California Scrambles to Wipe Out Algae Invader
Species that can overtake habitat has been spotted in state waters for the first time
- For the first time, scientists say they have seen a species of bright green algae growing in the waters off California—and they are hoping it's the last. The invasive algae can overtake the environment and displace critical food sources for ocean animals on the southern California coast. A...

Shark Populations Have Collapsed Since 1970
They're down by 71% globally, researchers say
- Scientists have known for decades that individual shark species are declining, but a new study drawing on 57 global datasets underscores just how dramatically worldwide populations have collapsed in the past half century. Globally, the abundance of oceanic sharks and rays dropped more than 70% between 1970 and 2018, according...

Purple Sea Urchins Are Causing West Coast Nightmare
They've already wiped out 90% of northern California's underwater kelp forests

Incredibly Rare Pocket Shark Caught in Gulf
Only previous catch was 36 years ago

Beautiful but Toxic 'Sea Sparkle' on the Rise
'Magnificent' sight caused by farm pollution
- Eerie fluorescent blue patches of water seen glimmering off Hong Kong's seashore are magnificent, disturbing, and potentially toxic, marine biologists say. The glow is an indicator of a harmful algal bloom created by something called Noctiluca scintillans, nicknamed "Sea Sparkle." It looks like algae and can act...

Antarctic Fish Have Ice in Their Veins
Antifreeze proteins appear to prevent melting
- How do the fish that thrive in the waters around Antarctica prevent their blood from turning to ice? Turns out at least some of them don't. Scientists have long known that the group of fish species known as notothenioids have an antifreeze protein in their blood that prevents them...
