Researchers at the New England Aquarium are moving forward in their mission to save the critically endangered North Atlantic right whale, and have recently discovered another potential threat to this small population of 400 whales.
It is widely known that whaling decimated these whales before they were protected in 1935 and that deaths and injury from vessel collisions and fishing gear interactions are the major culprits in this century. However, what is less widely known is that compromised reproduction is also limiting the recovery of this species, leading researchers to look to the environment for the cause.
Aquarium scientists are currently looking closely at a marine biotoxin produced by algae called domoic acid, or DA. DA is a potent neurotoxin that is commonly found in shellfish and has caused deaths and serious illness in humans, as well as thousands of deaths, neurological disease and abortions and stillbirths in California sea lions.
A right whale’s natural diet consists of huge amounts of copepods
