Phylum Echinodermata*

open access: yesZootaxa, 2007
The Phylum Echinodermata, comprising approximately 7,000 living species, and 13,000 fossil species, is epitomized by the familiar sea star, a universal symbol of the marine realm.  This distinctive group of animals may be briefly defined as possessing a skeleton of calcium carbonate in the form of calcite; a unique water-vascular system which mediates ...

Echinodermata

open access: yes, 1982
Echinodermata as Deuterostomes The extant Deuterostomia (“second mouth”) are usually defined as animals in which the mouth develops from a second opening in the embryo, opposite to the initial opening, the blastopore, of the rudimentary gut. In addition the coelom develops by enterocoely, or pouching from the primitive gut.

The complete mitochondrial genome sequence of Stichopus variegatus (Echinodermata: Holothuroidea) and phylogenetic studies of Echinodermata

open access: yesMitochondrial DNA. Part B. Resources, 2019
At present, there exist some confusing issues on the species classification and phylogeny in Echinodermata. In this study, we first determined and described the complete mitochondrial genome of Stichopus variegatus. The complete mitogenome sequence had a

Riding the Storm: Microeukaryote Community Responses to Hurricane Disturbance. [PDF]

open access: yesJ Eukaryot Microbiol
ABSTRACT Sandy beaches are dynamic ecosystems where terrestrial and marine organisms coexist, resulting in diverse communities where microeukaryotes (protists, microalgae, and meiofauna) are key drivers. Understanding their diversity patterns and responses to stressors is essential for elucidating ecological processes, yet information on this subject ...

Echinodermata

open access: yes, 2017
This chapter describes the taxonomy of Echinodermata, a diverse group of organisms consisting systematically of five classes including sea stars (Asteroidea), brittle stars (Ophiuroidea), sea urchins (Echinoidea), sea cucumbers (Holothuroidea), and feather stars (Crinoidea). It covers their life cycle, ecology, and general morphology.
