Welcome to Sea Monster Week on Tor.com! In honor of the launch of Shark Week over on the Discovery Channel, we’ve decided to dive into the world of some of our favorite creatures ever with articles, book excerpts and more.

But just what is a “sea monster” anyway? Well, we’ve given ourselves a pretty broad definition to work with. Here’s the Stubby the Rocket definition:

Sea Monster (noun): Any sufficiently awesome water-dwelling creature that we perceive as being monstrously cool.

So, with that in mind, prepare yourself for the greatest A-Z list of sea monsters ever compiled, just below the surface of this blog.
