New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.Brachiopods are able to repair drill holes made in their shells by predatory gastropods. However, in most samples examined, drill hole repair is rare to absent: Presumably the drilling attack is usually fatal to the prey. The shells of short‐looped brachiopod Abyssothyris wyvillei, from deep‐sea dredge samples from two localities in the Tasman Sea, New

Deep-sea echinoderm oxygen consumption rates and an interclass comparison of metabolic rates in Asteroidea, Crinoidea, Echinoidea, Holothuroidea and Ophiuroidea [PDF]
, 2011 Echinoderms are important components of deep-sea communities because their abundance and their activities contribute to carbon cycling. Estimating echinoderm contribution to food webs and carbon cycling is important to our understanding of the ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT Fishers interact daily with coastal environments, which generate a deep understanding of habitat characteristics, species associations and ecological change. Fishers’ ecological knowledge (FEK) is therefore a critical source of insight for marine science, offering observations that uniquely complement scientific data and, when incorporated ...

Ecology and Evolution, Volume 16, Issue 8, August 2026.This study describes a new hexamerous epizoic brittle star species, Gymnolophus sexradia sp. nov., from the South China Sea, which lives on crinoid hosts and exhibits a six‐armed body plan possibly indicating fissiparity. Its vertebral and arm plate structures enhance horizontal flexibility for grasping the host, and phylogenetic analysis based on ...

Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]
, 2004 We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...
