Biochemical and Toxinological Characterization of Venom from Macrorhynchia philippina (Cnidaria, Hydrozoa)

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
Macrorhynchia philippina is a colonial benthic hydroid from the Class Hydrozoa (Phylum Cnidaria) distributed in the tropical and subtropical marine waters from Atlantic Ocean, Indo‐Pacific, and Mozambique. Its colonies somewhat resemble plants, causing confusion in the bathers who accidentally touch the animal. Acute burning/local pain, edema, erythema,

Marine artificial light at night: An empirical and technical guide

Methods in Ecology and Evolution, Volume 12, Issue 9, Page 1588-1601, September 2021., 2021
Abstract The increasing illumination of our world by artificial light at night (ALAN) has created a new field of global change research with impacts now being demonstrated across taxa, biological ranks and spatial scales. Following advances in terrestrial ecology, marine ALAN has become a rapidly growing research area attracting scientists from across ...

Evolution of glial wrapping: A new hypothesis

Developmental Neurobiology, Volume 81, Issue 5, Page 453-463, July/August 2021., 2021
Abstract Animals are able to move and react in numerous ways to external stimuli. Thus, environmental stimuli need to be detected, information must be processed and finally an output decision must be transmitted to the musculature to get the animal moving.

Indoles induce metamorphosis in a broad diversity of jellyfish, but not in a crown jelly (Coronatae). [PDF]

PLoS ONE, 2017
Many animals go through one or more metamorphoses during their lives, however, the molecular underpinnings of metamorphosis across diverse species are not well understood.

Exceptional endemicity of Aotearoa New Zealand biota shows how taxa dispersal traits, but not phylogeny, correlate with global species richness. [PDF]

J R Soc N Z
ABSTRACT Species’ with more limited dispersal and consequently less gene flow are more likely to form new spatially segregated species and thus contribute disproportionally to endemic biota and global species richness. Aotearoa New Zealand has exceptional endemicity, with 52% of its 54,000 named species endemic, including 32%, 39% and 68% for ...

Neritic Jellyfishes (Cnidaria: Cubozoa and Scyphozoa) from the coast of Rio Grande do Norte state, northeast of Brazil [PDF]

Check List, 2009
For the entire Brazilian coast, there are 22 published records of scyphozoans. On the other hand, only 35 species ofcubozoans were described worldwide, four of them reported for the Brazilian coast.

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 ...

Microanatomy of the cubopolyp,Tripedalia cystophora (Class Cubozoa) [PDF]

Helgoländer Wissenschaftliche Meeresuntersuchungen, 1978
The microanatomy of a cubopolyp (polypoid stage of Cubomedusae) is described for the first time. The 0.5–1.0 mm long polyp ofTripedialia cystophora has an oral cone with special lip cells at the mouth. Next is a baggy calyx occasionally followed by a slender stalk. The basal region is surrounded by a thin periderm.

Phylogenomic Analyses Support Traditional Relationships within Cnidaria. [PDF]

PLoS ONE, 2015
Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well understood because phylogenetic relationships among major ...

Elucidation of Medusozoan (Jellyfish) Venom Constituent Activities Using Constellation Pharmacology

Toxins
Within the phylum Cnidaria, sea anemones (class Anthozoa) express a rich diversity of ion-channel peptide modulators with biomedical applications, but corollary discoveries from jellyfish (subphylum Medusozoa) are lacking.
