This week, the National Oceanic and Atmospheric Administration unveiled a $97 million rescue effort expected to take five to seven years. Part of the plan will include an unprecedented lab-breeding program to help revive long-spined sea urchins, a shimmering black-spined urchin, and one of the largest on the planet.

Read MoreKelp forests are in danger of disappearing with purple sea urchins gobbling up kelp at unprecedented rates. Due to a 10,000-fold increase in population levels, purple urchins are killing off the very food source that they rely on.
Read MoreCoastal kelp forests provide fertile breeding grounds for various species of fish and other organisms. Unfortunately, many of these marine habitats are disappearing faster than rainforests. Sea urchins are partly to blame.
Read MoreAbout 90 percent of the bull kelp forests, home to fish, crustaceans and other marine life, have been devoured since 2014.

Read MoreWhere once there were forests of kelp in the ocean, there is only water. And sea urchins. A combination of warm water and other ocean conditions battered the bull kelp and allowed the purple sea urchins to run wild, gobbling up everything edible on the sea floor.
Read MoreWith few natural predators, green sea urchins (Strongylocentrotus droebachiensis) have grown in numbers, grazed down large kelp forest areas in Northern Norway into urchin barrens. NIVA deployed three underwater cages outside Tromsø, Northern Norway during Autumn 2018, removed all urchins within these cages and followed the cages closely until Summer 2019.
Read MoreAn invasion of sea urchins is threatening to turn large areas of the world’s seabed into desert-like barrens. But thanks to Norwegian research, businesses now have an economic incentive to rid the waters of these destructive pests.
Read MoreWarm water and “sea star wasting disease” helped urchins take over the coast, a new study finds.
Read MorePALO ALTO, California, US -- A sea urchin ranching company has secured a sought-after permitted aquaculture facility in California, its first site in the US and hopes to begin operations by late next year.
Read MorePurple sea urchins have laid waste to Northern California coastal zones in recent years, decimating the kelp forest and ruining the habitat of other sea creatures that depend on it.

Read MoreWindstorms have whipped up wildfires across California, forcing tens of thousands to flee the inferno. But while our collective attention has justifiably focused on the fires, they aren’t the only climate change-influenced event that’s menacing the state.

Read More华盛顿 — 气候变化继续在世界海洋上留下印记。随着气温的升高，水位也在上升。温暖的海水加速了一些海洋生物的繁殖，这威胁了其他物种的生存。
Read MoreTens of millions of voracious purple sea urchins that have already chomped their way through towering underwater kelp forests in California are spreading north to Oregon, sending the delicate marine ecosystem off the shore into such disarray that other critical species are starving to death.
