The gray whale’s skin secrets small droplets of an oily substance which also helps reduce drag and increase speed. In doing so, they often leave long trails of mud behind them and "feeding pits" in the sea floor. We continue to monitor the abundance and calf production of the stock, especially in light of recent climatic changes occuring in their arctic feeding grounds. In stock Please select a color.

UAS photographs are also being evaluated for matching individual whales from aerial and shore-based photo-identifications based on their natural markings. International conservation measures were enacted in the 1930s and 1940s to protect whales from over exploitation and in the mid-1980s the International Whaling Commission instituted a moratorium on commercial whaling. It has been said that this whale species may have decreased in overall size due to the large amount of whaling in the past. Little else is known about the mating behavior other than the fact they partake in group mating events. The Unmanned Aerial Systems (UAS) program at NOAA Southwest Fisheries Science Center has been at the forefront of the development and application of UAS technologies within the marine wildlife research community for over a decade. www.decorpad.com.
