Fantastic Sharkipedia workshop today at #SI2026 Lots of great discussions and ideas about how we can improve, especially for education and outreach. Thanks to all who attended and to @sharks-int.bsky.social for hosting us! #SharkConservationFund @saveourseas.bsky.social

Depending on the mining type there are varying degrees of depth overlap between impacts and species depth ranges. We highlight four recommendations including limiting discharge plumes to below 2,000 meters to limit overlap with sharks and rays. @seaprinceaaron.bsky.social @nickdulvy.bsky.social

New paper led by @seaprinceaaron.bsky.social in @currentbiology.bsky.social looking at the threats deep sea mining poses for sharks, rays, and chimaeras. We found 30 species are threatened via various pathways including collector impact and plumes at depth and pelagic discharge plumes.

Figure 1: highlighting various pathways through which mining can impact sharks, rays, and chimaeras including collector impact and plumes, and discharge plumes.

Figure 2: The diversity of sharks, rays, and chimaeras impacted by deep sea mining operations. Nearly 2/3 of these species are already at an elevated risk of extinction.

Despite lots of work already being done, these aspects (movement, trophic interactions, and demographics) are often studied in isolation. But they are each a piece of the puzzle. Often times there are taxonomic biases in research. This doesn't even cover the rays! @natklinard.bsky.social

Sharks and rays can play many ecological roles (predators, prey, vectors, etc). The functional roles of individuals scale up depending on the ecological context. And there are many questions to consider @natklinard.bsky.social @johnwayne5.bsky.social
