With more than a quarter of elasmobranchs considered endangered and another 47 per cent lacking basic biological data, there has never been a more crucial time for shark and ray scientists to work collaboratively and efficiently to understand the biology, ecology and physiology of elasmobranchs. Although opportunistic tissue collection occurs often in the field, in many cases not all potential samples are collected, samples are disposed of due to a lack of institutional storage, or they are left in freezers for potential future projects, which may not materialize. Additionally, sourcing samples for research projects remains challenging without broad global connections. Here, we propose an online database (Shark Share Global) to help overcome sampling inefficiencies and provide a user-friendly platform for sharing elasmobranch tissues. By creating a virtual global tissue bank, Shark Share Global is able to facilitate collaborative efforts, increasing multidisciplinary research without drastically increasing project costs. Here, we will introduce the database, its functionality and expected outcomes for the greater elasmobranch research community.
