Invertebrate Chordates Part 1: Subphylum Cephalochordata (Lancelets)
Professor Dave Explains
@professordaveexplainsAbout
Welcome! I have a knack for explaining stuff and I want to share some knowledge with you. I received a BA in chemistry from Carleton College, and performed graduate studies in both synthetic organic chemistry and science education at Cal State Northridge, receiving an MA in the latter. Prior to this I taught for about a decade in various high school and undergraduate settings, specializing in organic chemistry but also teaching general chemistry, physics, and biology. This channel is for students at the high school and undergraduate level, but it is also for members of the general public who just want to know more about the world and how things work. My goal is to increase science literacy in our society, so please share these tutorials with anyone that you think might enjoy them. Happy learning!

Video Description
Many people presume that all members of Chordata have a backbone, but that actually is not true. Vertebrates have backbones, meaning members of subphylum Vertebrata. There are two other subphyla within Chordata, those being Cephalochordata and Tunicata, and these are considered invertebrate chordates. Let's take these one by one, starting with Cephalochordata, also known as the lancelets.
