Thorunna purpuropedis is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae. [2]

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 Enewetak Atoll, Marshall Islands. It has been reported from Japan. [3]

Enewetak Atoll atoll of the Marshall Islands

Enewetak Atoll is a large coral atoll of 40 islands in the Pacific Ocean and with its 664 people forms a legislative district of the Ralik Chain of the Marshall Islands. With a land area total less than 5.85 square kilometres (2.26 sq mi), it is no higher than 5 meters and surrounds a deep central lagoon, 80 kilometres (50 mi) in circumference. It is the second-westernmost atoll of the Ralik Chain and is 305 kilometres (190 mi) west from Bikini Atoll.

Marshall Islands country in Oceania

The Marshall Islands, officially the Republic of the Marshall Islands, is an island country and a United States associated state near the equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 53,158 people is spread out over 29 coral atolls, comprising 1,156 individual islands and islets.
