Cetacean Index Sticker

Cetaceans will float their heads out of the water to observe the situation on the sea. This behavior is called: peeping. Doesn’t it look like hiding in a sea of books and peeping in the use of notes? I have drawn the teeth of the false killer whale! There are a total of 12 species of cetaceans, all of which can be seen in Taiwan! From top to bottom: spinner dolphin, false killer whale, humpback whale, tropical spotted dolphin, blue whale, patterned dolphin, bottlenose dolphin, Freund's dolphin, sperm whale, Cuvier's beaked whale, killer whale, pilot whale. I have drawn a small diagram for reference on how to use it
