While manatees in the United States today are more associated with the state of Florida, a relative of theirs once swam the seas along North America’s Pacific coast. Millions of years ago, the Steller’s sea cow (Hydrodamalis gigas) grazed in the kelp forests along the Northern Pacific Ocean and the Bering Sea. This marine mammal is part of the Sirenia order that includes present-day manatees. It could weigh up to four tons and grow to lengths of 26 to 30 feet—much longer than today’s manatees. It grazed along the Northwest’s mighty kelp forests, which today stretches from Baja California, Mexico up the Pacific coastline to Alaska. The sea cow ate huge quantities of kelp from the upper canopy of kelp forests, which allowed needed sunlight to travel down to the forest’s understory.

What a tangled web we weave. When it comes to the impact of the climate crisis on marine food webs, we apparently have not known the half of it. That's according to a new University of Nevada, Las Vegas (UNLV) study, which compared ancient and modern ocean ecosystems in a bid to understand how to make them healthier and more resilient.

For millions of years, the Steller’s sea cow, a four-ton marine mammal and relative of the manatee, shaped kelp forests along the Pacific coast of North America by eating massive quantities of kelp fronds from the upper canopies, thus allowing light to spur productivity in the understory. In a paper published today in Frontiers in Ecology and Evolution, researchers from the California Academy of Sciences—as part of the Academy’s Thriving California initiative—reveal what historical kelp forests may have looked like in the presence of the marine megaherbivore, which went extinct in the 1700s just 27 years after its first encounter with Europeans due to overhunting, and suggest how kelp forest conservation efforts can take its absence into account.
