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.

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...

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...
En la naturaleza existen tesoros muy antiguos, casi como la vida misma. Uno de ellos data de hace aproximadamente 600 millones de años y yace oculto en todos los mares. Este tesoro recibe el nombre de medusozoos. Te invitamos a conocer quienes lo conforman y a sus principales investigadores en el Pacífico mexicano. En este texto también conocerás p...
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...
Morphological characters of hydromedusae and their description in Spanish and English, besides structure synonyms, are included. For the compilation of the terms with their synonyms and definitions, a search and consultation were carried out in scientific articles, online databases, dictionaries, and specialized books on hydromedusae, and the autho...

The Mexican Pacific has been the focus of several research expeditions, with 90 species of hydromedusae and more than 200 species of hydroids recorded for the region. However, only a few of these reports include taxonomic descriptions, hindering inferences of the phylogenetic relationships, species boundaries, and diversity of Hydrozoa in Mexican w...
Los sifonóforos conforman uno de los grupos más interesantes de todo el reino animal. Los sifonóforos son animales carnívoros, se presentan en una amplia variedad de formas y tamaños, y pueden producir bioluminiscencia. Se conocen 190 especies de sifonóforos, de las cuales 106 se encuentran en aguas mexicanas. A diferencia de otros cnidarios, los s...
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...
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)...
Values obtained from LMR and HMR measured at TIMR min and TIMR max conditions for 5 min for Centropomus undecimalis (Snook), Ocyurus chrysurus (Yellow tail) and Amphyprion ocellaris (clownfish).
Centropomus undecimalis in the acrylic swim-flume respirometry chamber maintained at a water speed of 2 cm s−1.
Centropomus undecimalis in the closed respirometry chamber after chase protocol.
Ocyurus chrysurus juvenile during TIMR max measurement in a closed circulation setting.
Critical thermal maxima and minima of several species of mollusc (m), crustacean (c), and fish (f) groups, with respective geographic coordinates and habitat (sw= seawater; fw= freshwater; and t= terrestrial).
Effect of acclimation temperature in Q10 values obtained using data of oxygen consumption (Low and high metabolic rates, i.e., LMR and HMR) of the three fish species exposed at the temperatures used to induce metabolic rates (TIMR min and max, respectively) at each acclimation temperature. Note that data of clownfish where placed in the secondary a...
The chase protocol applied to Centropomus undecimalis.
Ocyurus chrysurus juvenile during TIMR min measurement in a closed circulation setting.
Considering that swim-flume or chasing methods fail in the estimation of maximum metabolic rate and in the estimation of Aerobic Scope (AS) of sedentary or sluggish aquatic ectotherms, we propose a novel conceptual approach in which high metabolic rates can be obtained through stimulation of organism metabolic activity using high and low non-lethal...
En el presente estudio se evaluó el efecto que tiene en el crecimiento y en el
acondicionamiento reproductivo la inclusión de ácidos grasos poliinsaturados a la
dieta de Octopus maya en condiciones de cultivo en colectivo e individual. Para
conocer la forma en que las condiciones de cultivo y la dieta alta en ácidos grados
poliinsaturados modulan e...
