👉 The term "cochlidiidae" refers to a group of marine invertebrates that belong to the family Cochliidae. These animals are characterized by their short, flattened bodies and long, flexible tails, which they use for swimming and other aquatic activities. The cochlidiids also have a unique adaptation called the "cochliid gill," which is a small, flexible tube-like structure that is used to capture food particles and filter them through the water column.
