disk becomes densely curved and frilly. Species The following species are recognised in the World Register of Marine Species (WoRMS): *''Metridium canum'' Frederick George Albert Stuckey, Stuckey, 1914 *''Metridium dianthus'' Ellis, 1768 *''Metridium exile'' Hand, 1956 *''Metridium farcimen'' (Wilhelm Gottlieb Tilesius von Tilenau, Tilesius, 1809) – giant plumose anemone or white-plumed anemone *''Metridium huanghaiensis'' Pei, 1998 *''Metridium senile'' (Linnaeus, 1761) – frilled anemone *''Metridium sinensis'' Pei, 1998 References External linksVideos of the Metridium Fields in Monterey, CA]Photos [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pisaster Ochraceus
''Pisaster ochraceus'', generally known as the purple sea star, ochre sea star, or ochre starfish, is a common seastar found among the waters of the Pacific Ocean. Identified as a keystone species, ''P. ochraceus'' is considered an important indicator for the health of the intertidal zone. Description This sea star has five stout rays that range in length from 10 to 25 centimeters (4 to 10 in). The rays are arranged around an ill-defined central disk. While most individuals are purple, they can be orange, orange-ochre, yellow, reddish, or brown. The aboral surface contains many small spines (ossicles) that are arranged in a netlike or pentagonal pattern on the central disk. The ossicles are no higher than 2 mm.Kozloff, E. N. (1996).
