There’s just something magical about the ocean that speaks to my soul. I’ve always lived near the water—first in Bellingham, Washington, then Vancouver, BC, and now in beautiful Hilo, Hawaii. Each place had its own ocean personality, but all of them brought me the same joy: the smell of the salty breeze, the soothing crash of waves, and the sparkle of sunlight dancing on the surface.

Maybe it’s written in the stars—both my son and I are Cancers, a water sign ruled by the moon and symbolized by the crab. Whether it’s that astrological connection or simply my lifelong love of the sea, I have always loved anything ocean themed– including ocean-themed crafts.

Today’s project is one of my favorites: a sweet and simple egg carton crab craft that’s perfect for little ocean explorers.

Why Ocean Crafts Are Perfect for Kids

Ocean crafts spark creativity while introducing kids to the wonders of marine life and ocean animals. Whether you’re homeschooling, planning a beach-themed birthday, or just trying to keep little hands busy over summer break, ocean crafts are always a hit.

They’re also wonderfully versatile—pair them with a book about sea life, turn them into a classroom project, or use them to decorate an under-the-sea themed playroom or reading nook.

Why We Love Egg Carton Crafts

If you’ve been here a while, you know I’m a big fan of upcycled crafts. Not only are they budget-friendly, but they also teach kids the value of turning trash into treasure. Egg cartons are one of my favorite materials to reuse—lightweight, easy to cut, and so versatile! Sometimes simple crafts like this one are the best crafts!

Other upcycled materials I love to keep on hand:

• Toilet paper rolls
• Paper towel tubes
• Cereal boxes
• Yogurt cups
• Jar lids
• Brown paper bags
• Paper plates
• Coffee filters
• Plastic or paper cups
• Scrap paper

Craft Cart Must-Haves: Stock Up for Creative Play

Here are some must-haves for your cart:

• Googly eyes
• Pipe cleaners
• Washable paint
• Craft glue and/or hot glue
• Kid-safe scissors

Fun Crab Trivia and Crab Facts

Want to take your ocean-themed crafting to the next level? Add a little learning to the mix with these fun and fascinating crab facts! Share them with your kids while they craft or print a few to include in your lesson plan.

• Crabs are crustaceans, which means they have a hard exoskeleton and jointed legs—just like lobsters and shrimp.
• There are over 6,700 species of crabs around the world!
• Most crabs walk sideways, but some can move forward and backward too.
• Crabs use their claws to communicate with other crabs—kind of like sign language for sea creatures.
• A group of crabs is called a “cast” or a “consortium.”
• Crabs can regrow lost limbs over time—talk about a cool superpower!
• Hermit crabs aren’t “true” crabs—they borrow other animals’ shells to live in.
• The world’s smallest crab is the pea crab, which can be as tiny as 0.27 inches.
• The Japanese spider crab holds the record for the largest leg span—up to 12 feet!
