Versuriga

The generic name Versuriga was derived from the genus Versura, originally described by Ernst Haeckel. The type species of the genus, Versura palmata, was found to instead be a specimen of Mastigias papua; the other species within Versura were regarded as doubtful and unidentifiable, rendering the genus name invalid. Paul Lassenius Kramp proposed Versuriga as a result in order to assign a genus to the previously described Crossostoma anadyomene, which Haeckel had earlier referred to Versura due to Crossostoma having been preoccupied.[7] Versura is derived from the Latin versurus, meaning "about to turn (around)".

The specific epithet derives from the Ancient Greek word ἀναδυομένος (anaduoménos), meaning "emerging, surfacing".

Versuriga, like other members of the phylum Cnidaria, has its most notable feature being its umbrella shaped bell, reaching a diameter of up to 600 mm. Rather than being completely round or flat, its bell is made up of pointed grooves, growing in length closer to the center. Its body is mostly made up of umbrella and hemispherical shapes. This includes its muscular fields, which are also subumbrella shaped, as well as its canal features.[3] Another of its identifiable features is its coloration, ranging from semi-translucently pink and purple at its center, eventually transitioning into a brown color.[3] To distinguish between the Versuriga and other similar species, there are a few particular features to examine. There is a distinct difference between the shape of female and male genital double somites. Also, the structures of the appendages are discernible, specifically the antennae, maxillipeds, and legs. Between the female and male Versuriga, there are also morphological differences. Some of these differences include the male body being more slender, and that certain parts of the legs differ, in free segment length and endopod length.[4]

Versuriga is a very rare sight, and thus has seldom been studied or recorded. Until recently, the majority of Scyphozoa sightings, the class that Versuriga belongs to, were unreliable as they were mostly first hand accounts rather than scientific recordings.[2] However, it has been found off the coasts of Malaysia, Philippines, Indonesia, and Australia, Vietnam.[2] Versuriga is an occupant of nearshore waters, where its food is most abundant.[3] Recent studies in regards to Versuriga distributions in the Philippines found that Versuriga had highest abundance in Leyte Gulf, which was the location with the highest observed mean temperatures. This suggests that Versuriga may prefer or best thrive in warmer climates.[5]
