Ecklonia radiata, commonly known as spiny kelp or leather kelp, is a species of kelp found in the Canary Islands, the Cape Verde Islands, Madagascar, Mauritania, Senegal, South Africa, Oman, southern Australia, Lord Howe Island, and New Zealand. Ecklonia radiata grows in kelp beds on reefs and where sheltered can form dense 'forests'. It can be found in the low intertidal zone to depths of approximately 25 metres (82 ft) and rarely exceeds a body length of 1 metre (3 ft 3 in).
