Suspected chemoreceptors in coelenterates and ctenophores
Microscopy Research and Technique, 1992 AbstractChemoreceptors in coelenterates and ctenophores have not been identified with certainty. Among prospective chemoreceptive cells are the sensory nerve cells, the cnidocyst bearing cnidocytes, and the epitheliomuscular cells that are likely to be involved in feeding or aggression. Both behaviors are mediated by coordinated chemical and mechanical

Rapid physiological integration of fused ctenophores
Current BiologyThe mechanisms by which organisms recognize the 'self' from the 'non-self' remain poorly understood. Moreover, the capability of transplanted tissue to functionally integrate is unclear in many organisms. Here, we report that two injured Mnemiopsis leidyi individuals, a species of planktonic animals known as comb jellies or ctenophores, are capable of ...

Neural connectome of the ctenophore statocyst. [PDF]
ElifeAbstract Ctenophores possess a unique gravity receptor (statocyst) in their aboral organ formed by four clusters of ciliated balancer cells that collectively support a statolith. During reorientation, differential loads on the balancer cilia lead to altered beating of the ciliated comb rows to elicit turns.

iScience, 2021 Summary: Ctenophores are a group of predatory macroinvertebrates whose controversial phylogenetic position has prompted several competing hypotheses regarding the evolution of animal organ systems. Although ctenophores date back at least to the Cambrian,

A late-surviving stem-ctenophore from the Late Devonian of Miguasha (Canada)
Scientific Reports, 2021 Like other soft-bodied organisms, ctenophores (comb jellies) produce fossils only under exceptional taphonomic conditions. Here, we present the first record of a Late Devonian ctenophore from the Escuminac Formation from Miguasha in eastern Canada. Based

Sponges, ctenophores, and the statistical significance of syntenies. [PDF]
Mol Biol EvolShared fusions between ancestral chromosomal linkage groups have previously been used to support phylogenetic groupings, notably sponges with cnidarians and bilaterians to the exclusion of ctenophores, rendering ctenophores the sister group to all other animals.

Diffusion tubes: a method for the mass culture of ctenophores and other pelagic marine invertebrates [PDF]
PeerJ, 2020 The culture of pelagic marine invertebrates, especially the ctenophore Mnemiopsis leidyi, has been demonstrated in past studies dating back to the 1960s; however, the mass culture of delicate pelagic invertebrates has remained elusive. By using a pair of
