Evidence of dystocia in an oviparous shark.

Dystocia, or obstructed labor, is a well‐documented phenomenon in various captive vertebrates, including fish. However, despite the documentation of dystocia in several viviparous (live‐bearing) Chondrichthyan species (i.e., sharks, rays, skates, and chimaeras), there are no reports to date of dystocia in any oviparous (egg‐laying) species. Here we present a case of a captive female epaulette shark (Hemiscyllium ocellatum) that demonstrated symptoms of dystocia in a research‐related captive breeding programme. This communication serves as documentation that dystocia can occur in oviparous Chondrichthyans, and this information can help inform researchers and veterinary practitioners for improved care.
