The first-ever footage of Narwhals using their tusks for feeding

Canadian researchers and partners have exciting video evidence that shows what narwhals use their tusks for: feeding. Watch as four researchers from Fisheries and Oceans Canada explain how they managed to capture the first recorded evidence of this behaviour and what it means for future research.

I’m Sarah, 22 and live in Ontario. Hoping to meet some nice people this is my first time posting on gwlg :).

I’m a Fisheries Research Tech so I pretty much spend all day everyday playing in the water and nerding out about fish.

Other things I nerd out about: Nature, camping, paddling, shorts and tee shirt weather, coffee, dogs, girls.

Help me, all my friends are straight!

Scientists on research vessel spot rare whale in the Bering Sea

By Dan Joling, August 11, 2017

Federal researchers studying critically endangered North Pacific right whales sometimes go years without finding their subjects. Over the weekend they got lucky. A research vessel in the Bering Sea photographed two of the animals Sunday and obtained a biopsy sample from one, the National Oceanic and Atmospheric Administration announced Thursday.

NOAA Fisheries research biologist Jessica Crance was on board the Yushin Maru 2, when the whales were spotted. The ship is part of the Pacific Ocean Whale and Ecosystem Research program, a collaborative effort headed by the International Whaling Commission. Using an acoustic recorder, and between sounds of killer whales and walrus, Crance picked up faint calls of a right whale east of Bristol Bay, Alaska.

The sounds came from an estimated 10 to 32 miles (16 to 51 kilometers) away and the ship headed west, she said in a blog entry. After four and a half hours, despite the presence of minke and humpback whales, and only a few calls from the right whales, the rare animals were spotted.
