S. F. Light
Sol Felty Light (May 5, 1886 – June 21, 1947) was an American zoologist, entomologist, and professor at the University of California, Berkeley, known for his research on caste development in termites in the first half of his career, and for teaching marine zoology courses in the second half. From 1913 to 1947, he published approximately 70 papers, most on the subject of entomology. His class syllabus on zooology was originally designed for students at Berkeley, but in 1941 it was published as an invertebrate zoology textbook and field guide that had larger appeal, as it was considered the first complete compendium of marine invertebrates in the north central California coastal region ever published. After Light's death, the book was edited, revised, and expanded by Ralph I. Smith and other contributors, becoming known as ''Light's Manual''. After Smith himself died, the book was renamed ''The Light and Smith Manual'' in his honor. Light's students went on to distinguished care ...

Flagellate
A flagellate is a cell or organism with one or more whip-like appendages called flagella. The word ''flagellate'' also describes a particular construction (or level of organization) characteristic of many prokaryotes and eukaryotes and their means of motion. The term presently does not imply any specific relationship or classification of the organisms that possess flagella. However, the term "flagellate" is included in other terms (such as "dinoflagellate" and "choanoflagellata") which are more formally characterized. Form and behavior Flagella in eukaryotes are supported by microtubules in a characteristic arrangement, with nine fused pairs surrounding two central singlets. These arise from a basal body. In some flagellates, flagella direct food into a cytostome or mouth, where food is ingested. Flagella often support hairs, called mastigonemes, or contain rods. Their ultrastructure plays an important role in classifying eukaryotes. Among protoctists and microscopic anima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Sarton
George Alfred Leon Sarton (; 31 August 1884 – 22 March 1956) was a Belgian-born American chemist and historian. He is considered the founder of the discipline of the history of science as an independent field of study. His most influential works were the ''Introduction to the History of Science'', which consists of three volumes and 4,296 pages and the journal ''Isis''. Sarton ultimately aimed to achieve an integrated philosophy of science that provided a connection between the sciences and the humanities, which he referred to as "the new humanism". Sarton's life and work George Alfred Leon Sarton was born to Léonie Van Halmé and Alfred Sarton on August 31, 1884 in Ghent, East Flanders, Belgium. However, within a year of his birth, Sarton's mother died. He attended school first in his hometown before later attending school for a period of four years in the town of Chimay. Sarton enrolled at the University of Ghent in 1902 to study philosophy, but found that the subject did not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lancelet
The lancelets ( or ), also known as amphioxi (singular: amphioxus ), consist of some 30 to 35 species of "fish-like" benthic filter feeding chordates in the order Amphioxiformes. They are the modern representatives of the subphylum Cephalochordata. Lancelets closely resemble 530-million-year-old ''Pikaia'', fossils of which are known from the Burgess Shale. Zoologists are interested in them because they provide evolutionary insight into the origins of vertebrates. Lancelets contain many organs and organ systems that are closely related to those of modern fish, but in more primitive form. Therefore, they provide a number of examples of possible evolutionary exaptation. For example, the gill-slits of lancelets are used for feeding only, and not for respiration. The circulatory system carries food throughout their body, but does not have red blood cells or hemoglobin for transporting oxygen. Lancelet genomes hold clues about the early evolution of vertebrates: by comparing genes from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scyphozoa
The Scyphozoa are an exclusively marine class of the phylum Cnidaria, referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word ''skyphos'' (), denoting a kind of drinking cup and alluding to the cup shape of the organism. Scyphozoans have existed from the earliest Cambrian to the present. Biology Most species of Scyphozoa have two life-history phases, including the planktonic medusa or polyp form, which is most evident in the warm summer months, and an inconspicuous, but longer-lived, bottom-dwelling polyp, which seasonally gives rise to new medusae. Most of the large, often colorful, and conspicuous jellyfish found in coastal waters throughout the world are Scyphozoa. They typically range from in diameter, but the largest species, ''Cyanea capillata'' can reach across. Scyphomedusae are found throughout the world's oceans, from the surface to great depths; no Scyphozoa occur in freshwater (or on land). As medusae, they eat a ...

Octocorallia
Octocorallia (also known as Alcyonaria) is a class of Anthozoa comprising around 3,000 species of water-based organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians (sea fans and sea whips) within three orders: Alcyonacea, Helioporacea, and Pennatulacea. These organisms have an internal skeleton secreted by mesoglea and polyps with eight tentacles and eight mesentaries. As with all Cnidarians these organisms have a complex life cycle including a motile phase when they are considered plankton and later characteristic sessile phase. Octocorals have existed at least since the Ordovician period, as shown by Maurits Lindström's findings in the 1970s, however recent work has shown a possible Cambrian origin. Biology Octocorals resemble the stony corals in general appearance and in the size of their polyps, but lack the distinctive stony skeleton. Also unlike the stony corals, each polyp has only eight tentacle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coelenterata
Coelenterata is a term encompassing the animal phyla Cnidaria (coral animals, true jellies, sea anemones, sea pens, and their relatives) and Ctenophora (comb jellies). The name comes , referring to the hollow body cavity common to these two phyla. They have very simple tissue organization, with only two layers of cells (ectoderm and endoderm), and radial symmetry. Some examples are corals, which are typically colonial, and hydrae, jellyfish, and sea anemones, which are solitary. Coelenterata lack a specialized circulatory system relying instead on diffusion across the tissue layers. Characteristics All coelenterates are aquatic, mostly marine, animals. The body form is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the , surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey. These tentacles are surrounded by a spacious cavity called the gastrovascular cavity, or coelen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alvin Seale
Alvin Seale (July 8, 1871 – July 28, 1958) was a naturalist known for his aquarium design and as an ichthyologist. Early life Alvin Seale was born on July 8, 1871, in Fairmount, Indiana, to a family of Quakers. In 1892, he attended Stanford University, and was tutored by David Starr Jordan. Education In 1896, the year that Seale would have graduated from Stanford in zoology, he was picked by Professor Jordan, along with fellow student Norman B. Scofield, to go to Point Barrow in Alaska. His mission was to look for salmon in the Mackenzie River. Travels Before returning to Stanford Seale collected sea birds along the Alaskan coast on behalf of the British Museum. He also went with his roommate to the Klondike to join the gold rush there. According to Seale, his companion “struck it rich.” Seale, however, was too busy exploring the native wildlife to waste his time searching for gold. In his unpublished diary Seale writes that he spent “an exciting year." Polynesian c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
