17 Adorable Sea Creatures Free Crochet Patterns (easy!)

Below are 17 sea creature creation you make easily and for free! Almost all of the patterns are suitable for beginners and use typical amigurumi stitches such as magic ring, single crochet, and slip stitch to name a few. 

It is stated whether each pattern uses US terminology for the crochet terms and will state whether what it is otherwise. The patterns are all beginner friendly, so most of them will be quick to make. 

There are a range of sea creatures below, most of which are primarily found in the deep sea, as well as a couple cute creations such as a particular marine bird that everyone is sure to love! 

I hope you get inspired and start making your favorite sea creature from the below list straight away!

4. Shark

Free pattern by Lovely Craft

This shark comes out pretty tiny at 8cm long and so could almost be called a baby shark! This pattern has some simple color changes to create the two-toned body and has very clear instructions on how to do this.

This little guy could be turned into a friendly shark keychain to keep on your keys or bag!

5. Humpback Whale

Free pattern by One Dog Woof

This humpback whale pattern is slightly more complex than some other sea creature patterns on the list, but the end result is absolutely worth it!

It is created using two colors of yarn and crocheting rows that are sewn together later to enhance the typical shape or a humpback whale shape and mouth.

The pattern is very clear and there is even a video to help people follow the pattern and have the most common asked questions on the pattern answered.

6. Clown Fish

This octopus makes for a very friendly amigurumi toy for children and adults alike. The pattern can easily be customized on color and you could add a baby rattle to the head if you wanted to make this octopus for a child!
