Theodore Dru Alison Cockerell
Theodore Dru Alison Cockerell (1866–1948) was an American zoologist, born at Norwood, England, and brother of Sydney Cockerell. He was educated at the Middlesex Hospital Medical School, and then studied botany in the field in Colorado in 1887–90. Subsequently, he became a taxonomist and published numerous papers on the Hymenoptera, Hemiptera, Mollusca and plants, as well as publications on paleontology and evolution. Personal life Cockerell was born in Norwood, Greater London and died in San Diego, California. He married Annie Sarah Fenn in 1891 (she died in 1893) and Wilmatte Porter in 1900. In 1901, he named the ultramarine blue chromodorid ''Mexichromis porterae'' (now '' Felimare porterae'') in her honor. After their marriage in 1900, they frequently went on collecting expeditions together and assembled a large private library of natural history films, which they showed to schoolchildren and public audiences to promote the cause of environmental conservation.

Elkhorn Slough
Elkhorn Slough is a tidal slough and estuary on Monterey Bay in Monterey County, California. It is California's second largest estuary and the United States' first estuarine sanctuary. The community of Moss Landing and the Moss Landing Power Plant are located at the mouth of the slough on the bay. Elkhorn Slough harbors the largest tract of tidal salt marsh in California outside the San Francisco Bay and provides much-needed habitat for hundreds of species of plants and animals, including more than 340 species of birds. It has been designated as a protected Ramsar site since 2018. History The name of the slough derives from the native tule elk ''Cervus canadensis nannodes'', now extirpated from the region. Elkhorn Slough occupies the western reaches of Elkhorn Valley, a relic river valley eroded by drainage pouring out of the Santa Clara Valley and/or Great Valley of California (before the Golden Gate opened) into Monterey Bay during the early Pleistocene. In the mid-1850s A.D. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinophore
A rhinophore is one of a pair of chemosensory club-shaped, rod-shaped or ear-like structures which are the most prominent part of the external head anatomy in sea slugs, marine gastropod opisthobranch mollusks such as the nudibranchs, sea hares ( Aplysiomorpha), and sap-sucking sea slugs ( Sacoglossa). Etymology The name relates to the rhinophore's function as an organ of "smell". ''Rhino-'' means nose from Ancient Greek ῥίς ''rhis'' and from its genitive ῥινός ''rhinos''. "Phore" means "to bear" from New Latin ''-phorus'' and from Greek -phoros (φορος) "bearing", a derivative of ''phérein'' (φέρειν). Function Rhinophores are scent or taste receptors, also known as chemosensory organs situated on the dorsal surface of the head. They are primarily used for distance chemoreception and rheoreception (response to water current). The "scents" detected by rhinophores are chemicals dissolved in the sea water. The fine structure and hairs of the rh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flabellina Cooperi - Adult And Juvenile - From Santa Cruz, California
''Flabellina'' is a genus of sea slugs, specifically Aeolidioidea, aeolid nudibranchs. These animals are marine (ocean), marine gastropod molluscs in the family (biology), family Flabellinidae. Taxonomic history The genus ''Flabellina'' was established by John Edward Gray in 1833 with the type species ''Flabellina affinis'' and characterised by the cerata being arranged on peduncles and the rhinophores being annulate. Many species were added by subsequent authors. In 1981 the genus ''Coryphella'' was merged under the older name ''Flabellina'' as despite a large range of morphological characters in the 64 species of Flabellinidae and Coryphellidae known at that time, no clear distinction could be found to separate the species into the two genera. In 2017 an integrative study of the 71 species then considered to be included in ''Flabellina'' redistributed the species into seven families and 26 genera. Species Species currently included in this genus are: * ''Flabellina affinis'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baja California
Baja California (; 'Lower California'), officially the Free and Sovereign State of Baja California ( es, Estado Libre y Soberano de Baja California), is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California (). It has an area of (3.57% of the land mass of Mexico) and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean; on the east by Sonora, the U.S. state of Arizona, and the Gulf of California; on the north by the U.S. state of California; and on the south by Baja California Sur. The state has an estimated population of 3,769,020 as of 2020, significantly higher than the sparsely populated Baja California Sur to the south, and similar to San Diego County, California, to its north.

San Quintín, Baja California
San Quintín is a city in San Quintín Municipality, Baja California, located on the Pacific Coast of Mexico. The city had a population of 4777 in 2011. San Quintín is an important agricultural center for Baja California. The city is also an emerging tourist destination, known for its sand dunes and beaches. History In the 1880s, a British land company with plans for a wheat empire purchased much of the San Quintín area from the US–based International Land Company (ILC); at the time, ILC owned most of northern Baja. In response to promises of agricultural wealth, around a hundred English colonists purchased subdivided land tracts from the parent company, planted wheat, and constructed a gristmill. For flour transportation, the English built a pier on inner Bahiá San Quintín and began constructing a railway to link up with the Southern Pacific tracks to the north in California. Thirty kilometers of track were laid, including a rail causeway from the west bank of inner Bahi� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California Current
The California Current is a cold water Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Sur. It is considered an Eastern boundary current due to the influence of the North American coastline on its course. It is also one of five major coastal currents affiliated with strong upwelling zones, the others being the Humboldt Current, the Canary Current, the Benguela Current, and the Somali Current. The California Current is part of the North Pacific Gyre, a large swirling current that occupies the northern basin of the Pacific. Physical properties The movement of Alaskan and northern ocean currents southward down the west coast results in much cooler ocean temperatures than at comparable latitudes on the east coast of the United States, where ocean currents come from the Caribbean and tropical Atlantic. The cooler ocean current along the west coast also makes sum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
