👉 The term "Aeschnidae" is defined as a family of small to medium-sized terrestrial mammals found in North America, primarily inhabiting temperate forests and wetlands. These animals are known for their distinctive, slender bodies with long ears that help them hunt insects and other small prey. Aeschnidae includes several species, including the common eel bear (Aeschnia aethiops), which is found in mountainous regions of North America.
