Populations of these creatures have increased rapidly within recent years, primarily due to overfishing of their natural predators, such as starfish, triggerfish and Triton's trumpet. In areas with many of these creatures, the seabed can become completely stripped of algae. As a response to this "ecological emergency", widespread culling of sea urchins has been advocated in some areas. Marine mammals of the Canary Islands include varieties of cetaceans, such as rorquals (not much known about their distributions in northeastern Atlantic), sperm
