This study reports on 25 species of hydroids occurring in the collections gathered during KANACONO and KANADEEP expeditions carried out in the SE of New Caledonia in 2016, and off the western coast of the island in 2017, respectively. Of these, 19 have not been dealt with in earlier reports on these collections. Two new genera and four new species are described, viz, Actinopluma mirifica Galea gen. et sp. nov., provisionally assigned to the family Kirchenpaueriidae Stechow, 1921, Schizoplumularia helicoidalis sp. nov., belonging to the Plumulariidae McCrady, 1859, and Corhiza patula Galea sp. nov. and Thamnopteros uniserius Galea gen. et sp. nov., both placed in the family Halopterididae Millard, 1962. The gonotheca and the medusoid gonophore of Plumularia contraria Ansín Agís et al., 2014 are described for the first time, allowing a genus transfer to Dentitheca Stechow, 1919, as D. contraria comb. nov. Plumularia conjuncta Billard, 1913, known earlier from a minute portion of colony, is redescribed based on a complete, though infertile, specimen. Similarly, complete specimens corresponding to the hydroid previously referred to as Antennella megatheca Ansín Agís et al., 2009 are documented, allowing a provisional reallocation to Corhiza Millard, 1962 and a description of its so far unknown gonothecae. Fertile material assignable to the poorly-known Monostaechas fisheri Nutting, 1905 allows the recognition of this hydroid as a valid species, distinct from M. quadridens (McCrady, 1859). Most taxa are illustrated to validate the reliability of their identifications. Finally, phylogenetic reconstructions of the families Aglaopheniidae, Plumulariidae, and Halopterididae, based on the 16S rRNA, allowed a first genetic characterization of some of the species dealt with in this work.

“…This study recorded the presence of O. dichotoma , which has been considered an invasive species in Mexico ( González et al, 2014 ; Global Biodiversity Information Facility (GBIF), 2019 ) and a common epibiont hydroid of pelagic and benthic Sargassum (six species) ( Nishihira, 1965 ; Calder, 1995 ; Morri & Bianchi, 1999 ; Oliveira, Marques & Migotto, 2006 ; Cunha & Jacobucci, 2010 ). We also recorded thriving colonies of A. latecarinata , which it is an aglaophenid no venomous to humans, contrary to other members of the family Aglaopheniidae (e.g., A. cupressina, A. pluma, M. philippina ) ( Svoboda & Cornelius, 1991 ; Tang, 1991 , as cited in Tseng et al, 2014 ; Rifkin, Williamson & Fenner, 1996 ; Santhanam, 2020 ).…”

Massive accumulations of pelagic species of Sargassum have generated recent social, economic and ecological problems along Caribbean shores. In the Mexican Caribbean, these events have prompted the study of diverse biological and ecological aspects of these macroalgae. However, studies on their associated biota, including Hydrozoa, remain scarce. This research provides important species observations in an area where data is lacking. The occurrence and percent cover of hydroids on Sargassum thalli collected on the beach at Puerto Morelos, Quintana Roo, Mexico from April 2018 to March 2019 was studied. Three pelagic species and morphotypes of Sargassum from this area were analyzed: Sargassum fluitans III, S. natans I and S. natans VIII, as well as a benthic species, S. polyceratium var. ovatum. A total of 14 taxa of hydroids, belonging to the superorders “Anthoathecata” and Leptothecata, were identified. In our study, more hydroid taxa were observed on axes of the different species of Sargassum than on leaves or aerocysts. In general, the greatest species richness of hydroids was observed from February to April. Results show that live hydrozoans attached to pelagic Sargassum are transported into the area. This should be considered in future management measures that address the recurring coastal abundance of Sargassum and its associated biota in the Caribbean region.

“…In order to resolve this problem, marine inhabitants become the highly recommends solution because until recently only very limited exploration have been done in term of its active chemical entities. Hydroids, one type of marine invertebrates, found to be fascinate and unique inhabitant which grown independently or in a symbiotic ways with other marine organisms like sponges, corals, molluscs, micro and macro algae, and even micro-organisms to produce some interesting compounds 2 . As a lower rank animal, without physical defence system, hydroid using the chemical system of protection by directly synthesized chemical toxins, or in a symbiotic way with other marine inhabitants, like bacteria, who can synthesise those chemical toxins and will be co-jointly used in order to protect both against predators or competitors 3 .…”

Hydroids, one type of marine invertebrates, known to produce numbers of interesting metabolites with a various practical application, such as antimicrobial, anticancer, and anti-inflammation. Aims of this investigation are to isolate, purify, and determine the structure of molecules from dichloromethane fraction of hydroid, Aglaophenia cupressina Lamouroux, and further test its antibacterial activities against Staphylococcus aureus and Escherichia coli. Unexpectedly, β-sitosterol acetate was isolated with an amount of 9 mg and m.p 134-135 o C. A further testing against Staphylococcus aureus and Escherichia coli also gave an inhibition zone diameter of 11.5 and 8.15 respectively which considerably good for antibacterial agent

Hydroids (Cnidaria, Hydrozoa) from marine environments in Taiwan

Abstract: Background: Hydroids were identified from extensive surveys of benthos, and especially from worm tubes, in the Danshuei River estuary (DRE), in the northeast Taiwan Strait (NETS), and on a reef in Nanwan Bay (NWB), Taiwan.
