Sund Rock
Sund Rock is a designated conservation area on the U.S. state of Washington's Hood Canal. The area is known for abundant and diverse life, including but not limited to Lingcod, Giant Pacific Octopus, Wolf Eel, as well as nudibranch, anemone, and sea cucumber. The area is well known to regional scuba Scuba may refer to: * Scuba diving ** Scuba set, the equipment used for scuba (Self-Contained Underwater Breathing Apparatus) diving * Scuba, an in-memory database developed by Facebook * Submillimetre Common-User Bolometer Array, either of two in ... divers, especially for its two major walls, known colloquially as the north and south walls. These walls have depths , depending upon the tide. Several other walls exist, some going down beyond in depth. One of these is called "fish pen wall." Additional features include the "fish bowl"—a reef-like area full of life—a large sunken boat just to the north of the north wall, and a small wrecked boat between the north and south wal ...

Lingcod
The lingcod or ling cod (''Ophiodon elongatus''), also known as the buffalo cod or cultus cod, is a fish of the greenling family Hexagrammidae. It is the only extant member of the genus ''Ophiodon. ''A slightly larger, extinct species, '' Ophiodon ozymandias'', is known from fossils from the Late Miocene of Southern California.'' ''Ophiodon elongatus'' is native to the North American west coast from Shumagin Islands in the Gulf of Alaska to Baja California, Mexico. It has been observed up to a size of and a weight of . It is spotted in various shades of gray. The lingcod is a popular eating fish, and is thus prized by anglers. Though not closely related to either ling or cod, the name "lingcod" originated because it somewhat resembles those fish. Around 20% of lingcods have blue-green to turquoise flesh.p. 298 The colour is destroyed by cooking. The colour may be due to biliverdin, but this has not been established beyond doubt. Distribution and lifecycle Lingcod are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enteroctopus Dofleini
The giant Pacific octopus (''Enteroctopus dofleini''), also known as the North Pacific giant octopus, is a large marine cephalopod belonging to the genus '' Enteroctopus''. Its spatial distribution includes the coastal North Pacific, along Mexico (Baja California), The United States (California, Oregon, Washington, and Alaska), Canada (British Columbia), Russia, Eastern China, Japan, and the Korean Peninsula. It can be found from the intertidal zone down to , and is best adapted to cold, oxygen-rich water. It is the largest octopus species, based on a scientific record of a individual weighed live. Etymology The specific name ''dofleini'' was chosen by Gerhard Wülker in honor of German scientist Franz Theodor Doflein. It was moved to genus '' Enteroctopus'' by Eric Hochberg in 1998. Description Size ''E. dofleini'' is distinguished from other species by its large size. Adults usually weigh around , with an arm span up to .

Wolf Eel
The wolf eel (''Anarrhichthys ocellatus'') is a species of marine ray-finned fish belonging to the family Anarhichadidae, the wolf fishes. It is found in the North Pacific Ocean. Despite its common name and resemblance, it is not a true eel. It is the only species in the monotypic genus ''Anarrhichthys''. Taxonomy The wolf eel was first formally described in 1855 by the American physician and ichthyologist William Orville Ayres with the type locality given as San Francisco Bay in California. It is the only species in the monotypic genus ''Anarrichthys'', which was also described by Ayres in 1855. This is one of two genera in the family Anarhichadidae, the other being ''Anarhichas''. Etymology The Wolf eel’s genus name ''Anarrhichthys'' combines the wolffish genus ''Anarhichas'', as this taxon has a similar head shape to the wolffishes, and ''ichthys'', which means “fish”. The Specific name (zoology), specific name ''ocellatus'' means “ocellated”, a reference to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", or "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known.Ocean Portal (2017)A Collage of Nudibranch Colors Smithsonian National Museum of Natural History. Retrieved 17 April 2018. The word "nudibranch" comes from the Latin "naked" and the Ancient Greek () "gills". Nudibranchs are often casually called sea slugs, as they are a family of opistobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic ''Sacoglossa'' and the colourful Aglajidae, are often confused with nudibranchs. Distribut ...

Sea Anemone
Sea anemones are a group of predation, predatory marine invertebrates of the order (biology), order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and ''hydra (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holothuroidea
Sea cucumbers are echinoderms from the class Holothuroidea (). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. The number of holothurian () species worldwide is about 1,717, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as '' trepang'', ''namako'', ''bêche-de-mer'', or ''balate''. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...
