Murphydoris is a genus of sea slugs, specifically dorid nudibranchs, marine gastropod molluscs in the family Goniodorididae.
Murphydoris singaporensisSigurdsson, 1991 is the type species of the genus Murphydoris. [1] The generic name Murphydoris was created to honor the zoologist and ecologist D. H. Murphy, who is on the staff at the National University of Singapore. [1]
The genus Murphydoris lacks peri-anal ctenidia (comb-like respiratory gills); its rhinophores are non-lamellate and its radula formula is n x 1.1.0.1.1. The lateral teeth are unicuspid (= with a single tapering point) with 12 denticles and the marginal teeth are bicuspid. [1]
The type locality for Murphydoris singaporensis is mangroves between Kranji and Sungei Buloh Wetland Reserve in Singapore. [1]
Murphydoris singaporensis was firstly collected by Jon B. Sigurdsson, and was described as a new species in 1991. [1]
This is a small nudibranch with a body length of 5 mm and a body width of 2 mm. It was found along the coast of Singapore, between colonies of the bryozoan Sundanella sibogae (order Ctenostomatida).
In this animal, the mantle is colorless and translucent, showing the colors of the internal organs. The surface of the mantle shows irregular dark reddish-brown blotches. Behind the rhinophores there is a large horse shoe shaped spot. There are no mantle papillae in front of the non-lamellate, non-retractile rhinophores. The mantle ridge is situated at either side of the anus and is reduced to three pairs of bifid tentacles. Its penis is armed with many spines. It lays its spawn in loose white coils. [1]
When these nudibranchs respond to a threat, they adopt a defensive posture: they flatten their body allowing numerous spicules to penetrate through the body wall, so that the nudibranch assumes the aspect of a hedgehog, covered in spines. The numerous glands on the body wall also probably contribute to the effectiveness of this defensive posture. [1]
Other species have been tentatively placed in Murphydoris, but have not yet been named and are undescribed species: [2]

Ardeadoris angustolutea is a species of colourful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Chromodorididae. It was transferred to the genus Ardeadoris on the basis of DNA evidence.
Nembrotha aurea is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Polyceridae. It was first described in 2008.
Samla riwo is a species of sea slug, an aeolid nudibranch, a marine heterobranch mollusc in the family Samlidae.

Tyrannodoris is a genus of sea slugs, polycerid nudibranchs, marine gastropod molluscs in the family Polyceridae. Most of these species were formerly considered to belong to the genus Roboastra. They are carnivorous, feeding on other species of nudibranch, especially similar looking species of Tambja.
Janolus flavoanulatus is a sea slug species. The specific name is derived from Latin words flavus (“yellow”) and anulatus (“ringed”). These soft-bodied mollusks are known for their extraordinary colors and prominent forms. The first description of this species was reported by researcher Terry Gosliner, a leading researcher in the evolutionary history of nudibranchs. Upon his conducted research in the Philippines, Gosliner named Janolus flavoanulatus for its yellow ring around its cerata.
