16 Awesome Free Crochet Sea Creature Patterns
My crochet sea creature patterns are all beginner friendly, but present opportunities for practising some different techniques and styles. A bit of fun for any level of crocheter!
You’ll mostly be working from a central magic circle, in increasing and decreasing rounds of single crochets. But you’ll find some amigurumi sea creatures have extra details through hand sewing or surfacing crocheting to really bring them to life.
Crochet Puffer Fish Pattern
I am a bit obsessed with my puffer fish. This pattern was so quick to design, and you’ll find it takes just a few hours to work up. Even less if you’re a speedy crocheter!
I named this pattern after a local reptile store’s resident pet Mbu puffer, Mr Puffy. I wanted it to be simple to crochet, yet have those important details that make it immediately identifiable as a puffer fish.
You’ll make the ridges on the body using two strands of yarn and a wide eyed tapestry needle, weaving in and out four times over a space two stitches wide. The gaping mouth is achieved using back and front loop only crochet.
You’ll need 1.8oz of DK yarn, and a 3.5mm crochet hook for this one.

My Amigurumi Seal
My low-sew crochet seal looks a lot more complex than it is. The speckled fur pattern is achieved with a variegated yarn, so there are no color changes as you go along. It’s a great novice crochet pattern, or a fast project for an expert!
I created this crochet design for my wonderful sister in law, who is a huge fan of seals. So it needed to be cute, but with the decorative look of a good gift for an adult!
You’ll need to grab a small skein of DK yarn, and your 3.5mm crochet hook for this pattern.

Keychain Seal
And if bigger plushies aren’t your thing, I’ve also got a tiny crochet seal! It’s a rather different style of pattern, but I’m equally proud of the finish on this miniature version.
To make this teeny friend you’ll need some grey DK yarn, 10mm safety eyes and a dainty 2.5mm crochet hook.

Tiny Crochet Octopus
And whilst we’re on the small theme, dive down into the ocean and scoop up an itty bitty octo buddy! I created this pattern as a really quick and fun stand alone crochet project, but you can just as easily add this one onto a keychain too if you like.
To create your own octopus just like mine you’ll need about 30g of DK yarn and a 2.5mm crochet hook.

Crocheting a Squid
This cute crochet squid pattern is a simple design with a characterful finish. It’s mostly worked from a magic circle, with even increases and decreases. I throw in a bit of back look crochet to give the divide above the eyes, and most of it is completely unstuffed.
You’ll need a small hank of pink aran weight yarn, and some scraps of cream aran yarn for the surface crocheting details and the bold eyeliner. You will mainly work with a 4mm crochet hook, swapping to a smaller sized 3mm hook for the surface crocheting stitches.

Jellyfish Crochet Plushie
Loving the pink theme? Then you’re really going to like my next pattern, the jellyfish! I really lent into the color theming with this one, with just a few touches of cream yarn to make the tentacles pop and to give some expression to the eyes as well.
For this pattern you’re going to need worsted weight yarn and a 4mm crochet hook, along with your usual kit and 12mm safety eyes.

How to Crochet a Sea Otter
My crocheted sea otter lays on his back, ready to much down some molluscs! It’s another simple, speedy yet defined amigurumi design. There are some minor color changes, and a little bit of hand sewing.
Tiny ears and wide eyes make this one really give off the essence of the sea creature it’s honoring. You’ll need a 4mm crochet hook, and aran yarn in pale and dark brown shades. A scrap of dark gray or back yarn for the nose will bring it all together.

Crochet Whale Pattern
What’s more iconic in the ocean than the massive blue whale? This ode to the most magnificent of sea creatures is one that I was really pleased with for a few reasons. Firstly I wanted to give off the impression of an expression without needing to make a specific mouth, and secondly I used unstuffed pieces to create texture in a way I’ve not really experimented with before.
I used worsted weight yarn and a 4mm crochet hook for this project.

Manatee Plushie Pattern
Want something a little more unusual? Then why not have a try at making your own manatee! I am totally in love with the adorable sea cow, that looks a bit like a seal caricature but with even more character!
To make your own you’ll need some grey DK yarn and a 3.5mm safety hook.

Crochet Seahorse Pattern
This amigurumi seahorse pattern is bright, bold and distinctive. There are a few more intermediate level aspects, but the extra descriptions will allow even relatively new crocheters to join in.
The tail is curled with a combination of crochet stitches and hand sewing, and you’ll detail the crest with some surface crocheting.
You’ll need blue/gray and pale gray double knitting yarns, and a 3mm and 2.5mm crochet hook.

Amigurumi Polar Bear Cub Pattern
Okay, so it’s not technically a sea creature but this crochet pattern celebrates the bear most associated with the ocean! My fluffy crochet polar bear cub pattern uses huge safety eyes and fine claw details to bring a simple design to life.
You’ll need 50g/1.8oz of worsted weight chenille yarn, and 4mm crochet hook. Magic circles can be a little tricky with this yarn fiber, but you can use the chain two method if you find you have trouble closing your loops.

Crochet Sea Turtle Design
Another chenille design, this sea turtle might just be the fastest crochet pattern in the sea creature collection. The basic shapes go together beautifully to create a soft, cuddly crocheted toy.
You’ll need three skeins of yarn for this one – I used King Cole’s Yummy chenille yarn in liquorice and champagne shades, and the Jubille yarn in zen. Work it all up with a larger 5.5mm crochet hook.

Amigurumi Walrus Pattern
This is perhaps my most unusual crochet sea creature pattern – the wonderful walrus. The details are created using hand sewing, extra magic loops and loosely sewn yarn threads.
You’ll work this design in DK merino blend wool, in a red/brown shade, a dash of cream acrylic DK yarn, and a 5mm and 4mm crochet hook.
Axolotl Plushie
What could be more fun than a crocheted axolotl? My bestie Sarah created this adorable pattern for our website, and I absolutely adore how it’s turned out. And the best part is it’s incredible beginner friendly and quick to work up too.
It’s made in a plush yarn, for that extra squash and squeeze!

Keychain Axolotl
And if plush yarn isn’t your thing (it’s not mine!) then this miniature axolotl is a different take on the same cute creature. You’ll need DK yarn and a 2.5mm project to creature this pocket pal.
Crochet Goldfish
And last but not least, my most recent sea creature pattern is this goldfish style pet fish! It uses two colors of DK yarn, a 3.5mm hook and works up really quickly. The ideal last minute gift project!
