The coral reets of Marsa Alam are thriving underwater cities, built by tiny coral polyps over thousands of years.
These reefs provide shelter and food for countless marine species and play a crucial role in the ecosystem.

Shout out to my marine biologist son Rob who was brought in to address a reef infestation. He removed 189 crown of thorns starfish (reef-destroying parasites) in ONE DAY!! Now for the longer game: educating the local team to control the marine ecosystem themselves.

Omani authorities said they have launched a "comprehensive response" to secure the Caroline Bezengi vessel and mitigate the impact on the marine ecosystem and maritime navigation.

This is wild: the authors find evidence for giant, macro-predatory octopuses in Late Cretaceous oceans that might max out at *62 feet long,* comfortably large enough to attack, kill and eat mosasaurs
Earliest octopuses were giant top predators in Cretaceous oceans
Top predators drive changes in ecosystem structure. For the last ~370 million years, large-sized vertebrates have dominated the apex of the marine food chain, while invertebrates have served as smalle...

This is just so terribly sad. A marine ecosystem dying before our eyes.
Footage captured yesterday at Ardrossan, Yorke Peninsula, reveals more underwater impacts of SA's Harmful Algal Bloom.
With neon green water, the seabed was littered with dead and dying animals. There were also hundreds, if not thousands, of garfish on the seabed, some still alive.
