“…This result revealed that the NADH complex genes of Tonnoidean are experiencing a more relaxed purifying selection compared with the COX genes which appear more conservative. Similar trends have also been detected in other gastropod taxa [51,52].

The Tonnoidea Suter, 1913 (1825) is a moderately diverse group of large predatory gastropods, the systematics of which remain unclear. In the present study, the complete mitochondrial genomes of nine Tonnoidean species were sequenced. All newly sequenced mitogenomes contain 13 protein-coding genes (PCGs), 22 transfer RNA genes and two ribosomal RNA genes, showing similar patterns in genome size, gene order and nucleotide composition. The ratio of nonsynonymous to synonymous of PCGs indicated that NADH complex genes of Tonnoideans were experiencing a more relaxed purifying selection compared with the COX genes. The reconstructed phylogeny based on the combined amino acid sequences of 13 protein-coding genes and the nucleotide sequences of two rRNA genes supported that Ficidae Meek, 1864 (1840) is a sister to Tonnoidea. The monophylies of all Tonnoidean families were recovered and the internal phylogenetic relationships were consistent with the current classification. The phylogeny also revealed that Tutufa rebuta (Linnaeus, 1758) is composed of at least two different species, indicating that the species diversity within Bursidae Thiele, 1925 might be underestimated. The present study contributes to the understanding of the Tonnoidean systematics, and it could provide important information for the revision of Tonnoidean systematics in the future.

Coral reef ecosystems are home to many organisms, including bivalves, gastropods, crinoids, and demersal fish, making biodiversity assessment crucial for effective conservation and management. This study aims to: i) apply DNA barcoding to identify coral and megabenthic species in coral reef ecosystems, and ii) construct phylogenetic tree to trace their evolutionary relationships. Using quantitative descriptive methods and purposive sampling, specimens were collected in July 2023. The study yielded one coral (R2), one hydrozoan (R3), and one gastropod (GP-1) sample were successfully barcoded. DNA barcoding through Cytochrome Oxydase I (COI) gene amplification revealed that sample R2 had a 98.70% similarity with Acropora hyacinthus, sample R3 had a 98.92% similarity with Zanclea galli, and sample GP-1 had a 91.19% similarity with Erronea errones. Phylogenetic analysis positioned R2 in the same clade as Acropora hyacinthus and related genera such as Montipora, Astreopora, and Alveopora, within the Acroporidae family. R3 clustered with Zanclea galli in the hydrozoan group, alongside Z. sesillis, Z. implexa, and Z. sango. GP-1 grouped with Erronea errones in the gastropod genus Erronea, showing relationships with other genera such as Blasicrura, Cribrarula, Bistolida, and Eclogavena within the subfamily Erroneinae. Species inventories like this are essential for the conservation and management of coral reefs, which are key habitats for fish and other marine life.

Cowries (Cypraeidae) are popular among shell collectors because of their beauty and relative availability. Some species of cowry have high collection values among shell markets, however this has led to an increase number of species and unnecessary proliferation of taxonomic names with little information on their morphology. Thus, this study was conducted to describe morphological variations among cowry shells obtained along Sindangan Bay, Philippines. The shell morphological attributes (e.g. shell shape, color, bands, banding pattern), morphometric characters (e.g. shell length, width, height, number of teeth, etc.), and shape were characterized using the relative warp scores generated from the outline and landmark-based geometric morphometric analysis (GM) and correlation analysis based on distances (CORIANDIS). Sixteen (16) morphological and ten (10) meristic characters of 113 samples from the seven Cypraeidae species were examined and analyzed. The variations on color, banding pattern, lateral margins, dorsal/transverse line, spire, teeth, size and shape of the shell were mainly observed. Relative warp analysis showed significant shell shape variation among Cypraeidae species. Correlation analysis based on distances showed morphological, size, and shape differences among Cypraeidae species. As revealed in correlation analysis, the observed variation in size was significantly correlated with shape. The observed differences could be due to many factors including genetic, biotic and abiotic factors; developmental processes and physiology in responses of the organisms to a unique environment. Thus, geometric morphometrics and CORIANDIS helped us understand the nature of diversity in the family Cypraeidae species. Further studies on environmental heterogeneity, species position within the population’s distribution, and the genetic basis of the observed phenotypic diversity are necessary. Such emphasis can lead to additional information in the systematic studies on species of family Cypraeidae.
