Ctenophores are one of the most conspicuous and frequent groups gelatinous zooplankton community, but their regional diversity in tropical subtropical latitudes remains largely unknown. We provide an overview update current knowledge Mexican seas, including ocean coastal-neritic environments Gulf Mexico, Caribbean Sea, Pacific Ocean. Ctenophore records were reviewed based on available scientifi...

Abstract Domas coastal waters, located east of Banten Bay, have an enormous potential for fisheries resources closely related to the presence plankton in area. This study was carried out 6 months, from August 2021 January 2022, examine biodiversity and community structure zooplankton waters. Sampling monthly at six stations distributed areas sea. Data on were examined abundance, diversity, even...

SYNOPSIS. An in-depth understanding of the biology of animals will require the generation of genomics resources from organisms from all phyla in the metazoan phylogenetic tree. Such resources will ideally include complete genome sequences and comprehensive EST (expressed sequence tag) datasets for each species of interest. Of particular interest in this regard are animals in the early diverging...

The phylum Ctenophora (known as comb jellies) consists of gelatinous marine carnivores found from the surface to several thousand meters depth. Their morphology can be simple or complex, ranging from a sac-like shape with no tentacles to large lobed forms with sinuous "auricles," papillae, and two different kinds of tentacles. This diversity appears to reflect adaptations to many different diet...

This paper presents the first molecular phylogenetic analysis of the phylum Ctenophora, by use of 18S ribosomal RNA sequences from most of the major taxa. The ctenophores form a distinct monophyletic group that, based on this gene phylogeny, is most closely related to the cnidarians. Our results suggest that the ancestral ctenophore was tentaculate and cydippid-like and that the presently recog...
