The cubozoans, a small group of medusozoans with 50 nominal species, have been under research, leading to uncertainty about the validity of some specimens. This study aims to confirm the species found in the western region of the Caribbean Sea. We conducted a review, utilizing specimens from samples collected, zooplankton collection, and collected...
The scaleworm Pelogenia fimbriata (Hartman, 1939) collected from Secas Islands, Panama, during the Allan Hancock Pacific Expedition in 1916, was not only recognized as an undescribed species at the time of discovery but has also revealed a new finding almost nine decades after its description. A paratype of P. fimbriata was examined in the Natural...
The taxonomic complexity of the families Clathrozoidae and Clathrozoellidae, rooted in early 20th-century hydroid descriptions, highlights the need for comprehensive and detailed morphological analyses. This study aimed to elucidate the histology of the polypoid stage of Clathrozoella medeae Peña Cantero, Vervoort & Watson, 2003, with a particular...
This study provides a detailed analysis of the community of hydrozoan epibionts of Acanthophora spicifera in La Paz Bay, Baja California Sur. The investigation was carried out in two season periods, corresponding to the warm and cold seasons on the pier of the Autonomous University of Baja California Sur (UABCS) Pichilingue research station. The pe...
Background
The red macroalga Gracilaria parvispora is an introduced species in the Mexican Pacific. To date, there are no published studies on its sessile epibionts, including the hydrozoans and bryozoans, which are the dominant epibionts on macrophytes and of significant biological and economic interest.
New information
This study provides insigh...
Acanthophora spicifera, a red alga considered an alien species, was discovered for the first time on the Pacific coast of Mexico in 2006 from a locality inside La Paz Bay, Gulf of California. Since then, more records have shown its presence, 17 localities having been added up to 2015. A two-year field study (2020-2022) visiting 31 sites along the c...
Access to digital technology and software allows the production of a significant amount of biodiversity data, including citizens' species records, combined with field monitoring and standardized surveys, which are valuable to biological sciences; these data can help to know the distribution of organisms like medusozoans. We compiled records of the...
Los hidroides son animales acuáticos pequeños que pertenecen al filo Cnidaria, grupo taxonómico dentro del cual encontramos corales, anémonas, medusas y pólipos. Pueden vivir sobre diversos sustratos, incluyendo otros organismos vivos, así como materiales naturales y artificiales. Los hidroides logran fijarse a los sustratos por medio de una “raíz”...
Medusozoans are diverse in species number (4100) and life stages and are of ecological and social importance worldwide. However, studies of medusozoans in the Mexican Pacific (MP) are limited and scattered. Given that its maritime (2,320,380 km2) and coastal (7828 km) regions are the most extensive in Mexico, as well as its geomorphological and eco...
The brown alga Sargassum provides a natural substrate occupied by hydrozoans in shallow marine waters. A global count in 2007 listed 39 epibiotic species of Hydrozoa growing on Sargassum, but more studies have been published since, therefore, an update is timely, particularly due to the increased abundance of Sargassum in the Caribbean. This review...
Except for true jellyfish (Scyphozoa), other medusozoans are poorly known in the northern region of Veracruz, Mexico. The present study provides an updated list of the medusozoans, their taxonomical descriptions, species richness, and community structure seasonal variations in the Tampamachcoco lagoon and the neritic zone off the Tuxpan coast, Vera...
The cnidarians of the class Hydrozoa comprise 3720 species, are globally distributed, and can have complex life cycles. In the Espíritu Santo Archipelago (ESA), Mexico, hydrozoans are understudied, and, for this reason, the present work describes the taxocene of hydrozoans and their oceanographic preferences in the area. Hydrozoans were collected a...

Las medusas velero o velas de mar (Velella velella) son colonias de individuos (pólipos) con funciones especializadas, pero que funcionan de manera coordinada como un solo organismo. Presentan un ciclo de vida complejo, donde la fase de hidroide corresponde a la vela de mar que flota en la superficie del mar por medio de una cámara gaseosa con aspe...
Medusozoans are marine animals without backbones that live near the coasts, or in the depths of the oceans. Some of them are large, but others are even tinier than a seed. Medusozoans have been living on Earth for more than 600 million years. Their bodies are 95% water. Some medusozoans live attached to a surface, but others can swim freely. All me...

