Invertebrates Biology Writing Lab

..Hello? Is this thing on?
Ah, okay. Good.

Hello everyone and welcome back to another blog post! A couple weeks ago I told you all about vertebrates. You know, organisms that have those weird things called backbones? Yeah, those guys.
Pfft. Weirdos. Who needs backbones nowadays anyway.

Well anyway, today we're going to be talking about their relatives that don't have backbones, the invertebrates!

In case you haven't caught on at this point, an invertebrate is the exact opposite of a vertebrate. Meaning they lack backbones. Invertebrates outnumber vertebrates by a staggering number (see my vertebrates post for more information), but they mostly consist of insects.
Creepy crawleys.
The things that keep your hand out of that suspicious hole in the ground.
Yeah, those guys.

Along with insects there are also mollusks (including clams, octopi and squids), crabs, worms and jellyfish. Granted jellyfish don't have any bones, let alone backbones, but you get the idea.

If I were to pick my favorite invertebrate however, it'd have to be the Blanket Octopus.
Yes, you heard me correctly. I actually think I did a post on these guys once...
Anyway, Blanket Octopi are a type of octopus (der) that lives in the open water of the Indian Ocean, which is uncommon for an octopus. This is because Blanket Octopi look like, well, blankets. Or floating debris. Their 8 arms have multiple layers of skin connecting them to each other, allowing the Blanket Octopus to look like a large leaf floating in the ocean, or debris, or some random blanket. This is very effective at confusing predators. But if their disguise doesn't work, they can simply detach a bit of their webbing to distract a predator.
Furthermore, if THAT doesn't work, they can still shoot ink out in defense like any other octopus.
Not to mention they're a beautiful shade of red! What's not to love!

Well, that just about wraps up my blog post on invertebrates. I hope you learned something today, and I shall see you all in the next post. Buh-Bye!
