Jangoux M. 1981. On Tremaster verrill, 1879, an odd genus of recent starfish (Echinodermata: Asteroidea), in Lawrence J.M. (Ed.), Echinoderms. Proceedings of the International Echinoderm Conference, Rotterdam : Salem, NH, A.A. Balkema ; Distributed in USA & Canada by MBS: 155-163
Résumé [+]
[-]
The genus Tremaster has several primitve features and show clear relationships with middle Jurassic fossils. Tremasters are unique among recent forms in having internal calcified duct in each interradius. Each duct opens upwards and downwards into the surrounding medium through two interradial apertures. Owing to the presence of these ducts, asteroids presumably are able to change their body shape while having their margin closely appressed to the substrate. Gametes are released into these ducts which can be used as brood chambers. Such internal calcified ducts are assumed to be modified interradial speta.

Résumé [+]
[-]
A molecular phylogenetic analysis of the genus Hippasteria, rooted against Evoplosoma, has provided the basis for taxonomic revisions and provided insight into the biogeography of a widely occurring, cold-water group of corallivorous asteroids. Herein, we describe three new species, Hippasteria mcknighti sp. nov., Hippasteria muscipula sp. nov., and Hippasteria tiburoni sp. nov., from deep-water settings. Additionally, in light of taxonomic changes, we further elaborate on distribution data for multiple species. Range extensions for Hippasteria phrygiana and Hippasteria californica are included. Discussions about biogeography, cladogenic events, and morphology are also presented.(c) 2014 The Linnean Society of London
