Angular roughshark Oxynotus centrina (Squaliformes: Oxynotidae) in captivity feeding exclusively on elasmobranch eggs: an overlooked feeding niche or a matter of individual taste?
A specimen of angular roughshark Oxynotus centrina has been kept successfully in captivity for the first time. Over a period of 24 months, the specimen preyed exclusively on the contents of elasmobranch egg cases, suggesting a specialized trophic niche.
First confirmed record ofMolasp. A in the western Mediterranean Sea: morphological, molecular and parasitological findings
Recent molecular and morphological studies suggest the existence of at least three species of Mola (Mola spp. A, B and C). Currently, only Mola mola and Mola ramsayi are formally accepted and species A, B or C have not been assigned to these thus far. In this study, a large ocean sunfish in the western Mediterranean Sea was analysed molecularly and morphologically, identified as Mola sp. A and a detailed account of the specimen's parasite load is reported.
