A sticky thicket of glue cells: A comparative morphometric analysis of colloblasts in 20 species of comb jelly (phylum Ctenophora)

open access: yesCiencias Marinas, 2020
Ctenophores in the class Tentaculata are distinct from Cnidarians in that they use sticky, not stinging, tentacles to capture and subdue their prey.

Morphological and dietary changes encoded in the genome of Beroe ovata, a ctenophore-eating ctenophore. [PDF]

open access: yesNAR Genom Bioinform
Abstract As the sister group to all other animals, ctenophores (comb jellies) are important for understanding the emergence and diversification of numerous animal traits. Efforts to explore the evolutionary processes that promoted diversification within Ctenophora are hindered by undersampling genomic diversity within this clade.

Questioning the rise of gelatinous zooplankton in the World's oceans [PDF]

open access: yes, 2012
During the past several decades, high numbers of gelatinous zooplankton species have been reported in many estuarine and coastal ecosystems. Coupled with media-driven public perception, a paradigm has evolved in which the global ocean ecosystems are ...

The early expansion and evolutionary dynamics of POU class genes. [PDF]

open access: yes, 2014
The POU genes represent a diverse class of animal-specific transcription factors that play important roles in neurogenesis, pluripotency, and cell-type specification. Although previous attempts have been made to reconstruct the evolution of the POU class,
