Ardeadoris averni is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Chromodorididae. [2] It was transferred to the genus Ardeadoris on the basis of DNA evidence. [3]

In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

Sea slug group of marine invertebrates with varying levels of resemblance to terrestrial slugs

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 actually gastropods, i.e. they are sea snails 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.

Nudibranch order of molluscs

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", and "dragon". Currently, about 3,000 valid species of nudibranchs are known.

Distribution

This species was described from the Capricorn Group, Great Barrier Reef, Queensland, Australia. It is also found in the Western Pacific Ocean from Papua New Guinea and the Philippines. [4]

Capricorn and Bunker Group Queensland, Australia

The islands and reefs of the Capricorn and Bunker Group are situated astride the Tropic of Capricorn at the southern end of the Great Barrier Reef, approximately 80 kilometres east of Gladstone, which is situated on the central coast of the Gladstone Region, Queensland, Australia.

Great Barrier Reef Coral reef system off the east coast of Australia, World Heritage Site

The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world. The Queensland National Trust named it a state icon of Queensland.

Queensland North-east state of Australia

Queensland is the second-largest and third-most populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. To its north is the Torres Strait, with Papua New Guinea located less than 200 km across it from the mainland. The state is the world's sixth-largest sub-national entity, with an area of 1,852,642 square kilometres (715,309 sq mi).

Description

Ardeadoris averni is white with a bright red border to the mantle. The gills and rhinophores are white with red lines. It grows to 55 mm in length. [5] [6] [7]
