This green and yellow slug (Ibycus rachelae) was discovered on leaves in a mountain forest at altitudes up to 6,233 feet (1,900 meters) in Sabah, Malaysia. The slug sports a tail that's three times the length of its head, which it wraps around its 1.6-inch-long (4 cm) body as if a pet cat. In fact, its discoverers initially planned to name the slug Ibycus felis, after its feline inspiration. Instead, they named it after the girlfriend of one of its discoverers, Menno Schilthuizen of the Netherlands Centre for Biodiversity 'Naturalis.'
