- Reposted by David JacobyNew paper lead by @etspencer.bsky.social We use biologging to understand why great hammerheads may specialize on large prey like other sharks. If they hunt blacktips off south Florida then they probably only have to catch a shark once per month link.springer.com/journal/442
- Happy International Angel Shark Day, especially to all my wonderful colleagues @angelsharkproject.bsky.social These are a special, and heavily threatened set of species.

Latest satellite data shows a massive 22% drop in penguin numbers over the last 15 years in key regions. This is more than double the rate of loss that experts had expected... 🧵 1/8

- Herculean collation of >12K megafauna tracks, >100 species, reveals 75% overlap of critical habitats with shipping, fishing, pollution or warming. Protection targets not enough to safeguard megafauna. New paper in @science.org, led by @anammsequeira.bsky.social 👇 📸silvana-palacios,daniel-torobekov

- Reposted by David JacobyMeet the cookiecutter shark: 20 inches long, with the audacity to take perfect circles out of whales and submarines. Evolution didn’t give it size, so it gave it chaos. #marinelife
- Reposted by David JacobyStill hope for coral reefs. Using 28-years of data in Seychelles, we find reefs recovering 4-5 years faster from the 2016 bleaching event, than they did after 1998. Also, a reef that had regime-shifted to macroalgae for over 15 years, is recovering to coral. onlinelibrary.wiley.com/doi/10.1111/...

- Reposted by David JacobyNew #sharkscience Great to see new information about smalltooth sawfish in Cuba out today. Evidence that a local population may still exist, but numbers are likely low and action is required (and suggested in the paper). www.int-res.com/abstracts/es...
- Reposted by David JacobyFirst post on #Bluesky, thought I'd highlight some of our research this year with @netlab.bsky.social. Acoustic telemetry can be used to answer a whole variety of questions including; Residency in reef #sharks - doi.org/10.1038/s420...
- Beautifully described and illustrated research journey by the fantastic @ruchakarkarey.bsky.social discovering the square tailed grouper aggregation in the Lakshadweep. Let’s not overlook the powerful link of these natural occurrences with human communities. #RCUK2024
