New paper in Ecology & Evolution: analysed 187 species of rays & skates to explore patterns of sexual size dimorphism. Turns out SSD in rays doesn’t follow the same rules as in sharks.
❓Differences in reproductive strategies❓

New paper out today! 🦈
We tested whether blacktip reef shark dorsal fins are reliable for photo ID – they are!
✅ Stable over time
✅ Unique among individuals
📍Long-term dataset from French Polynesia
Led by Physioshark

🦈 New paper in Ecology & Evolution 📑 via our Physioshark research (ongoing since 2013 in French Polynesia🌺)!
Fisheries catch data can be used to unravel elasmobranch aggregation dynamics, social structures, & group behaviours. Case study: newborn blacktip reef sharks.

New potential shark nursery - part of @physioshark research, ongoing annually since 2013. How many baby blacktip reef sharks can you count?🦈
Protecting them means safeguarding the future of these incredible predators & the reefs they support! 🩵💚💙 🎞️ by @orianeservant www.instagram.com/reel/DGPhmC2...
