USM Whale Researchers Find Little Oil in Gulf of Mexico, Maine Public Radio, November 23, 2010:
[University of Southern Maine Center for Toxicology and Environmental Health director John] Wise says he's worried that dispersant is being consumed by krill, squid and other marine life that whales eat.
"If only a handful of whales can't reproduce because of broken DNA, the whole population will be doomed because it's so small--not doomed tomorrow, but doomed over a period of decades," Wise says.
"The population estimates suggest if you lose three to five adult sperm whales, you lose that population. It takes them a long time to reproduce, they don't have a lot of young."
