| Abstract |
In May, 1988, a volcanic eruption at Gunung Api in Banda, Maluku, Indonesia, flowed into the sea, building small new headlands of boulders and cobbles. Thecooled flow provided ideal conditions for fringing coral reef growth by creating a well-lighted hard surface extending seaward from the former shoreline. It was estimated that the maximum radial extension of Acropora sp., probably A. hyacinthus, was 14 cm/yr as of November, 1996. The largest of 7 living gastropod species observed was Haliotis asinina (shell length 6.3-8.1 cm), followed by Latirolagena smaragdula (to 4.5 cm) and 5 Conus species 1.2-3.3 cm in shell length. The largest L. smaragdula and C. lividus were about 10% larger than expected for 8 year old animals according to published growth curves from the Great Barrier Reef. However, H. asinina could have attained the maximum observed shell length in as little as 3 years, were its growth curve similar to those published for the same species under culture conditions in Thailand and Philippines. |
