Did you know there are 2 types of whales? Toothed and baleen. The main difference between them is the way they feed and what they have inside their mouth. There are 15 different species of baleen whales and 77 species of toothed whales. These are some colorful and fun whale tails made on wood with resin, mica powders, seashells, sand on some, and glitter. These pieces would look so cute hanging in a doorway, patio, bathroom, office, or bedroom. Measurements are in photos. 1 tail is slightly smaller.
