When a right whale is spotted, everyone on the boat instantly jumps into action. Cameras are passed to the two observers on the bow, the "whale watcher" takes notes about any behaviors and works to identify individuals, and the rest of the team carefully watches to keep track of the whale as well as look for others nearby.

A right whale with broken callosities and a mud-covered head was found peacefully skim-feeding at and just below the surface. When feeding, right whales open their mouths and glide through the water so that their baleen traps tasty plankton. When they dive down to layers of plankton at depth, they sometimes hit the seafloor headfirst and get covered in mud. To find out what species of plankton this whale was eating, we dragged a net from the stern for a few minutes to collect a sample and it quickly filled with plankton.

We followed the whale, identified as Catalog #3991 (a female born in 2009), and soon she joined a second right whale, identified as #3401, Tux. Tux is a male born in 2004 to #1701, Aphrodite. The pair traveled together and seemed playful, as some rolling was observed. We stayed with them until we had enough photographs to match them to individuals in the Catalog and to visually assess their body condition.

Although we did not see more right whales the rest of the day, we saw a pod of over 100 white-sided dolphins, several large ocean sunfish and jumping tuna. We hope for more right whale sightings on our next day out!
