Introduction to Ecdysozoa: Invertebrates With Cuticles

The video explores the clade Ecdysozoa, known for their molting process called ecdysis. It covers their characteristics, such as the chitinous cuticle, lack of cilia, and developmental traits as protostomes. The phylogenetic history and evolutionary relationships within the clade are discussed, highlighting studies from 1992 to 2022. Ecdysozoa's diversity and ability to inhabit various environments, including extreme ones, are emphasized. The video concludes with an introduction to the smallest Ecdysozoan phyla, starting with Loricifera.

Explain the evolutionary relationships within the clade Ecdesizoa.

What adaptations allow some ecdesizoans to survive in extreme environments?
