Rostral anomaly in a juvenile Spiny Butterfly Ray Gymnura altavela (Linnaeus, 1758) (Elasmobranchii: Myliobatiformes: Gymnuridae) from the Canary Islands
TLDR
The present communication documents the first observation of a morphologic anomaly in a juvenile Spiny Butterfly Ray Gymnura altavela, and reinforces the hypothesis of a congenital disorder for this type of malformation within the genus. Expand
Age and growth assessment of western North Atlantic spiny butterfly ray Gymnura altavela (L. 1758) using computed tomography of vertebral centra
TLDR
Results indicated sexually dimorphic growth patterns, with males growing faster and reaching asymptotic size at earlier ages than females, and suggest that G. altavela grows at a similar rate as some teleosts and batoids, and relatively fast among chondrichthyans. Expand
Diet and reproduction in the Australian butterfly ray Gymnura australis from northern and north-eastern Australia.
TLDR
The diet of Gymnura australis was dominated by teleosts (99.8% index of relative importance) and the species had a single functional ovary and two functional uteri. Expand

Distribution and Abundance of Coastal Elasmobranchs in Tenerife (Canary Islands, NE Atlantic Ocean) with Emphasis on the Bull Ray, Aetomylaeus bovinus
The current status of the elasmobranchs’ populations and distribution in the Canary Islands is uncertain. Here we investigate the abundance and distribution patterns of coastal elasmobranchs ofExpand
Reproductive biology and diet of the longtail butterfly ray Gymnura poecilura (Shaw, 1804) along western Bay of Bengal
TLDR
Year-round reproduction was indicated, due to the presence of mature males and gravid females throughout the year, neonates in multiple months and large variations in embryo size within months. Expand
“Urbanite” rays and sharks: Presence, habitat use and population structure in an urban semi-enclosed lagoon
Abstract There is a vital necessity to provide more biological data on rays and sharks to promote efficient conservation. In this study, we assembled a database of weekly sightings to describeExpand
REPORT OF INJURIES IN BATOIDS CAUGHT IN SMALL-SCALE FISHERIES: IMPLICATIONS FOR MANAGEMENT PLANS
Despite of the ecological importance of several batoids caught as bycatch, little attention is given to the individual resilience in risk assessments. The report of physical condition is imperativeExpand
Reproductive characteristics and reproductive tract anatomy of the California butterfly ray Gymnura marmorata (Myliobatiformes: Gymnuridae).
TLDR
The California butterfly ray Gymnura marmorata is frequently caught by artisanal fisheries in north-western Mexico and its reproductive characteristics are estimated and the micro and macroscopic reproductive structures of female and male G. marMorata are described. Expand
