“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.
Entangled Marine Mammals
Seismic blasting used in oil exploration can reach 250 decibels and be heard for miles. It can cause hearing loss, disorientation and disturb essential marine mammal behaviors such as feeding and breeding. Just over 300 Cook Inlet beluga whales are left after four more washed up dead in Cook Inlet in the past two weeks.
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.
Colossal numbers of plastic bottles and bags float around the earth, and their severe impact on marine life has been extensively documented. But there’s another, lesser-known killer plastic lurking in our oceans. Every year, more than 136,000 whales, dolphins and… Read More ›
