Entangled Marine Mammals

Warming Oceans Increasing Whale Entanglements

“With the ocean warming, we saw a shift in the ecosystem and in the feeding behavior of humpback whales that led to a greater overlap between whales and crab fishing gear,” said Jarrod Santora, a researcher in applied mathematics at UCSC’s Baskin School of Engineering and first author of the study, published January 27 in Nature Communications.

Less than 500 North Atlantic Right Whales Remain

Last year saw an alarming dieoff of North Atlantic right whales, something researchers refer as an “unusual mortality event.” Their carcasses littered the shores of the east coast—12 in Canada and 5 in the United States. Necropsies revealed that most of the animals died from blunt force trauma or entanglement issues. This brings the North Atlantic right whale’s fragile population to an estimated fewer than 500.
