Rhizostomeae research based on morphological approaches was reinforced and diversified by new techniques after the 1970s, including developing methodologies for phylogenetic analysis, the rise of the polymerase chain reaction, and the emergence of different sequencing technologies. Here, we summarize the contribution of morphological and molecular data to the study of the classification and phylogenetic relationships of Rhizostomeae in addition to the use of molecular data in studies at the population, species, and supraspecific levels. Throughout the history of the study of the Rhizostomeae systematics, morphological data have been neglected when it comes to phylogenetic inferences, which is reflected in the lack of a phylogenetic analysis of the taxa within Rhizostomeae based on phenotypic characters of the adult medusa.

Previous findings have confirmed the jellyfish's ability to synthesize large ATP amounts, mainly produced by mitochondria, in response to environmental challenges. This study characterized the respiratory chain from the mitochondria of the jellyfish Stomolophus sp2 (previously misidentified as Stomolophus meleagris).

- * This study evaluated five different RNA extraction methods on WSSV-infected shrimp, finding that the TRIzol method yielded the highest total RNA, while the Zymo Direct-zol RNA MiniPrep kit enabled the earliest detection of WSSV transcripts.
- * The results indicate that RNA isolation techniques significantly influence the detection of WSSV transcripts, which could enhance the accuracy of gene expression studies and improve diagnostic sensitivities.
Earth is inhabited by numerous adaptations of cellular forms shaped by the persistent scrutiny of natural selection. Thus, as natural selection has fixed beneficial adaptations of functional traits, cellular life has conquered almost all environmental niches on our planet. However, cellular life succumbs in number and genetic diversity to viruses.

- The jellyfish genus Stomolophus spp. in the Pacific Ocean, particularly Stomolophus sp. 2, has been under-researched despite its abundance and economic potential.
- This study aimed to detail the life cycle stages of Stomolophus sp. 2, revealing various reproductive forms and stress-induced changes, such as polyps converting to cysts.
- Due to significant differences in reproductive mechanisms and morphology compared to S. meleagris, the study proposes recognizing Stomolophus sp. 2 as a new species named Stomolophus yaquilli, honoring the local indigenous community.
