prickly problem with sea urchins

Abstract/Description: Beneath the waves, once towering kelp beds are collapsing from an unprecedented perfect storm that has been brewing below the surface. First, a massive epidemic wiped out sea stars, then a marine heatwave and El Niño, and now an explosion of sea urchins. This means bad news for kelp. The combination of abnormally warm water and a huge numbers of sea urchins have taken a toll on once healthy kelp beds.
