Mullion Island (Cornish: Enys Pryven, meaning worm island) is an uninhabited island on the eastern side of Mount's Bay, Cornwall, in the United Kingdom. It is approximately half a mile (0.8 km) offshore from Mullion Cove, 1 mile (1.6 km) in circumference and the highest point is 118 feet (36 m) above sea level. It forms part of the Lizard Peninsula Area of Outstanding Natural Beauty and is within the Mullion Cliff to Predannack Cliff Site of Special Scientific Interest.
The island was formed 350 million years ago, in a fashion similar to the mid-Atlantic ridge today, where lava flows from a split in the earth's crust, and cools rapidly to form large lumps known as pillow lava. Mullion Island was formed by a separtate (later) volcanic episode than the nearby Lizard complex rocks. The soil is highly manured by bird droppngs, rich in nitrogen and phosphate, and sea beet (Beta vulgaris subsp maritima) and tree mallow (Lavatera arborea) are the dominate plants. Great black-backed gull (Larus marinus) breed on the island, along with common guillemot (Uria aalge), Eurasian oystercatcher (Haematopus ostralegus) and possibly razorbill (Alca torda). European shag (Phalacrocorax aristotelis) and great cormorant (Phalacrocorax carbo) were also on the island during a visit by West Cornwall Ringing Group on 16 June 2015.
