Echinoderms - Smithsonian Ocean
Echinoderms live in every ocean, even off the coast of Antarctica. Well known as coastal dwellers, they can be found at depths over three miles deep (5,000 meters). Some are stealthy predators, pursuing prey with speed and agility, while others feed on drifting detritus while stuck in place, more similar to a billowing field of ferns.
Diversity of Deep-Sea Echinoderms From Costa Rica - Frontiers
2022年7月14日 · Echinoderms are a highly diverse group and one of the most conspicuous in the deep sea, playing ecological key roles. We present a review about the history of expeditions and studies on deep-sea echinoderms in Costa Rica, including an updated list of species.
Systematics of deep-sea starfish order Brisingida (Echinodermata ...
2024年2月1日 · In this study, we present a comprehensive molecular phylogeny of Brisingida which encompasses the highest taxonomic diversity to date. DNA sequences (COI, 16S, 12S and 28S) were obtained from 225 specimens collected in the global ocean, identified as 58 species spanning 15 of the 17 extant genera.
Mitogenomics provides new insights into the phylogenetic …
2022年3月18日 · To date, the phylogeny of the sea stars and the relationships of deep-sea and shallow water groups have not yet been fully resolved. Here, we recovered five mitochondrial genomes of...

distribution of deep-sea echinoderm species. Depth and bot-tom type are critical factors influencing the structure of epibenthic communities, but habitat studies on echinoderms are still rare (González-Irusta et al. 2012). Consequently, the habitat and microhabitat preferences of Mediterranean deep-
The Conservation of Unique Deep-sea Echinoderm Species
2024年1月17日 · Deep-sea echinoderms, encompassing a diverse group of marine animals like sea cucumbers and brittle stars, face significant challenges due to human-induced activities. Among these threats, deep-sea mining poses a grave concern.
