We are passionated about Otters
‘Otters are truly extraordinary. I challenge anyone to watch a group of them for more than ten minutes without becoming captivated—often for life. What makes them so fascinating? In reality, they are fierce aquatic predators and skilled fighters when necessary, far from being merely cute or cuddly. Yet, a short-clawed otter can spend hours playing with a pebble, effortlessly tossing it from hand to hand. North American otters gallop and slide across the snow, joyfully chasing one another. Giant otters build lifelong bonds with their family members. Sea otters use tools and even hold on to each other while floating, so they don’t drift apart in the ocean.’
