Lies. All lies. Hi, I'm Jake Axon. And together, we are going to discover the truth about sponges. There's a common thought that sponges overgrow corals and that the relationship they share is competition. Lies. Actually, it is quite different. A study by graduate students show that when you remove the sponges from the ecosystem of corals, 40% of the coral dies and falls off the reef. But in the areas where the sponges were not removed from the coral, only 4% of the coral died. Why is this the case? It's because the sponges hold the coral to the reef like glue. So yes, the sponge does grow over the coral, but it is only to keep the coral alive and connected to the reef. Also, did you know that corals sometimes can look like the cookie monster? Don't believe me. Okay, we'll look at this. Oh my, oh my gosh! Why? What is that? Are you kidding? I thought you were, oh my goodness, oh my goodness. And as you can see, these sponges are not those little square yellow creatures that we see on the TV shows. They can't even talk. I mean, they can't even talk. Baaaah! My life has been a lie. You thought I'd thought I'd get talking. The whole TV show and everything except the guitar. I'm fine. I'm good. I turn the camera off.
