As we now know, there are five major classes within phylum Cnidaria, and we will go through them one at a time. First up is class Hydrozoa. This contains a variety of small predatory polyps, such as hydras. These are fascinating creatures which can undergo morphallaxis, or tissue regeneration. They also do not senesce, making them biologically immortal. We will also cover other fascinating organisms like siphonophores. There's much to learn, let's get started!

So, I guess, getting old and dying was a gained payoff that was worth it in exchange for all the cool stuff more complex animals can do?

Fairly new viewer, here. I ran across your debates with Hovind and Peterson and OMG-how soul draining it must have been to sit there and try to make sense of things with those brainless idiots! It's like beating a dead dog. I feel for you! Thanks for doing that! I was exhausted at the end, too!

In mammals, does tissue maintenance always induce replication of progenitor cells? Or do old cells in surrounding tissue sometimes divide to fill the gap?

Hello prof Dave i love your video. I wanna ask something, i am sorry but this out of topic. So recently someone that i know said that gravity is 4 dimension thing. This person's rationale is that gravity is capable of warping space and time. and he thinks space and time are 4 dimensional so he concludes that gravity is a 4 dimensional thing. is this true prof?. Sorry for my bad english

Long weekend and I decided to jus listen to Dr. Dave as an attempt to get ahead on my BIO 151 class. But wtf 🤯?! We covered plant life cycles thinking that was complex. Now Porifera and Cnidaria have me like sir I’m a ED Tech, we deal with HUMANS. For the love of all that normally makes sense with nuances here and there, SPEAK HUMAN! Honestly Doc, how many time am I going to have to watch this before it starts to stay in my brain long enough for me to understand because I have no clue what you’re talking about and I’m sure you’re making this up 😩🤣Glad I chose to get a head start on this😫 Thanks for the vids Doc. Not sure where to go swimming from now on tho 🤷🏾‍♂️
