I lift the lid on the oceans & census the life hidden beneath by combining Darwin’s toolbox–of natural history field guides, thermometer, microscope, and dissection kit–with big-data approaches @earth2ocean.bsky.social

Goby gummies: the fish ‘lolly’ that provides a window to study predation underwater

Have you checked out our free Guide to Graduate Studies recently? It's a great starting point for anyone considering a graduate degree related to #ornithology.

The Moth Cup is on! Six moths from six continents, head to head, and it’s up to you to crown a champion for the year. Voting starts tomorrow in our Instagram stories, one match per day. And remember, the moth that loses by the smallest margin will have a second chance in the next round!
We also built a free Shark & Ray MPA Explorer so researchers, managers, and conservationists can explore species-level MPA coverage for all 1,158 species. If you're interested in sharks and rays, take a look! tinyurl.com/SharkRayMPAExplorer @sfubiosciences.bsky.social @society4conbio.bsky.social
We suggest three ways forward: • Monitor biodiversity outcomes alongside spatial targets like 30×30. • Require reporting of take status to the WDPA. • Incorporate biodiversity explicitly when designing MPAs. @sfugradstudies.bsky.social
Another major finding: Much of the reported MPA coverage comes from sites where take regulations aren't reported to the World Database on Protected Areas. Only about 34% of countries report take status for any of their MPAs, making it difficult to evaluate how much effective protection exists.
Some of our key findings: • Only 6 threatened sharks and rays have more than 10% of their range protected by no-take MPAs. • Only 24% of threatened sharks and 18% of threatened rays have over 1% of their species range covered by no-take MPAs @sfubiosciences.bsky.social @earth2ocean.bsky.social
Marine Protected Areas (MPAs) are one of the main ways we protect the ocean, but an important question often goes unasked: How does global MPA coverage actually relate to species range coverage? We quantified MPA coverage across the national-water ranges of 1,158 species. @sfuscience.bsky.social
Most shark and ray species have <1% of their range covered by no-take MPAs. New open access in @consletters.bsky.social: Sharks, Rays, & MPAs: a global assessment of MPA coverage in national waters across species ranges tinyurl.com/SharkRayMPA @nickdulvy.bsky.social @jaymatsushiba.bsky.social

#JMIH26 #AES26 Shelby Pawlikowski Compared genetics of rays @ popular Grand Cayman ecotourism site "Stingray City" w/ other locations. Feeding causes aggregation, but very little inbreeding
Carylanne Joubert Maier@carylanneejmaier.bsky.social · 4w agoThankfully, inbreeding seems low at the site based on current data, which was comparable to other non-fed populations. This also contributed to a good genomic diversity that is similar to other aggregations.

Two years ago, I covered the story of Critically Endangered sawfish mysteriously swimming around in circles until they die. Today at the American Elasmobranch Society meeting, there’s a whole symposium about this topic. www.southernfriedscience.com/critically-e...
Critically Endangered sawfish are spinning in circles until they die. What the heck is going on?
An epidemic of spinning disease is killing these Critically Endangered animals in a horrifying way. I spoke to experts to help understand what’s going on and what’s being done to help. …

— for bringing together this important reflection on three decades of Red List work. And a huge thank you to the previous Red List Authority Coordinators and the thousands of experts, assessors, coordinators, and partners who have contributed to this work over the past three decades.

@nickdulvy.bsky.social at #SI2026 We don’t just need more biodiversity data to save the ocean, we need to correct for colonialism and racism in our global power structures. Most sustainable fishing is in wealthy countries, most fishing is in South America or Asia.

Come and see our poster at #SI2026 on distribution and habitat associations of threatened elasmobranchs in Scotland. Hall A over the next couple of days. See you there! 🦈
I’m attending #si2026 this week in Colombo, Sri Lanka. Five whole days where I can geek out about rays… it’s an absolute dream.
Martins at #SI2026 Sharks and rays are eaten by coastal communities worldwide and play key roles in food security, which must be considered in shark conservation discussions. Her team analyzed the nutritional value of shark and ray meat.
Hearn at #SI2026 A seamount called Paramount near the Galapagos is critically habitat for scalloped hammerhead sharks, but lies just outside the borders of a marine protected area. It’s now a recognized Important Shark and Ray Area.
Cardeñosa at #SI2026 Since getting CITES protections, shark fin imports from threatened species have decreased. But trade is still happening, they’re finding fins in the market that aren’t being reported- Shark fins from some species are found 70 times more frequently than is being reported.
Shea at #SI2026 Since the government stopped serving luxury items at government functions, there’s been a big decrease in shark fin soup consumption. The Hong Kong public also cites rising environmental concerns, showing success of environmental advocacy.

@sharkcolin.bsky.social at #SI2026 @cms.int is a major international conservation treaty focusing on migratory species. Several shark species meet the “migratory” definition, 39 species currently listed but ~150 species qualify.
Yamaguchi at #SI2026 In Japan, sharks have been killed for centuries to stop them from eating fish that fishermen wanted. Scalloped hammerhead sharks are of serious conservation concern, and her team has documented some critical habitat in Ariake Bay, Japan
