Abstract

Many biological aspects of deep-water sharks are poorly known due to their rarity and difficulties in conducting detailed research on them. The angular roughshark (Oxynotus centrina) is a rare species, critically endangered in the Mediterranean Sea, of which records are scarce across this region. Here we present a record of a female neonate O. centrina from the south-eastern Adriatic Sea, caught by a Montenegrin commercial trawler. Scientific observers were present on-board and collected the specimen, which was subsequently analysed in the laboratory. The specimen was 225 mm long (TL), weighed 59.6 g and had an unhealed umbilical scar. To date, records of this species in the Adriatic Sea have comprised of both adult and older juvenile individuals, but no records of neonates were found in the published literature. In this work, the basic biological observations of the specimen are reported.
亚得里亚海东部首次发现新生海生猪Oxynotus中心
由于它们的稀有和对它们进行详细研究的困难,人们对深水鲨鱼的许多生物学方面知之甚少。角粗鲨(Oxynotus centrina)是一种稀有物种,在地中海极度濒危,其记录在整个地区都很稀少。在这里,我们介绍了一条来自亚得里亚海东南部的雌性新生O. centrina,被黑山商业拖网渔船捕获。科学观察员在船上收集了标本,随后在实验室进行了分析。标本长225毫米(TL),重59.6克,有一个未愈合的脐带疤痕。迄今为止,亚得里亚海的这一物种的记录包括成年和年长的幼崽,但在已发表的文献中没有发现新生儿的记录。在这项工作中,报告了标本的基本生物学观察结果。
