With the Respiratory system, Orca's and Humans have the same respiratory system and the same way of getting oxygen through breathing and they have lungs. While Earthworms and Frogs what they have in common are that they both breathe through their skin. I also learned that animals can take aspects from one another and turn it into their way of living, like how Orcas evolved from Hippos but then they turned fully fish and got rid of the fact that they can go on land but then they got a blowhole which allows them to go above land for a short period of time without dying from lack of water. They also have really long lungs that are bigger so they can hold their breath for long periods of time because they stay underwater for a long time. They also only breathe when they want to they can't do it automatically so they don't run out of the water. We made a model of the difference between the human lungs and the Orca's the Orcas re on the left the humans are on the right. We also have 2 other models which are a frog and how it gets oxygen through the skin and a worm.
