Mesophotic coral ecosystems occur offshore and north of the Amazon River
Since the 1960s, it has been accepted that the distribution of reef-building corals off Brazil has its northernmost limit at the Manuel Luis Marine State Park (approximately 0°46´S, 44°15´W), about
Growth of the tropical zoanthid Palythoa caribaeorum (Cnidaria: Anthozoa) on reefs in northeastern Brazil.
TLDR
The present study corroborates the hypothesis that P. caribaeorum is important for coastal reef dynamics due to its fast and continuous growth and shows that the growth velocity may be an intrinsic characteristic of the species, with a strong genetic component.
Diversity and Distribution of Octocorallia
Octocorals are a group of striking presence in marine benthic communities. With approximately 3400 valid species the taxonomy of the group is still not resolved, mainly because of the variability of
Namuncurá Marine Protected Area: an oceanic hot spot of benthic biodiversity at Burdwood Bank, Argentina
TLDR
This contribution represents the most recent and complete checklist of benthic organisms (mainly mega and macrofauna) that summarized 240 taxa collected at three sites in the mentioned area and largely exceeds the values coming from other productive areas in Argentinean waters.
New records of octocorals (Cnidaria: Anthozoa) from the Brazilian coast
TLDR
7 new octocoral records are focused on, of which 5 are first records for South Atlantic waters: Leptogorgia stheno (Bayer, 1952), Muriceopsis bayeriana Sanchez, 2007, Muri - ceo psis flavida Bayer, 1961, Chironephthya sp.
Trophic ecology of the zoanthid Palythoa caribaeorum (Cnidaria: Anthozoa) on tropical reefs
TLDR
The results indicate the importance of this zoanthid in tropical reef ecosystems as a primary consumer that serves as an energy transfer link between the planktonic environment and the nektonic and benthic spheres.
The non-indigenous medusa Blackfordia virginica (Hydrozoa, Leptothecata) in tropical Brazil: 50 years of unnoticed presence
TLDR
The hypothesis that this non-indigenous species has been established in the region for several decades at least, and that it constitutes an exotic component of the community is supported.
The Transcriptome of the Zoanthid Protopalythoa variabilis (Cnidaria, Anthozoa) Predicts a Basal Repertoire of Toxin-like and Venom-Auxiliary Polypeptides
TLDR
The complex array of venom-related transcripts that are identified in P. variabilis provides novel insight into the toxin distribution among species and might contribute to the understanding of composition and evolution of venom polypeptides in toxiferous animals.
Brittle stars (Echinodermata: Ophiuroidea) associated with the octocoral Carijoa riisei (Cnidaria: Anthozoa) from the littoral of Pernambuco, Brazil
The present work records for the first time the association between ophiuroids and the octocoral Carijoa riisei. Carijoa riisei is a colonial octocoral very abundant in the littoral of Pernambuco
