  1. First in this class, and I have absolutely no idea what it is! Posted 2 years ago
    1. They are basically tunicates but of the pelagic types.

      The other tunicates are mostly found on substrates are :

      Bunch of Lollipop Tunicates - Nephtheis fascicularis This Lollipos Tunicates - Nephtheis fascicularis are usually found in a bunch and each lollipop itself is a colony of tunicates! Anilao,Batangas,Geotagged,Lollipop Tunicate,Nephtheis fascicularis,Philippines,Summer

      Tunicates - Eudistoma rhodopyge Not 100%, was given this ID from another forum.<br />

I don't usually see pink-coloured Tunicates, so this one really stands out to me, only saw 2 of them during this trip, size around 8 cm, this is not one organism but a colony of tunicates. Eudistoma rhodopyge,Maldives,Tunicate

      Blue Tunicate - Rhopalaea fusca Like all Tunicates, the Rhopalaea fusca has two tubular openings, known as siphons, through which they draw in and expel water. During their respiration and feeding, they take in water through the incurrent (or inhalant) siphon and expel the filtered water through the excurrent (or exhalant) siphon.  Tunicates are filter feeders.<br />

Note :<br />
Many pictures online, similar to this documenting records from South East Asia identified this as Clavelina coerulea.  However, in the book 'Pacific Tunicata of the United States National Muzeum) has mentioned Clavelina coerulea, indicating Clavelina coerulea is documented only from Japan (North West Pacific).  For  reference, Page 104<br />

''Pyrosoma atlanticum'' is a pelagic species of marine colonial tunicate in the class Thaliacea found in temperate waters worldwide. The name of the genus comes from the Greek words ''pyros'' meaning 'fire' and ''soma'' meaning 'body', referring to the bright bioluminescence sometimes emitted. The specific epithet ''atlanticum'' refers to the Atlantic Ocean, from where the first specimen of the species was collected for scientific description; it was described in 1804 by François Péron, a French.. more
