We’ve covered origami fish as well as crabs before and in this post we’re going to be taking a look at all kinds of different sea creatures and animals found in the water.

There’s a lot of cool stuff here starting with these awesome eels. This is one of the coolest looking designs I’ve seen. I especially like how it looks when you use orange and white coloured paper like you see here. Not only do you get those awesome stripes but you get the eyes too.

This jellyfish uses a tessellation for the body which gives it a pretty cool look.

Satoshi Kamiya probably designed the coolest looking paper octopus I’ve seen. The entire thing with all the legs is folded from a single sheet of paper.

This mantis shrimp is one of the most impressive models out there. The entire thing is folded from one single sheet of paper and there are 104 steps! It took Shuki Kato over 15 hours to fold this.

These manta rays aren’t super complex but they look really great regardless. I really like how the curves on the wings make them look like they’re swimming.

This is probably my favourite shark design. The individual teeth are really awesome and so is the colour change that makes the belly of the shark white.

Here’s a very unique looking octopus that’s folded from one rectangle of paper. It was created as part of a challenge to create an octopus that doesn’t use the standard frog base. It’s pretty easy to get eight legs out of that base.
