Jorunna
''Jorunna'' is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae. Biology ''Jorunna'' species are usually camouflaged to match the sponges they feed on, which in many cases belong to the family Chalinidae. It is likely that many undescribed species exist.Rudman, W.B., 1999 (January 6''Jorunna pantherina'' (Angas, 1864). n/nowiki> Sea Slug Forum. Australian Museum, Sydney.

Port Jackson
Port Jackson, consisting of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove and Parramatta Rivers, is the ria or natural harbour of Sydney, New South Wales, Australia. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. Port Jackson, in the early days of the colony, was also used as a shorthand for Sydney and its environs. Thus, many botanists, see, e.g, Robert Brown's ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', described their specimens as having been collected at Port Jackson. Many recreational events are based on or around the harbour itself, particularly Sydney New Year's Eve celebrations. The harbour is also the starting point of the Sydney to Hobart Yacht ...

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
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 Slug
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species implies that these animals are under constant threat of predators, but the color can serve as a warning to other animals of the sea slug's toxic stinging cells (nematocysts) or offensive taste. Like all gastropods, they have small, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sensory te ...

George French Angas
George French Angas (25 April 1822 – 4 October 1886), also known as G.F.A., was an English explorer, naturalist, painter and poet who emigrated to Australia. His paintings are held in a number of important Australian public art collections. He was the eldest son of George Fife Angas, who was prominent in the early days of the colonisation of South Australia. Biography He was born in Newcastle upon Tyne, England, the eldest son of George Fife Angas, prominent in the establishment of the new colony of South Australia. Despite showing remarkable talent in drawing, he was placed in a London business house by his father. He left on a tour of Europe and in 1842 published his first book, ''"Rambles in Malta and Sicily"''. As a result of this experience, he turned his back on the world of commerce, and directed his training towards a study of natural history, anatomical drawing and lithography. Embarking on his travels, he was soon to find his acquired skills extremely useful. Ang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discodorididae
Discodorididae is a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea.Bouchet, P. (2011). Discodorididae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=1761 on 2011-08-23 Species in this family belong to the cryptobranch dorid nudibranchs, i.e. they are able to retract their gills into a gill pocket (cryptobranch = hidden gills). Most are small and hard to identify. Most are thought to feed at night on sponges, while during the day they search for dark areas or remain hidden under rocks. One example of a discodoridid is the "Pacific sea lemon" or "speckled sea lemon", ''Peltodoris nobilis'', which occurs off the coast of British Columbia to Baja California from low-tide waters to a depth of about 200 m. Not only is this species yellow with a bumpy surface, but it also gives off a strong fruity citrus smell when handled, adding to its resemblance ...

Doridoidea
Doridoidea, commonly known as dorid nudibranchs (and previously known as the taxon Cryptobranchia), are a taxonomic superfamily of medium to large, shell-less sea slugs, marine gastropod mollusks in the clade Doridacea, included in the clade Nudibranchia. Etymology The word "Doridoidea" comes from the generic name ''Doris'', which was in turn copied from the name of the sea nymph, Doris, in Greek mythology. Families According to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), families within the superfamily Doridoidea include: * Actinocyclidae O'Donoghue, 1929 * Chromodorididae Bergh, 1891 * Discodorididae Bergh, 1891 * Dorididae Rafinesque, 1815 Changes later than 2005 The family Cadlinidae Bergh, 1891 was considered a synonym of the Chromodorididae. Research by R.F. Johnson in 2011 has shown that ''Cadlina'' does not belong to the family Chromodorididae. She has therefore brought back the name ''Cadlinidae'' from synonymy with ''Chromodorididae''. The chromodori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
