Joubin's Squid
''Joubiniteuthis portieri'', also known as Joubin's squid from the monotypic family Joubiniteuthidae and genus ''Joubiniteuthis''. It is a rare, small squid which occurs in the mesopelagic to bathypelagic zones and which has a worldwide distribution in tropical and subtropical regions. It is a distinctive squid having long arms I-III which have numerous small suckers in six rows. Its biology is little known and it is thought that it stays in the depths of the ocean with its arms outstretched waiting for small animals to ensnare after they have accidentally swum into the arms. This species is named after Louis Joubin, a French zoologist. It is known to reach a mantle A mantle is a piece of clothing, a type of cloak. Several other meanings are derived from that. Mantle may refer to: *Mantle (clothing), a cloak-like garment worn mainly by women as fashionable outerwear **Mantle (vesture), an Eastern Orthodox ve ... length of 9 cm.

Prince Albert I Of Monaco
Albert I (Albert Honoré Charles Grimaldi; 13 November 1848 – 26 June 1922) was Prince of Monaco from 10 September 1889 until his death. He devoted much of his life to oceanography, exploration and science. Alongside his expeditions, Albert I made reforms on political, economic and social levels, bestowing a constitution on the principality in 1911. Early life Born on 13 November 1848 in Paris, France, the son of Prince Charles III (1818–1889), and Countess Antoinette de Mérode-Westerloo (1828–1864), a Belgian noblewoman, maternal aunt of Donna Maria Vittoria dal Pozzo, Princess della Cisterna, Duchess consort of Aosta and Queen consort of Spain.

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish ( Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were '' hunters and gatherers'' who had learned how to obtain the most ...

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this ''large proportion'' is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts ...

Chaetognatha
The Chaetognatha or chaetognaths (meaning ''bristle-jaws'') are a phylum of predatory marine worms that are a major component of plankton worldwide. Commonly known as arrow worms, about 20% of the known Chaetognatha species are benthic, and can attach to algae and rocks. They are found in all marine waters, from surface tropical waters and shallow tide pools to the deep sea and polar regions. Most chaetognaths are transparent and are torpedo shaped, but some deep-sea species are orange. They range in size from . There are more than 120 modern species assigned to over 20 genera. Despite the limited diversity of species, the number of individuals is large. Arrow worms are usually considered a type of protostome that do not belong to either Ecdysozoa or Lophotrochozoa. Anatomy Chaetognaths are transparent or translucent dart-shaped animals covered by a cuticle. The body is divided into a distinct head, trunk, and tail. There are between four and fourteen hooked, grasping spin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Louis Germain
Alfred Louis Pierre Germain (8 January 1878 – 18 October 1942) was a French malacologist born in Niort, department Deux-Sèvres. He studied in Angers and Paris, obtaining his doctorate of sciences in 1907. Later he worked under Louis Joubin in the laboratory of mollusks, worms and zoophytes at the Muséum national d'histoire naturelle in Paris. From 1936 to 1942 he was director of the museum. Recently (2010), a new genus of freshwater mussels from Madagascar called ''Germainaia'' was introduced into science. Written works * ''Étude sur les mollusques terrestres et fluviatiles vivants des environs d'Angers et du département de Maine-et-Loire'', Bulletin of the Society of Natural Sciences of Western France, 1903 – Study of terrestrial and fluviatile mollusks living in the vicinity of Angers and the department of Maine-et-Loire. * ''Les mollusques terrestres & fluviatiles de l'Afrique centrale française'', 1907 - Terrestrial and fluviatile mollusks of French central Af ...

Natural Science
Natural science is one of the branches of science concerned with the description, understanding and prediction of Nature, natural Phenomenon, phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances. Natural science can be divided into two main branches: list of life sciences, life science and Outline of physical science, physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields). As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements which can be explained as clear statements of the "laws of science, laws of nature".

North Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Nemertean
Nemertea is a phylum of animals also known as ribbon worms or proboscis worms, consisting of 1300 known species. Most ribbon worms are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies. Many have patterns of yellow, orange, red and green coloration. The foregut, stomach and intestine run a little below the midline of the body, the anus is at the tip of the tail, and the mouth is under the front. A little above the gut is the rhynchocoel, a cavity which mostly runs above the midline and ends a little short of the rear of the body. All species have a proboscis which lies in the rhynchocoel when inactive but everts to emerge just above the mouth to capture the animal's prey with venom. A highly extensible muscle in the back of the rhynchocoel pulls the proboscis in when an attack ends. A few species with stubby bodies filter feed and have suckers at the front and back ends, with which they attach to a host. The brain is a ring ...
