Burntcoat Head, Nova Scotia
Burntcoat Head (improperly known as Burncoat) is an unincorporated rural Canadian community in Hants County, Nova Scotia. The area is known for having the largest tidal range (the greatest difference in height between high tide and low tide) of any location in the world. Etymology The origin of the name "Burntcoat" or "Burncoat", as the community is sometimes named, is unknown. The derivation of the spelling of the name is also unclear. Today the village on the ''west'' side of the Noel Bay is named Burntcoat, however, the Acadians named the village on the ''east'' side of the Noel Bay "Pointe Brull" (i.e., Burnt Point or Burnt Coast). Perhaps the Protestant settlers who came after the exodus of the Acadians from the community confused the names for the east and west side of the Noel Bay and thought the west side of the bay was "Pointe Brull". The Acadian name for ''west'' side of Noel Bay (i.e., present day Burntcoat) was "Pointe Cloche", indicating a chapel was likely locate ...

Naticidae
Naticidae, common name moon snails or necklace shells, is a family (biology), family of medium to large-sized predatory sea snails, marine (ocean), marine gastropod molluscs in the clade Littorinimorpha. The shells of the species in this family are mostly globular in shape. Naticidae is the only family in the superfamily Naticoidea. It has been estimated that worldwide there are about 260–270 Holocene, recent species of naticid snails. This group is assumed to have originated in the late Triassic or in the early Jurassic. Members of this family can be recognized by the shape of their shells, distinct appearance, or by their predatory behavior. Distribution Naticids are widely distributed and occur worldwide. The greatest Biodiversity, diversity of both species and genera is found in tropical regions. Even so, naticid snails are also plentiful in temperate, Arctic and Antarctic waters. Habitat Moon snails live on sandy substrate (biology), substrates, at a great variety of dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Mackerel
The Atlantic mackerel (''Scomber scombrus''), also known as Boston mackerel, Norwegian mackerel, Scottish mackerel or just mackerel, is a species of mackerel found in the temperate waters of the Mediterranean Sea, the Black Sea, and the northern Atlantic Ocean, where it is extremely common and occurs in huge shoals in the epipelagic zone down to about . It spends the warmer months close to shore and near the ocean surface, appearing along the coast in spring and departing with the arrival of colder weather in the fall and winter months. During the fall and winter, it migrates out into deeper and more southern water, seeking warmer temperatures. The Atlantic mackerel's body is elongate, steel-blue marked with wavy black lines dorsally and silvery-white ventrally, its snout long and pointed. It possesses two spiny dorsal fins, which are spaced far apart, two pectoral fins, and small caudal and anal fins, also spaced far apart. 4-6 dorsal finlets and 5 anal finlets are typical among ...

Microgadus Tomcod
''Microgadus tomcod'', also commonly known as frostfish, Atlantic tomcod or winter cod, is a type of cod found in North American coastal waters from the Gulf of St. Lawrence, St. Lawrence River and northern Newfoundland, south to Virginia. The fishing season of the tomcod varies by location—one known example is the Sainte-Anne River in Quebec, where its season is from late-December to mid-February. A bimonitoring program tracked hormone levels of Atlantic tomcod caught near Miramichi and Kouchibouguac in 1993 and 1994, demonstrating that the preparatory period for spawning began in September with maximal steroid levels in November, and spawning took place from late December to January. The town of Sainte-Anne-de-la-Pérade is notable for its fishing village built on the frozen waters of the Ste-Anne, playing host to the scores of fishermen visiting the town to fish for the species. After General Electric dumped polychlorinated biphenyls (PCBs) in the Hudson River from 1947 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cancer Irroratus
''Cancer irroratus'' ( common name the ''Atlantic rock crab'' or ''peekytoe crab'') is a crab in the genus ''Cancer''. It is found from Iceland to South Carolina at depths up to , and reaches across the carapace. Distribution This crab species occurs on the eastern coast of North America, from Iceland to South Carolina. Rock crabs live over a large depth range, from well above the low tide line to as deep as . Description ''Cancer irroratus'' has nine marginal teeth on the front edge of the carapace beside each eye, and reaches a carapace width of . These crabs are similar in color to, and overlap in size with, the Jonah crab, ''Cancer borealis''. The two species can indeed be distinguished by the purplish-brown spots on the carapace of ''C. irroratus'' (contrasting with the yellow spots of ''C. borealis''), and by the smooth edges to the teeth on the edge of the carapace (denticulate in ''C. borealis''). Fisheries The rock crab has recently become a popular culinary item. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ovalipes Ocellatus
''Ovalipes ocellatus'', known as the lady crab, is a species of crab from eastern North America. Other names for it include the leopard crab or Atlantic leopard crab due to the leopard-like rosette patterns on its shell, the calico crab (not to be confused with ''Hepatus epheliticus''), or ocellated crab. It has a shell long and only slightly wider, which is covered in clusters of purple spots. It occurs from Canada to Georgia, and lives mainly on molluscs, such as the Atlantic surf clam. Taxonomy ''O. ocellatus'' was first described by Johann Friedrich Wilhelm Herbst in 1799, as ''Cancer ocellatus''. In 1898, Mary Jane Rathbun moved the species to her new genus ''Ovalipes''. Description The carapace of ''O. ocellatus'' is slightly wider than long, at wide, and long. This distinguishes it from other crabs in the family Portunidae, which often have elongated lateral spines. The carapace is yellow-grey or light purplish, with "leopardlike clusters of purple dots", and 3–5 spi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermit Crab
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless. The strong association between hermit crabs and their shelters has significantly influenced their biology. Almost 800 species carry mobile shelters (most often calcified snail shells); this protective mobility contributes to the diversity and multitude of crustaceans found in almost all marine environments. In most species, development involves metamorphosis from symmetric, free-swimming larvae to morphologically asymmetric, benthic-dwelling, shell-seeking crabs. Such physiological and behavioral extremes facilitate a transition to a sheltered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carcinus Maenas
''Carcinus maenas'' is a common littoral crab. It is known by different names around the world. In the British Isles, it is generally referred to as the shore crab, or green shore crab. In North America and South Africa, it bears the name european green crab. ''C. maenas'' is a widespread invasive species, listed among the 100 "world's worst alien invasive species". It is native to the north-east Atlantic Ocean and Baltic Sea, but has colonised similar habitats in Australia, South Africa, South America and both Atlantic and Pacific coasts of North America. It grows to a carapace width of , and feeds on a variety of mollusks, worms, and small crustaceans, potentially affecting a number of fisheries. Its successful dispersal has occurred by a variety of mechanisms, such as on ships' hulls, sea planes, packing materials, and bivalves moved for aquaculture.

Alcyonium Digitatum
''Alcyonium digitatum'' or dead man's fingers is a species of soft coral in the family Alcyoniidae. It is found around the coasts of the northern Atlantic Ocean and other temperate waters such as the South Pacific. Description Dead man's fingers is a colonial coral forming clumps of yellow, white or cream-coloured fleshy masses of finger-like lobes. The surface layer include many sclerites which form a crust. The individual polyps are white and translucent, and project from the leathery surface when feeding, giving the colony a furry appearance. Distribution and habitat Dead man's fingers is found along the Atlantic coasts of north west Europe from Portugal to Norway, most recently being discovered in the unchartered waters of Jammerbugt bay off the north-west coast of Denmark by a 2020 seafloor mapping project led by explorer Klaus Thymann. The species also occurs in parts of Canada, northeastern coast of the United States, the Gulf of Maine and the Bay of Fundy and the norther ...
