1 The Otter Project & MPA Watch More Than a Cute Face How do otters keep warm in our cold California waters? What do otters eat? How do otters sleep? What dangers do otters face? Why should otters be protected? What can you do to help otters? Keeping warm No blubber, it s all about that FUR! o 1,000,000 hairs per square inch. Humans have a tenth of that on our whole heads if we re lucky o Fur has two layers, a short under layer and a longer top layer of guard hairs. Guard hairs trap air and insulate against cold water. o Otter pup life vest. Sea Otters Are Expensive Dates Otters Must eat 25-30% of body weight daily so must be efficient food gatherers o If you weigh 150 lbs you d have to eat about 37 to 45 pounds EVERY DAY. An adult otter weighs 40 to 60 pounds, eating 10 to 20 pounds of food each day. Otters eat shellfish o How do they crack the puzzle? Tools! An otter will sometimes use the same rock over and over again. Where do they keep it? 1

2 Sleeping in the Ocean Cannot sleep all night, instead they take lots of naps. When ready to nap otters sometimes wrap themselves in kelp to avoid drifting away. Sleeping groups of otters are called rafts and can be as small as a couple otters or as large as over 100. Never disturb a sleeping otter! What Threatens Sea Otters? Quality habitat Pollution o Disease o Domoic Acid o Pesticides o Parasites Oil Spills o Could wipe out entire California sea otter population Why Protect Sea Otters? Sea otters are a keystone species o Keep marine herbivores in check o Kelp forest gardeners Sequester carbon Protect shoreline Provide habitat Sea otters are a sentinel species o Eat filter feeders Bioaccumulate toxins What can we do to help? Pollution o Buy organic o Reduce, reuse, recycle, and refuse Oil spills o Walk, bike, electric or hybrid cars, bus or trains o Ban the bag! Over a cup of crude oil to make a single plastic bag. Nationwide, each person uses about 250 plastic bags each year. Use cloth bags you and conserve15 gallons of oil. Vote VOLUNTEER! 2

4 Levels of Protection State Marine Reserve (SMR) The most restrictive classification, these are no-take areas. State Marine Park (SMP) May allow recreational take, or limit in some way, but does NOT allow commercial take. State Marine Conservation Area (SMCA) May limit recreational and/or commercial take to protect a specific resource or habitat. Benefits of MPAs Science proves that MPAs allow fish to thrive by protecting ecosystems, not just individual species. Reduced human disturbance. MPAs leave the vast majority of the coast open for fishing. Increased biodiversity Species can grow & reproduce Bigger Fish More Fish MPA Watch MPA Watch is a citizen science program Volunteers collect scientific data on coastal and marine resource use Collected data helps inform MPA management 4
