Canaries are generally divided into three main groups: While wild canaries are a yellowish-green colour, domestic canaries have been selectively bred for a wide variety
Marine life of the Canary Islands the most commonly seen invertebrate in Canary Island waters, the lime urchin is, ecologically, a very not important herbivore. 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.
