Breynia australasiae (Leach, 1815) | |
Breynia australasiae is a species of sea urchins of the family Loveniidae, most commonly referred to as a heart urchin. [1] Their armour is covered with spines. Breynia australasiae was first scientifically described in 1815 by Leach. [2] This species is extremely common within the lagoon at Lord Howe I, although rarely sighted by divers along the New South Wales mainland. They grow up to 12 centimeters in length and can be found in waters of 0 to 10 meters deep.
Lord Howe Island Marine Park is the site of Australia's and the world's most southern coral reef ecosystem. The island is 10 km in length, 2 km wide and consists of a large lagoonal reef system along its leeward side, with 28 small islets along its coast. In 1999, the waters within three nautical miles of Lord Howe Island (465.45 km2) were declared a marine park under the NSW Marine Park Act 1997 to protect its unique marine biodiversity, with the park currently being managed by the New South Wales Marine Parks Authority. Both Lord Howe Island and Balls Pyramid are incorporated within the three nautical miles protected by the state marine park. Both marine parks complement the island's status as a World Heritage Site.