The seasonal variability of gelatinous zooplankton (siphonophores, medusae, and thaliaceans) abundance was investigated at Cabo Pulmo National Park (CPNP) from weekly zooplankton samples collected throughout 2014. The Gulf of California had prolonged warming during 2009-2019, with 2014 as the anomalously warm year preceding El Niño 2015-2016 compar...
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. T...

The skeleton plays a vital role in the survival of aquatic invertebrates by separating and protecting them from a changing environment. In most of these organisms, calcium carbonate (CaCO 3) is the principal constituent of the skeleton, while in others, only a part of the skeleton is calcified, or CaCO 3 is integrated into an organic skeleton struc...
Los medusozoos están divididos en cuatro subgrupos: Staurozoa (estauromedusas o medusas pedunculadas), Cubozoa (cubomedusas o medusas caja), Scyphozoa (escifomedusas y escifopólipos) e Hydrozoa (hidromedusas, hidropólipos y sifonóforos o cadenas de medusas). Los medusozoos son importantes desde el punto de vista evolutivo, ecológico, económico y so...
Staurozoa es una clase de cnidarios con cerca de 50 especies. Durante su
ciclo de vida, la estauromedusa conserva el pedúnculo del estauropólipo,
y es por lo tanto una medusa bentónica, frecuentemente adherida a algas
o rocas. La mayoría de sus especies están distribuidas en aguas frías,
polares y templadas, pero hay excepciones. En este artículo p...
La biogeografía de medusozoos se inicia efectivamente en el siglo XX. Esta disciplina integra la distribución de medusas y pólipos en espacio y tiempo, considerando
sus ciclos de vida y las múltiples estrategias reproductivas que poseen. Trabajos más
recientes en biogeografía, incluyen el componente genético de los organismos en
diferentes cuestion...
Tan fascinantes como el ser mitológico que les da nombre, las medusas resaltan por su “fantasmal” aspecto, sus versátiles formas de reproducción sexual y otras particularidades. Las hidromedusas son una clase importante de estos invertebrados, son microscópicas y algunas presentan un enorme potencial para la medicina (cáncer, alzhéimer y párkinson)...
We present phylogenetic analyses (parsimony, maximum likelihood and Bayesian inference) for 69 lineages of anthoathecate hydroids based on 18 morphological characters (12 proposed for the first time) plus mitochondrial (16S and COI) and nuclear (18S and 28S) molecular markers. This study aims to test the monophyly of the present
concept of the fami...
The exoskeleton is an important source of characters for the taxonomy of Hydroidolina. It originates as epidermal secretions and, among other functions, protects the coenosarc of the polypoid stage. However, comparative studies on the exoskeletal tissue origin, development, chemical, and structural characteristics, as well as its evolution and homo...
Here, we provide the first list of shallowwater hydroids for Alacranes Reef, Mexico, comprising 49 species in 33 genera. The most speciose superorder was Leptothecata (36 species), with three particularly diverse families: Clytiidae, Sertulariidae, and Plumulariidae. Three species were recorded for the first time in the Gulf of Mexico (GoM), and 13...
The benthic polyp phase of Medusozoa (Staurozoa, Cubozoa, Scyphozoa, and Hydrozoa) has endoskeletal or exoskeletal support systems, but their composition, development, and evolution is poorly known. In this contribution the variation in synthesis, structure, and function of the medusozoan exoskeleton was examined. In addition, an evolutionary hypot...
The family Bougainvilliidae comprises a group of anthoathecate hydrozoans that is biologically, ecologically and biogeographically poorly understood, and consequently, poorly taxonomically organized. Here, our goal is to synthesize knowledge of the family from an historical perspective, and to analyze their potential distribution based on their eco...
