Omnidirectional propulsion in a metachronal swimmer. [PDF]
Aquatic organisms often employ maneuverable and agile swimming behavior to escape from predators, find prey, or navigate through complex environments. Many of these organisms use metachronally coordinated appendages to execute complex maneuvers. However,

Recording cilia activity in ctenophores: effects of nitric oxide and low molecular weight transmitters [PDF]
Cilia are the major effectors in Ctenophores, but very little is known about their transmitter control and integration. Here, we present a simple protocol to monitor and quantify cilia activity and provide evidence for polysynaptic control of cilia ...

Reproductive success of inbred strain MV31 of the ctenophore Mnemiopsis leidyi in a self-sustaining inland laboratory culture system [PDF]
Ctenophores are an attractive phylogenetic lineage for studying animal evolution due to their early divergence from other metazoans. Among Ctenophora, Mnemiopsis leidyi is a model system for developmental, cellular, molecular genetic, and evolutionary ...

Early Animal Origin of BACE1 APP/Aβ Proteolytic Function [PDF]
Alzheimer’s disease is characterized, in part, by the accumulation of β-amyloid (Aβ) in the brain. Aβ is produced via the proteolysis of APP by BACE1 and γ-secretase.

Evolution of g-type lysozymes in metazoa: insights into immunity and digestive adaptations [PDF]
Exploring the evolutionary dynamics of lysozymes is critical for advancing our knowledge of adaptations in immune and digestive systems. Here, we characterize the distribution of a unique class of lysozymes known as g-type, which hydrolyze key components

From ctenophores to scyphozoans: parasitic spillover of a burrowing sea anemone [PDF]
Most host-parasite associations are explained by phylogenetically conservative capabilities for host utilization, and therefore parasite switches between distantly related hosts are rare.

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)
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

New data on the ctenophore Beroe ovata, an invader to the Caspian Sea
Aim. Analysis of new data on populations of invasive ctenopfores Вeroe ovata and Mnemiopsis leidyi in the Caspian Sea and assessment of adaptation of B. ovata to new habitat conditions.Material and methods. The data was obtained in the Dagestan sector of
