The cause of colouration in the ctenophore Beroë cucumis [PDF]

open access: yesCurrent Biology, 2005
Ctenophores are famed for the spectacular iridescence of their comb-rows, but the cause of this bright colouration has never been found. The colour of any given part of a ctenophore comb-row changes as the combs in that region beat and, thus, the angle between each comb and an observer changes.

The Hox-TALE has been wagging for a long time [PDF]

open access: yes, 2014
Hox and TALE proteins interact in a sea anemone, just as they do in flies and mice, indicating that the Hox-TALE system originated very early in animal evolution.Peer ...

Accounting for Intra‐ and Intergenomic Sequence Variation in Reference Barcodes Improves eDNA Metabarcoding Biodiversity Assessment

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Environmental DNA (eDNA) metabarcoding can rapidly characterise biodiversity, yet its accuracy and effectiveness are limited by incomplete DNA barcode reference databases. We evaluated how comprehensive reference databases that include sequence variation within genomes (intragenomic) and across individuals and species (intergenomic) improve ...

A Dynamic Foraging Habitat Distribution Estimate for Green Turtles in the Great Barrier Reef

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We develop telemetry‐based habitat models with boosted regression trees to identify the environmental characteristics underpinning foraging habitat suitability for green turtles in the Great Barrier Reef region. We then predict potentially suitable foraging areas for green turtles in the Great Barrier Reef region.

Non-native brittle star interactions with native octocoral epizoites: an endemic benthic ctenophore in peril?

open access: yes, 2021
Widespread and large populations of the non-native eastern Pacific ophiuroid brittle star Ophiothela mirabilis now occur in southeastern Florida, extending the range of this recently introduced species from southern Brazil northward to the eastern ...

The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa

open access: yesEvoDevo, 2010
Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...
