Limanda Limanda
The common dab (''Limanda limanda'') is an edible flatfish of the family Pleuronectidae. It is a demersal fish native to shallow seas around Northern Europe, in particular the North Sea, where it lives on sandy bottoms down to depths of about . It can reach in length and can weigh up to , though most specimens grow no longer than . Taxonomy and nomenclature The etymology of the name ''dab'' is unclear, but the modern English use seems to originate from the Middle English ''dabbe''. It is first recorded in the late 16th century. The common dab was first named ''Pleuronectes limanda'' by Carl Linnaeus in the 1758 10th edition of ''Systema Naturae''. It has also been moved to other genera, including ''Liopsetta'', and is now known as ''Limanda limanda''. Identification The common dab has a similar appearance to both the plaice and the flounder, and similarly has both its eyes normally on the right-hand side of its body. The upper surface is usually pale brown in colour with scat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digestive Gland
The hepatopancreas, digestive gland or midgut gland is an organ of the digestive tract of arthropods and molluscs. It provides the functions which in mammals are provided separately by the liver and pancreas, including the production of digestive enzymes, and absorption of digested food. Arthropods Arthropods, especially detritivores in the Order Isopoda, Suborder Oniscidea (woodlice), have been shown to be able to store heavy metals in their hepatopancreas. This could lead to bioaccumulation through the food chain and implications for food web destruction, if the accumulation gets high enough in polluted areas; for example, high metal concentrations are seen in spiders of the genus ''Dysdera'' which feed on woodlice, including their hepatopancreas, the major metal storage organ of isopods in polluted sites. Molluscs The hepatopancreas is a centre for lipid metabolism and for storage of lipids in gastropods.Böer M., Graeve M. & Kattner G. (2006). "Exceptional long-term starvat ...

Animals Described In 1907
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...

Laurentian Channel
The Laurentian Channel is a deep submarine valley off the coast of eastern Canada in the Gulf of Saint Lawrence. The channel is of glacial origin and is the submerged valley of the historic Saint Lawrence River, running from a sharp escarpment downstream from the confluence of the St. Lawrence with the Saguenay River, past Anticosti Island and through the Gulf of St. Lawrence to the edge of the continental shelf off the island of Newfoundland. Its depth ranges from with sub-tidal shelves on each side of the channel ranging in depths of less than . The channel ranges from a minimum width of to as much as at the Laurentian fan which is located at the edge of the continental shelf. Deep waters with temperatures between enter the Gulf at the continental slope and are slowly advected up the channel by estuariane circulation. Over the 20th century, the bottom waters of the end of the channel (i.e. in the Saint Lawrence estuary) have become hypoxic. Ecological importance The Lau ...

Prince Edward Island
Prince Edward Island (PEI; ) is one of the thirteen Provinces and territories of Canada, provinces and territories of Canada. It is the smallest province in terms of land area and population, but the most densely populated. The island has several nicknames: "Garden of the Gulf", "Birthplace of Confederation" and "Cradle of Confederation". Its capital and largest city is Charlottetown. It is one of the three Maritime provinces and one of the four Atlantic provinces. Part of the traditional lands of the Miꞌkmaq, it was colonized by the French in 1604 as part of the colony of Acadia. The island was ceded to the British at the conclusion of the French and Indian War in 1763 and became part of the colony of Nova Scotia, and in 1769 the island became its own British colony. Prince Edward Island hosted the Charlottetown Conference in 1864 to discuss a Maritime Union, union of the Maritime provinces; however, the conference became the first in a series of meetings which led to Canadi ...

Gaspé Bay
Gaspé Bay () is a bay located on the northeast coast of the Gaspé Peninsula, Quebec, in the Gulf of St. Lawrence. The town of Gaspé, Quebec lies on a part of its southern shore, while most of its northern shore is in the Forillon National Park. The main rivers draining to the bay are the Dartmouth River and the York River (the latter one has its mouth in the city center of Gaspé). Gaspé Bay is where Jacques Cartier took possession of New France (now part of Canada) in the name of François I of France on July 24, 1534 - the beginning of France's overseas expansion. British General James Wolfe raided the Bay in the Gulf of St. Lawrence Campaign (1758), the year before the Siege of Quebec.

Endoparasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hermaphroditic
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species (called trioecy); these three systems are so ...
