摘要Abstract
This article reports unusually high density and abundance of the black sea cucumber Holothuria atra on an intertidal reef platform at “Duzaiping,” a reef off Hsiao Liouciou Island (22°20′55″N, 120°21′49″E), Southern Taiwan. Density reached 80.75±11.94 individuals m-2 (mean±std.dev; n=10), with the average being 5.60±1.42 individuals m-2 (n=20); both values are the highest ever recorded, and 198,240 sea cucumbers were estimated to be present across a 35,400 m2 study area. The high abundance of the sea urchin Echinometra mathaei, which can provide abundant food (sand) and shelter to H. atra through its extensive burrowing activity, could explain these high densities and total numbers, as could the ability of H. atra to reproduce via binary fission.
