Echinoderms diversity in the Southwestern Atlantic [PDF]

open access: yes, 2015
Studies of biodiversity of echinoderms from South America have increased in recent years. Here we summarize sampling done on three expeditions along the Argentinean coast (35º - 55º S) and near the Antarctic Peninsula.

Potential Invasive Indo‐Pacific Acropora in a Coral Reef of Venezuela: A Contribution to Their Morphological and Molecular Knowledge

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We report the first record of a non‐native hermatypic coral in Venezuela, exhibiting biological traits characteristic of invasive species. The coral is a member of the genus Acropora (Scleractinia: Acroporidae), native to the Indo‐Pacific. This non‐native petrous coral occurred in a reef of the Morrocoy National Park, in the southern Caribbean.

New Brittle Stars (Echinodermata, Ophiuroidea) from the Oligocene of the Mainz Basin, Germany

open access: yesTaxonomy, 2022
The fossil record of the Ophiuroidea is still patchy, especially in the Cenozoic. Only four species have been described from the entire Oligocene, which is in stark contrast to the present-day diversity counting more than 2000 species.

Effects of experimental in situ seabed disturbance on deep‐sea macrofaunal communities of Chatham Rise, Southwest Pacific

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1422-1459, December 2025.
ABSTRACT With the possibility of deep‐sea mining of mineral resources occurring, it is necessary to understand potential impacts on benthic communities. Previous simulated mining experiments revealed direct benthic impacts; however, indirect impacts of sedimentation are not well understood.

New fossils of Jurassic ophiurid brittle stars (Ophiuroidea; Ophiurida) provide evidence for early clade evolution in the deep sea

open access: yesbioRxiv, 2021
Understanding of the evolutionary history of the ophiuroids, or brittle stars, is hampered by a patchy knowledge of the fossil record. Especially the stem members of the living clades are poorly known, resulting in blurry concepts of the early clade ...
