Descriptions(1)

This species often recorded from the tropical Pacific Ocean was already noticed from Brazil by Rocha & Monniot (1995). It was found again at several times from other Brazilian localities (Paiva et al 2015). This well known species is orange with a characteristic granular surface. The zooid has no languet and a single testis lobe. The larva has 3 adhesive papillae and 4 pairs of lateral ectodermal ampullae. Its geographic origin is not known.

Ascidians (Tunicata) of the French Guiana Expedition

checklist

This dataset contains the digitized treatments in Plazi based on the original journal article Monniot, Françoise (2016): Ascidians (Tunicata) of the French Guiana Expedition. Zootaxa 4114 (3): 201-245, DOI: 10.11646/zootaxa.4114.3.1

Abstract

Ascidians were collected along the shore of Iles du Salut and deeper on the slope in a program of evaluation of the biodiversity in Guiana. Most of the samples belong to already known species from the Caribbean area and Brazilian coast. The colonial forms dominate. The 6 new species have been dredged deeper than 50m but not found by SCUBA divers. In spite of an intensive sampling, the ascidian diversity in Guiana is low with 36 species recorded. This is the result of the abundance of sediment suspended in the water and uniformly deposited on all substrates which affects filtration rate and limits the settling of the ascidian larvae.
