Abstract
Batillaria attramentaria (Sowerby), a recent introduction to North America from Japan, occurs on tidal mudflats from California to British Columbia. A population of this deposit-feeder was followed for 10 yr on Galiano Island, British Columbia by recovering marked individuals and by following shifts in size-frequency distributions. Growth as well as erosion pattern and age class analysis indicate that the average size of B. attramentaria in the first 6 yr of life is 3, 9, 12, 15, 17, and 18 mm in length and that longevity falls between 6 and 10 yr. Recruitment of young B. attramentaria occurred every year. The key to B. attramentaria's success must lie in its combination of both a relatively predictable annual recruitment and a moderately long longevity.
