Molecular phylogeny of extant Holothuroidea (Echinodermata) [PDF]

open access: yesMolecular Phylogenetics and Evolution, 2017
Sea cucumbers (Holothuroidea) are a morphologically diverse, ecologically important, and economically valued clade of echinoderms; however, the understanding of the overall systematics of the group remains controversial. Here, we present a phylogeny of extant Holothuroidea assessed with maximum parsimony, maximum likelihood, and Bayesian approaches ...

The catecholaminergic nerve plexus of Holothuroidea [PDF]

open access: yesZoomorphology, 2010
Catecholamines have been extensively reported to be present in most animal groups, including members of Echinodermata. In this study, we investigated the presence and distribution of catecholaminergic nerves in two members of the Holothuroidea, Holothuria glaberrima (Selenka, 1867) (Aspidochirotida, Holothuroidea) and Holothuria mexicana (Ludwig, 1875)

A Case of Holothuroidea-like Erythrocytes

Journal of Biomedical Research & Environmental Sciences, 2023
Ektacytometric examination of red blood cells with morphological anomaly is presented. Confocal microscopy of the blood from the patient N. shows the abundance of RBCs in the form of representatives of the Holothuroidea. RBCs from control patients exhibited an elliptical diffraction pattern whereas patient’s N.

System of the class Holothuroidea

Paleontological Journal, 2012
Various interpretations of the holothurian system and phylogeny are critically reviewed and the main characters that form the basis of the existing systematics of this group are analyzed. A system of holothurians based on thorough analysis of their morphology and anatomy is proposed.
