Like so many of my other PowerPoints, this one is full of big, colorful pictures and multiple choice question slides with the answers on their own slides. I love to use these PowerPoints as reviews. The kids and I use them as "game shows." This one includes starfish, seahorse, manatees, loggerhead turtles, clown fish, flying fish, octopus, squid, jellyfish, whales, dolphins, orcas, beluga whales, blue whales, manta rays, sting rays, sharks, and their relatives. THIS POWERPOINT HAS 50 SLIDES!!! I have lots of other PowerPoints in my store, Jacoby Jungle. Thanks for looking!
