Medicine & TechnologyWhile the presence of small pink roses may seem like an innocuous blossom, researchers from the University of California, Santa Cruz are finding that as little creatures appear they signal warmer waters to come. No, these pink roses aren’t flora species, they’re hot pink sea slugs found traditionally in southern California tide pools. But as they’ve migrated north, researchers now believe that coastal water temperatures are on the rise, and this could have serious implications farther up on the food chain.
