SANDWICH (CBS) — Eighty-nine right whales, including three mom-calf pairs were spotted by the Center for Coastal Studies on March 21. That is the most they’ve seen in any one day this season.

“We had the best weather we’ve seen all season, with low winds, great visibility, and gorgeous views. We began our survey in the south of the bay, and found a relatively large group of right whales feeding just offshore of Sandy Neck, including all three mom-calf pairs,” the Center wrote on Facebook.

Another whale, Marlin, “appeared to be having the time of his life tail-slapping at the surface,” they reported.

The center is researching different food sources around the bay since whales appear to be feeding more in the southern end than further north.
