The term 'whale type' encompasses four distinct species of whales: PILOT (5 letters), Sperm (5 letters), ORCA (4 letters), and HUMPBACK (8 letters). PILOT whales are the second largest members of the dolphin family and are found in all oceans. Sperm whales are the largest of the toothed whales and are known for their large heads and spermaceti organ. Orcas, also known as killer whales, are the largest member of the dolphin family and are easily recognizable by their black and white markings. HUMPBACK whales are known for their long pectoral fins and complex songs.
