ABOUT

Descriptions(1)

In thin sheets of tightly joined zooids the colonies settle on diverse kinds of substrates. They become uniformly grey in formalin. When fixed this species looks superficially like Symplegma rubra but differs by the gonads. In S. brakenhielmi there is on each side an ovary between 2 testis lobes, both male and female elements maturing at the same time. This species is widely distributed in all oceans and already known in the Western atlantic from Fblorida to Brazil (Rocha & Costa (2005).

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.
