👉 The term "chaetognath" refers to a type of marine mammal that is not known for its diet, but instead feeds on small crustaceans and other invertebrates. These animals are often found living in bodies of water near shorelines or rocky areas, such as estuaries and mangrove swamps. They have been described by scientists as "amphibians" due to their skin-like appendages that help them adapt to the environment they live in.
