Preliminary Investigation of the Ocular Macroscopic Structure of a Bowmouth Guitarfish (Rhina ancylostoma Bloch & Schneider 1801)
Bowmouth guitarfish is one of the rare and endangered aquatic species [1] in class Chondrichthyes, subclass Elasmobranchii, which includes sharks and rays (Batoidea), order Rajiformes, and the only species in the family Rhinidae and genus Rhina [2]. Its habitats include the Indian and the Pacific oceans and have been reported from Australia to the south of the Arabian Peninsula. An adult guitar...
متن کاملCorrection: Molecular and Morphological Analyses Reveal Phylogenetic Relationships of Stingrays Focusing on the Family Dasyatidae (Myliobatiformes)
There are errors in identification steps 1a and 1b in the “Key to the families of Order Myliobatiformes” subsection of the Results. The correct step 1a is: Disc broad and laterally expanded with wing like pectoral fin, disc width more than 1.3 times disc length (Fig 5A & 5B). . .. . .2. The correct step 1b is: Disc not greatly expanded, diamond or round shaped, disc width less than 1.3 times di...
متن کاملMolecular and Morphological Analyses Reveal Phylogenetic Relationships of Stingrays Focusing on the Family Dasyatidae (Myliobatiformes)
Elucidating the phylogenetic relationships of the current but problematic Dasyatidae (Order Myliobatiformes) was the first priority of the current study. Here, we studied three molecular gene markers of 43 species (COI gene), 33 species (ND2 gene) and 34 species (RAG1 gene) of stingrays to draft out the phylogenetic tree of the order. Nine character states were identified and used to confirm th...
متن کاملSpecies boundaries in the Himantura uarnak species complex (Myliobatiformes: Dasyatidae).
Samples of the 'Himantura uarnak' species complex (H. leoparda, H. uarnak, H. undulata under their current definitions), mostly from the Coral Triangle, were analyzed using nuclear markers and mitochondrial DNA sequences. Genotypes at five intron loci showed four reproductively isolated clusters of individuals. The COI sequences showed four major mitochondrial lineages, each diagnostic of a clu...
متن کاملCytogenetic studies in the redtail catfish, Phractocephalus hemioliopterus (Bloch & Schneider, 1801) (Siluriformes, Pimelodidae) a giant fish from Amazon basin
The objective of this study was to cytogenetically analyze Phractocephalus hemioliopterus comparing the findings with other data to infer relationships among Pimelodidae species. The results revealed a diploid number of 2n = 56 and the karyotype composed of 16 metacentric, 20 submetacentric, 6 subtelocentric and 14 acrocentric chromosomes (FN = 98). The Ag-NORs, 18S rDNA and CMA3 signals were c...
