New species of Didemnidae (Tunicata: Ascidiacea) from the tropical coast of Brazil.
The family Didemnidae includes 20% of all known ascidians with six genera in the Atlantic. Here, we describe five new species in the Didemnidae from central coastal Brazil. Four species are in the genus Didemnum and were found in Bahia (D. aurantium, D. flammacolor, D. lambertae, D. longigaster), while one Diplosoma (D. citrinum) was found both in Bahia and Espírito Santo.
متن کاملHuman-mediated global dispersion of Styela plicata (Tunicata, Ascidiacea)

Its origin is uncertain, given that it has already been identified in several oceans since it was first described, showing a very broad geographical distribution. Although S. plicata has been historically classified as a cosmopolitan species, in the past few deca...

متن کاملCorrelation between granulocytes and tunic cuticle of Ciona intestinalis (Tunicata, Ascidiacea) as evaluated by microscopy
The tunic is a peculiar integumentary tissue covering the epidermis of ascidians and other tunicates. It is an extracellular matrix whose outermost surface is revealed to be a continuos layer called tunic cuticle, composed of electron dense fibrous materials. Mechanisms occurring during the growth of the animal after metamorphosis, must assure the maintenance of the thin tunic cuticle density a...
متن کاملThe role of Didemnum perlucidum F. Monniot, 1983 (Tunicata, Ascidiacea) in a marine fouling community
Didemnum perlucidum is a colonial ascidian that is cryptogenic in southern Brazil but introduced in many regions around the world. It is common in ports and marinas where it may form large colonies although its role in fouling communities is poorly understood. The goal of this study was to evaluate the role of D. perlucidum in a marine fouling community comprised mainly of non-indigenous specie...
