Frontiers in Neuroanatomy, 2022 Cubomedusae, or box jellyfish, have a complex visual system comprising 24 eyes of four types. Like other cnidarians, their photoreceptor cells are ciliary in morphology, and a range of different techniques together show that at least two of the eye types—

β-Catenin–dependent mechanotransduction dates back to the common ancestor of Cnidaria and Bilateria
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Besides genetic regulation, mechanical forces have been identified as important cues in numerous developmental processes. Mechanical forces can activate biochemical cascades in a process called mechanotransduction.

Scientia Marina, 2000 Based on live specimens of Nemalecium lighti collected in the coasts of La Réunion (Indian Ocean) and São Sebastião (Southeastern coast of Brazil) and kept in the laboratory, we observed the release of short-lived medusoids. The gonangia pass through six

Linear Mitochondrial Genome in Anthozoa (Cnidaria): A Case Study in Ceriantharia
Scientific Reports, 2018 Sequences and structural attributes of mitochondrial genomes have played a critical role in the clarification of relationships among Cnidaria, a key phylum of early-diverging animals.

Ecography, EarlyView.The core–periphery hypothesis (CPH) predicts that genetic diversity is greatest at the centre and lowest at the edges of a species' distribution because genetic diversity is a function of a species' abundance, which is also expected to be greatest at the centre and lowest at the edges of the distribution. Variants of the CPH include the ‘Ramped North' (

Scientia Marina, 2000 Cnidocyst nomenclature is based on the structure of the tubule and its armature as viewed in the light microscopy (LM). Investigations utilising optically improved LM and scanning electron microscopy have revealed some errors in the interpretation of the

Small
Evolutionary Applications, 2022 AbstractAs fundamental components of RNA silencing, small RNA (sRNA) molecules ranging from 20 to 32 nucleotides in length have been found as potent regulators of gene expression and genome stability in many biological processes of eukaryotes. Three major small RNAs are active in animals, including the microRNA (miRNA), short interfering RNA (siRNA ...

Two Distinct, Geographically Overlapping Lineages of the Corallimorpharian Ricordea Florida (Cnidaria: Hexacorallia: Ricordeidae) [PDF]
, 2011 We examined the genetic variation of the corallimorpharian Ricordea florida; it is distributed throughout the Caribbean region and is heavily harvested for the marine aquarium trade. Eighty-four distinct individuals of R. florida were sequenced from four

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