Researchers recently discovered harmful algae toxins in Alaskan whales, walruses, sea lions, seals, porpoises and sea otters. Their findings represent a staggering northward expansion of such toxins, although (for what it is worth) they have not yet reached concentrations harmful to human health.
A newly launched search in Mexico's Sea of Cortez has reportedly found several vaquita marina porpoises, one of the most critically endangered animals in the world. This reassures conservationists that the vaquita isn't extinct yet. However, that doesn't mean the tiny animals are in good shape.
