Pacific Spiny Dogfish
The Pacific spiny dogfish (''Squalus suckleyi'') is a common species of the Squalidae (dogfish) family of sharks and are among the most abundant species of sharks in the world. This species is closely related to the ''Spiny dogfish'' and for many years they were treated as a single species. Recent research, using Meristics, meristic, Morphometrics, morphological and Molecular genetics, molecular data led to the resurrection of the Pacific spiny dogfish as a separate species. The American Fisheries Society recommends the common name "Pacific spiny dogfish" for ''Squalus suckleyi'' over alternatives such as "spotted spiny dogfish" and "North Pacific spiny dogfish" and "spiny dogfish" for ''Squalus acanthias''. The maximum length of a Pacific dogfish can be , and they can live up to 100 years. ''Squalus suckleyi'' has a slower growth rate, larger maximum size, and later maturity compared to ''Squalus acanthias'' species. The slower growth rate and time of maturity could be related to ...

Spiny Dogfish
The spiny dogfish (''Squalus acanthias''), spurdog, mud shark, or piked dogfish is one of the best known species of the Squalidae (dogfish) family of sharks, which is part of the Squaliformes order. While these common names may apply to several species, ''Squalus acanthias'' is distinguished by two spines (one anterior to each dorsal fin) and no anal fin. It lives in shallow waters and further offshore in most parts of the world, especially in temperate waters. Those in the northern Pacific Ocean were reevaluated in 2010 and found to constitute a separate species, now called the Pacific spiny dogfish (''Squalus suckleyi''). Description and behaviour The spiny dogfish has dorsal fins, no anal fin, and white spots along its back. The caudal fin has asymmetrical lobes, forming a heterocercal tail. The species name ''acanthias'' refers to the shark's two spines. These are used defensively. If captured, the shark can arch its back to pierce its captor with spines near the dorsal ...

Portuguese Dogfish
The Portuguese dogfish (''Centroscymnus coelolepis'') or Portuguese shark, is a species of sleeper shark of the family Somniosidae. This globally distributed species has been reported down to a depth of , making it the deepest-living shark known. It inhabits lower continental slopes and abyssal plains, usually staying near the bottom. Stocky and dark brown in color, the Portuguese dogfish can be distinguished from similar-looking species (such as the kitefin shark, ''Dalatias licha'') by the small spines in front of its dorsal fins. Its dermal denticles are also unusual, resembling the scales of a bony fish. This species typically reaches in length; sharks in the Mediterranean Sea are much smaller and have distinct depth and food preferences. Relatively common, the Portuguese dogfish is an active hunter capable of tackling fast, large prey. It feeds mainly on cephalopods and fishes, though it also consumes invertebrates and cetacean carrion. This shark has acute vision optimized ...

Squalidae
Squalidae, more commonly known as dogfish, dog sharks, or spiny dogfish, are one of several families of sharks categorized under Squaliformes, making it the second largest order of sharks, numbering 119 species across 7 families. Having earned their name after a group of fishermen reportedly observed the species chasing down smaller fish in dog-like packs, dogfish have slender, streamlined bodies, usually more compact in comparison to other species, and a pointed snout. Dogfish likewise have two dorsal fins, each with smooth spines, but no anal fin, and their skin is generally rough to the touch. As the species reaches adulthood, males usually measure a maximum of , while females typically measure long. The species therefore exhibits female-dominant sexual dimorphism. Dogfish sharks have slate-grey or grey-brown skin with white dots that becomes paler (almost white) around the belly region. These sharks are characterized by teeth in upper and lower jaws similar in size; a cauda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sleeper Sharks
The Somniosidae are a family of sharks in the order Squaliformes, commonly known as sleeper sharks. The common name "''sleeper shark''" comes from their slow swimming, low activity level, and perceived non-aggressive nature. Distribution and habitat The Somniosidae can be found in: *Arctic to subantarctic waters *Shelves in cold waters *Continental and slopes *Temperate and tropical waters Diet Beaks recovered from the stomachs of sleeper sharks suggest they feed on colossal squid.Cherel, Y. & G.

Scyliorhinidae
Scyliorhinidae is a Family (biology), family of sharks, one of a few families whose members share the common name catsharks, belonging to the Order (biology), order Carcharhiniformes, the ground sharks. Although they are generally known as catsharks, some species can also be called dogfish due to previous naming. However, a dogfish may generally be distinguished from a catshark as catsharks lay eggs while dogfish have live young. Like most bottom feeders, catsharks feed on benthic invertebrates and smaller fish. They are not harmful to humans. The family is paraphyletic, containing several distinct lineages that do not form a monophyletic group. Genera Scyliorhinidae includes the following genera: * ''Cephaloscyllium'' Theodore Gill, T. N. Gill, 1862 * ''Poroderma'' Andrew Smith (zoologist), A. Smith, 1838 * ''Scyliorhinus'' Henri Marie Ducrotay de Blainville, Blainville, 1816 Anatomy and appearance Scyliorhinidae catsharks may be distinguished by their elongated, cat- ...

Greater Spotted Dogfish
The nursehound (''Scyliorhinus stellaris''), also known as the large-spotted dogfish, greater spotted dogfish or bull huss, is a species of Scyliorhinidae, catshark, belonging to the family (biology), family Scyliorhinidae, found in the northeastern Atlantic Ocean. It is generally found among rocks or algae at a depth of . Growing up to long, the nursehound has a robust body with a broad, rounded head and two dorsal fins placed far back. It shares its range with the more common and closely related small-spotted catshark (''S. canicula''), which it resembles in appearance but can be distinguished from, in having larger spots and nasal skin flaps that do not extend to the mouth. Nursehounds have nocturnal habits and generally hide inside small holes during the day, often associating with other members of its species. A benthic predator, it feeds on a range of bony fishes, smaller sharks, crustaceans, and cephalopods. Like other catsharks, the nursehound is oviparous in reproduction ...

Dogfish Bay
Liberty Bay is a narrow inlet extending about 4 miles in a northerly direction from the northwest part of Port Orchard, adjacent to the Kitsap Peninsula in Western Washington. Background The southeastern half of Liberty Bay is very narrow. The shores are low and wooded, and the shoreline is sand and gravel. There are mud flats at the head of the bay and in the small Bight (geography), bight on the south side of the bay. Mud is the predominant bottom characteristic. Tide, Tidal velocities exceed 1 knot at times. The city of Poulsbo, Washington lies at the north end of the bay. Variously named ''Dogfish Bay'', ''Liberty Bay'' and ''Poulsbo Bay''. According to the Kitsap Peninsula Visitor and Convention Bureau's Web site: "Despite pleas of Poulsbo residents, the Washington State Legislature, in 1893 and 1899, refused to change the official title of ''Dogfish Bay'' to Liberty Bay. The present name was adopted through general usage. The original name was a location tie-in to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
