New ocean dwellers arrived millennia — maybe decades — after the Chicxulub impact. That forces a rethink of evolution's response to wipeout events.
Summer is a time for sun and sand. If you live inland, build your own mini beach in this science experiment.
The first global mapping of macroalgae blooms in the ocean, last year, reveals rapid growth and a new record for the area seaweed blankets.
Scientists found nests organized into curves, clusters and ovals on the Antarctic seabed. Such groupings may protect the fish eggs from predators.
The corals offer a dire warning, scientists say, and suggests that more such catastrophic points of no return could occur soon — some within a decade.
Could these colorful fish aid struggling coral? Yes, but not always. Parrotfish play a complex role in reefs — and sometimes may cause harm.
Humans have driven sharks and their cousins to the brink of extinction, but it’s not too late to turn the tide. At stake is the health of the entire ocean.
