Approaches to the ethology of hydroids and medusae (Cnidaria, Hydrozoa)

Scientia Marina, 2000
The behavioural patterns of 26 species of Antho- and Leptomedusae (with or without medusa stage) were investigated by video recordings. The analysed activities were: answers to mechanical stimuli, prey capture and ingestion, digestion, egestion, and ...

Signaling Mechanism of Budding, Proliferation, and Tissue Regeneration in Cnidaria [PDF]

Current Issues in Molecular Biology
Phylum Cnidaria occupies an early branching position in the evolution of eukaryotes, establishing both close and distant relationships with most other eukaryotic metazoans. Budding encompasses the complete processes of cell proliferation, differentiation,

Not Drug-like, but Like Drugs: Cnidaria Natural Products

Marine Drugs, 2021
Phylum Cnidaria has been an excellent source of natural products, with thousands of metabolites identified. Many of these have not been screened in bioassays.

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 ...

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.

Transposon-derived transcription factors across metazoans

Frontiers in Cell and Developmental Biology, 2023
Transposable elements (TE) could serve as sources of new transcription factors (TFs) in plants and some other model species, but such evidence is lacking for most animal lineages. Here, we discovered multiple independent co-options of TEs to generate 788

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.

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 ...

Check List of Iran marine Cnidarians (Animalia, Cnidaria) [PDF]

Iranian Journal of Animal Biosystematics, 2020
There is an urgent need for quality control of marine species data published in domestic journals and open access databases. We extracted 149 accepted Cnidarian species after the quality control process on available published records on the OBIS data ...
