Unusual Surge of Tuna Crabs Invades Southern California Waters

Marine biologists link the phenomenon to changing ocean currents and possible climate change effects.

Thousands of tuna crabs have been observed off the coast of San Diego, far from their usual habitat in Baja California.
Experts suggest that stronger-than-normal ocean currents, potentially linked to El Niño, are sweeping the crabs northward.
The crabs are not strong swimmers and are easily carried by currents, leading to mass strandings on beaches.
While the swarms provide a temporary food source for local marine predators, the crabs often perish in the cooler waters.
Scientists emphasize the need to understand the complex impacts of climate change on marine ecosystems.
