Meet Our Whales

 

Many species are commonly found off our coast!

There are at least 85 different species of the order cetaceans: whales, dolphins and porpoises. They are divided into two sub-orders: baleen and toothed whales. Baleen whales include the humpback, blue, fin, and minke whales. These animals have two blowhole openings on top of their head and have baleen plates hanging from their upper jaw. These baleen plates help whales filter lots of small fish and plankton out of the water. Toothed whales include the sperm whale, beaked whales and all the dolphin and porpoises. These animals have a single blowhole opening and between 2-112 teeth in their mouth. They use their teeth to capture one bigger fish, squid or other marine mammal (in the case of the orca). Below is a list of species that we see off our coast. The first group listed, we commonly encounter, and the others are seen only occasionally.
