The first identification of complete Eph-ephrin signalling in ctenophores and sponges reveals a role for neofunctionalization in the emergence of signalling domains

BMC Evolutionary Biology, 2019
Background Animals have a greater diversity of signalling pathways than their unicellular relatives, consistent with the evolution and expansion of these pathways occurring in parallel with the origin of animal multicellularity.

First records of two lobate comb-jellies (Ctenophora) from the Pakistani coast [PDF]

Check List, 2015
The knowledge on the comb-jellies faunistics along the southern Asian coast is very scarce. For some countries such as Pakistan there are no previous formal records of ctenophores. This study is a first survey to the group diversity along Pakistani coast,

Cambrian Sessile, Suspension Feeding Stem-Group Ctenophores and Evolution of the Comb Jelly Body Plan [PDF]

, 2019
The origin of ctenophores (comb jellies) is obscured by their controversial phylogenetic position, with recent phylogenomic analyses resolving either sponges or ctenophores as the sister group of all other animals.

Three Distinct Views of Deep Pelagic Community Composition Based on Complementary Sampling Approaches

Frontiers in Marine Science, 2022
Our perception of deep-sea communities has evolved as various sampling approaches have captured different components of deep-sea habitats. We sampled midwater zooplankton assemblages in Monterey Bay, California to quantify community composition ...

Environmental drivers and ecological implications of a ctenophore swarm: a case study from the Bay of Bengal, northern Indian Ocean

Journal of Water and Climate Change, 2023
Ctenophores are quick responders to coastal environmental changes and play a crucial role in marine food web dynamics. We report the environmental drivers of a ctenophore swarm (Pleurobrachia spp.) and associated ecological changes in estuarine and ...

Non-excitable fluorescent protein orthologs found in ctenophores [PDF]

, 2016
Background: Fluorescent proteins are optically active proteins found across many clades in metazoans. A fluorescent protein was recently identified in a ctenophore, but this has been suggested to derive from a cnidarian, raising again the question of ...

Zoology: At Last an Exit for Ctenophores [PDF]

Current Biology, 2016
Ctenophores, one of the most basal branches in the tree of life, have been found to have a through-gut, complete with mouth and anus. Basal animals are surprisingly complex and simplification has been rampant in animal evolution.

Gelatinous zooplankton net-collected in the Gulf of Maine and adjacent submarine canyons: new species, new family (Jeanbouilloniidae), taxonomic remarks and some parasites

Scientia Marina, 2006
A systematic account is provided of the siphonophores, medusae, ctenophores, molluscs and salps net-collected in basins of the Gulf of Maine and adjacent canyons during three cruises carried out in September 2002, 2003 and 2004.

Alternative neural systems: What is a neuron? (Ctenophores, sponges and placozoans)

Frontiers in Cell and Developmental Biology, 2022
How to make a neuron, a synapse, and a neural circuit? Is there only one ‘design’ for a neural architecture with a universally shared genomic blueprint across species?
