Hox and ParaHox transcription factors are important for specifying cell fates along the primary body axes during the development of most animals. Within Cnidaria, much of the research on Hox/ParaHox genes has focused on Anthozoa (anemones and corals) and Hydrozoa (hydroids) and has concentrated on the evolution and function of cnidarian Hox genes i...
In this study we address the diversity of the scyphozoan jellyfish genus Nausithoe Kölliker, 1853 (Nausithoidae, Coronatae), questioning the feasibility of using some characters of the medusa stage to identify species and filling in gaps concerning species of the genus and their distributions. Like most scyphozoans, the vast majority of the 21 Naus...
The phylum Cnidaria consists of several morphologically diverse classes including Anthozoa, Cubozoa, Hydrozoa, Polypodiozoa, Scyphozoa, Staurozoa, and Myxozoa. Myxozoa comprises two subclasses of obligate parasites—Myxosporea and Malacosporea, which demonstrate various degrees of simplification. Myxosporea were previously reported to lack the major...
Transposable elements exert a significant influence on the structure and size of eukaryotic genomes. Representatives of Tc1/mariner superfamily of DNA transposons form a prevalent and highly variable group, which includes the relatively well studied TLE /DD34-38E, MLE /DD34D, maT /DD37D, Visitor /DD41D, Guest /DD39D, mosquito /DD37E and L18 /DD37E...
Mitogenomics has improved our understanding of medusozoan phylogeny. However, sequenced medusozoan mitogenomes remain scarce, and Medusozoa phylogeny studies often analyze mitogenomic sequences without incorporating mitogenome rearrangements. To better understand medusozoan evolution, we analyzed Medusozoa mitogenome phylogeny by sequencing and ass...

... A pesar del esfuerzo realizado por los trabajos de síntesis, el conocimiento de algunos taxones ha pasado desapercibido, como ciertos helmintos parásitos y picnogónidos, posiblemente derivado de referencias antiguas que no estaban disponibles. En una serie de trabajos más recientes y exhaustivos (ver: Bastida-Zavala & García-Madrigal, 2022a), se compiló y actualizó, hasta 2021, la información conocida sobre invertebrados marinos del PSM, con lo cual se incrementó significativamente la cantidad de especies conocidas de esponjas (Carballo & Vega, 2022), cnidarios (López-Pérez et al., 2022), anélidos , moluscos (Barrientos-Luján et al., 2022), picnogónidos (de León-Espinosa & de León-González, 2022), crustáceos (García-Madrigal et al., 2022), y equinodermos (Benítez-Villalobos et al., 2022). En algunos casos se incluyeron taxones recién estudiados en el PSM, como los platelmintos policládidos (Ramos-Sánchez & Bastida-Zavala, 2022) y sipúnculos (Silva-Morales, 2022). ...
The southern Mexican Pacific, which includes the states of Guerrero, Oaxaca, and Chiapas, has had a long, but intermittent, history of discoveries of new species of marine invertebrates, although this information was widely dispersed, and not previously compiled. From an exhaustive bibliographic review for the taxa, 283 species of marine invertebrates with type locality in this region are listed. Arthropods, annelids, mollusks and flatworms represent more than 77% of the described species. The species were described in a period of almost 190 years, although in the last two decades of the 21st century it increased substantially by more than 32%. Practically half of the species have been described by Mexican authors (46%) and the other half by foreigners (54%); Guerrero State is the one
that concentrates just over half of the species (53.4%). Among the national institutions, the Universidad Nacional Autónoma de México houses the authors who have described the most species (48.8%), followed by the Universidad del Mar (32.6%). Two Mexican and two foreign authors have described 31.4% of the species in the region. Emphasis is placed on the need to increase exploration efforts in Chiapas State, as well as to promote regional workshops on several marine invertebrate taxa, to stimulate the training of new specialists.
