84% of the world's coral reefs hit by worst bleaching event on record
Harmful bleaching of the world’s coral has now grown to include 84% of the ocean’s reefs in the most intense event of its kind in recorded history.

A niche #FossilFriday: the world's greatest display of Devonian actinopterygian fossils! At CMNH, it features three different genera all from the latest Devonian of NE Ohio. Might not seem like much, but that's ~15% of Devonian generic diversity in a single museum case.

Here is a video and some drone photos of the large stromatolite area at low tide. The walkway was destroyed by a cyclone a few years ago and hasn't been rebuilt. Hamlin Pools, Shark Bay, Western Australia.

I’ve been diving Victoria for 25+ yrs & never seen a blue groper west of Wilson Prom. I had heard they’re making a comeback in the Port Phillip heads and on the weekend I saw one and managed this snap one off Pt Lonsdale! I believe this is a Achoerodus gouldii
