How many #sharks should there be on a coral #reef? Our new publication in Science tackles this question using thousands of fossil shark dermal denticles—tiny, tooth-like scales that are shed and preserve in sediments—from Panama's two oceans. Check it out here: doi.org/10.1126/scie...

By analyzing thousands of otoliths preserved in sediments, we found that fish were larger on average at death on reefs in Pacific Panama, compared to those along the Caribbean coast, and that this difference has widened over time.

New paper out today! "Fossil otolith assemblages reveal millennial-scale changes in reef fish biomass and trophic structure across the Isthmus of Panama" 🔓https://doi.org/10.1098/rstb.2024.0419 We used fossil fish otoliths to reconstruct community structure and energetics over millennia.

A juvenile bull shakr found in Hong Kong ! sc.mp/s2ygf?utm_so...

Bull shark found stranded in Hong Kong mudflats returned to sea by residents
Despite being caught in Pak Nai fishing nets, scientist says presence of juvenile shark suggests city’s ‘abused’ marine ecosystem is recovering.
