👉 The term "ammonitoidea" refers to a group of animals that are primarily aquatic, and they have an adaptation called the "ammonito muscle," which is a type of muscle that allows them to swim. The ammonito muscle is responsible for pumping water from their lungs into their body, where it helps with respiration and digestion. This adaptation has allowed these animals to live in environments that are typically not suitable for terrestrial animals, such as rivers and lakes.
