Lophotrochozoa

Lophotrochozoa is a large group of animals within the animal kingdom that share common features in their development and body structure. This group includes diverse animals like mollusks (clams, snails), annelid worms, and others. They typically have a specialized feeding structure called a lophophore or go through a developmental stage called the trochophore larva. These animals are found in many habitats, from deep oceans to terrestrial environments. Understanding Lophotrochozoa helps scientists learn about the evolutionary connections among different animal groups and how complex body plans have developed over time.
