Would you look at this then another brand new episode of the Fun Kids Science Weekly? Thank you for listening. Welcome along. This is the show that explores everything amazing, epic, dazzling and deadly that's in the universe.

My name's Dan. Now, today we'll learn about one of the most poisonous creatures in the ocean.

Also, you can hear what your brain is actually made of, you know, apart from loads of TV, ice cream and barbecue food, because it's the end of summer.

It's probably full of that.

And also, we'll chat to a man who was written a book on the most dangerous creatures in the world.

First, we're catching up with our amazing Age of Dinosaurs series and heading to the Cretaceous period.

Imagine going back in time, not 100 years or 1,000 years, but millions of years.
