Airborne marine biologists were dazzled by the diversity and abundance of large, unusual and sometimes endangered marine wildlife on a recent trip to the Northeast Canyons and Seamounts National Marine Monument, about 150 miles southeast of Cape Cod. Scientists with the Anderson Cabot Center for Ocean Life at the New England Aquarium observed dozens of dolphins mixing with schools of pilot whales plus more than a dozen of the very rarely seen and mysterious Sowerby’s beaked whales. The researchers, aboard a twin engine airplane, also spotted endangered, Moby Dick-like sperm whales as well as the second largest species of sharks in the world and the bizarre-looking giant ocean sunfish or mola mola.
