Phosphatic Biomineralization in Scyphozoa (Cnidaria): A Review

Minerals, 2022
Phosphatic biomineralization is unknown in modern species of Scyphozoa (Cnidaria). However, some extinct groups of Scyphozoa, such as conulariids and Sphenothallus, were capable of secreting phosphatic exoskeletons.

Xenia umbellata (Octocorallia): A novel model organism for studying octocoral regeneration ability

Frontiers in Marine Science, 2023
Climate change is leading to phase shifts in coral reefs worldwide. In many biogeographic regions, octocorals are now becoming the most abundant benthic components, due to their environmental resilience and ability to rapidly colonize reef surfaces ...

Neural Cell Type Diversity in Cnidaria

Frontiers in Neuroscience, 2022
Neurons are the fundamental building blocks of nervous systems. It appears intuitive that the human brain is made up of hundreds, if not thousands different types of neurons.

Unexpected Distribution of Chitin and Chitin Synthase across Soft-Bodied Cnidarians

Biomolecules, 2023
Cnidarians are commonly recognized as sea jellies, corals, or complex colonies such as the Portuguese man-of-war. While some cnidarians possess rigid internal calcareous skeletons (e.g., corals), many are soft-bodied.

Learning in Cnidaria: A systematic review

Learning & Behavior, 2021
Using the database Web of Science, a systematic search for literature on learning in Cnidaria, both non-associative and associative, was conducted. Cnidaria comprise hydras, box jellies, (true) jellyfish, corals, and sea anemones, a group of animals ...

Localization of Multiple Jellyfish Toxins Shows Specificity for Functionally Distinct Polyps and Nematocyst Types in a Colonial Hydrozoan

Toxins, 2023
Hydractinia symbiolongicarpus is a colonial hydrozoan that displays a division of labor through morphologically distinct and functionally specialized polyp types.

The abundance of microplastics in cnidaria and ctenophora in the North Sea.

Marine Pollution Bulletin, 2021
Microplastic (MP) ingestion has been widely recorded in aquatic organisms, but few studies focus on cnidarians and ctenophores, which form a significant contribution to marine trophic interactions. Scyphozoans (Cyanea capillata, C.

The rising swarms of jellyfish in Indian waters: the environmental drivers, ecological, and socio-economic impacts

Journal of Water and Climate Change, 2022
A four-decade data of jellyfish aggregation from 1980 to 2020 were taken to discern whether there has been an actual rise in jellyfish swarm in Indian coastal and estuarine waters.

Comparative Aspects of Structure and Function of Cnidarian Neuropeptides

Frontiers in Endocrinology, 2020
Cnidarians are early-branching animals in the eukaryotic tree of life. The phylum Cnidaria are divided into five classes: Scyphozoa (true jellyfish), Cubozoa (box jellyfish), Hydrozoa (species, Hydra and Hydractinia), Anthozoa (sea anemone, corals, and ...
