Egg capsules of deep-sea catsharks from Eastern North Atlantic, with first descriptions of the capsule of Galeus murinus and Apristurus aphyodes (Chondrichthyes: Scyliorhinidae)
Egg capsules of four species of the deepwater catshark genera Galeus and Apristurus are described and compared. The egg capsules of G. murinus and A. aphyodes are firstly described from 4 and 9 capsules respectively, collected in the mother's oviducts. Unlike numerous species of the family, the...

| description | Egg capsules of four species of the deepwater catshark genera Galeus and Apristurus are described and compared. The egg capsules of G. murinus and A. aphyodes are firstly described from 4 and 9 capsules respectively, collected in the mother's oviducts. Unlike numerous species of the family, their egg capsules do not have prolonged tendrils. The smallest gravid females of G. murinus and A. aphyodes measure 460 and 490 mm respectively. Their oviparous mode of reproduction was confirmed. There is only one egg capsule per oviduct for both species, indicating they are single oviparous species. Comments are made on the oviparity of the catsharks of these genera.Original Abstract: Les capsules ovigeres de quatre especes de Scyliorhinidae de profondeur des genres Galeus et Apristurus sont decrites et comparees. Les capsules ovigeres de G. murinus et A. aphyodes sont decrites pour la premiere fois, respectivement a partir de 4 et 9 capsules prelevees dans les oviductes des meres. Contrairement a de nombreuses especes de la famille, leurs capsules ovigeres ne sont pas prolongees par des vrilles. Les plus petites femelles gravides de G. murinus et d'A. aphyodes mesurent respectivement 460 et 490 mm. L'oviparite de ces roussettes a ete confirmee. Il n'y a qu'une seule capsule ovigere par oviducte pour chacune de ces especes, ce qui indique une reproduction de type simple oviparite. L'oviparite des roussettes appartenant a ces genres est commentee. |
