A spectacle to behold, in the shallows, hugging this island, we see broad cowtail rays and mangrove whiprays - and looking with a close eye, few juvenile blacktip reef sharks weave between the rays.

My research uses data from the book Rays of the World, museum specimens, and taxonomic papers to develop meaningful indices of ecological function.
If you're a part of the ray fan club, let's be friends!

Wow, hi new followers ๐! I'm Rachel, a PhD Candidate with @nickdulvy.bsky.social in the @earth2ocean.bsky.social group. My research explores the ecofunctional morphology of sharks and rays, so I'm working on connecting what species look like to the role they play in their environment.

A school of ghostly blue and white squid float in midnight blue water, their bodies blurred by their fast movements through the sea. The each have large, round black eyes that almost seem to catch the light and reflect back in a silvery shine, long arms that are tucked in closely together to be more streamlined, and a small siphon pointed downwards and to the left. On the image is a logo for the game FathomVerse, with a caricature of a crab made of bubbles next to it.
๐พItโs finally here! ๐พThe community science mobile game that weโve been working on with our fronds at FathomVerse and @mbarinews.bsky.social is now available for FREE in the Google Play and Apple App stores! Download it here: www.fathomverse.game

What a great weekend for E2O!
The Palen & Cรดtรฉ labs made waves at #PEEC2024 at the Bamfield Marine Sciences Centre.
Meanwhile, the Dulvy lab shared insights at #NEPSSVI at the Seattle Aquarium.
From local invasive species to global protected areas, we are passionate about sharing our science! ๐๐ฆ
