Sea Creature Costumes
Tentacles, flippers, and fins—the world beneath the sea is filled with life that looks like something from an alien planet! It's a wonder that we can know so little about some of the very animals that share this Earth with us. Researchers like Jacques Cousteau spent their lives trying to unlock the mysteries of the deep, after all. And it's only because of the hard work of sailors, marine biologists, and deep-sea divers that we know as much as we do about those animals. Well, we mixed our fascination with life under the sea and our extensive knowledge of costuming to create a great selection of costumes based on your favorite underwater critters.
Of course, it can be a little challenging to make a choice with such a wide selection! Do you want to dress up like an enigmatic squid from the depths or a cute narwhal cruising the coast? Maybe you want to be an apex predator of the seas and wear one of our many shark costumes. Well, we want to help you make your choice! This guide will help you weigh your options and choose the right sea creature costume for you.
Let's start with sharks. Sharks are known as some of the fiercest predators in the ocean. Thanks to Jaws and Finding Nemo and the ever-popular Shark Week, everyone knows the awesome power of sharks! Aside from being incredible hunters, many of them have some unique features to distinguish them from other fish in the sea. These sleek critters' scales are more like tooth-shaped spines. Some of the more iconic sharks—like great white sharks—also need to keep moving to make sure enough water flows through their gills. If you're looking to unleash your inner ferocity on the ocean or on the next costume party, then dressing up in one of our shark costumes is a perfect choice.
Shark Costume Adults
When we were kids, the shark was one of the most terrifying creatures in the sea. Why? Well, we saw Jaws when we were young… and that sort of shaped our whole opinion on sharks. To this day, we still can hear the theme song playing whenever we see a shark fin. That movie has become one of our favorite movies, and it is also part of why we've grown up being just a little bit wary of any beach that seems a little TOO perfect. While we do carry some pretty ferocious-looking shark costumes for adults, we sort of prefer sharks that tone it down on the ferocity. Well, we carry some great shark costumes for adults that are the right combination of cozy and fierce. That way, you can be one comfortable fish when you head to your next costume party.
Shark Costume Kids
Now, kids these days? They have a much different experience with sharks. Most teens haven't even heard of the movie Jaws. They also haven't heard of Street Sharks! (Vin Diesel is somewhere, shedding a single tear over that.) They've all been indoctrinated with the ways of Baby Shark. If you're a parent of a young child, then the Baby Shark song probably started playing inside your head. We have a whole selection of licensed Baby Shark costumes! Also, we totally won't judge if you toss the Baby Shark song on your playlist right now. (We secretly like Baby Shark waaaay more than we should.)
And then, there's the lobster. Far from being an apex predator, these crusty crustaceans crawl around on the ground, looking for anything it can munch on. Lobsters don't get quite the love that other critters do, but we think they deserve a little more attention. Did you know that lobsters don't age? It's true! Their genetic material doesn't deteriorate like most animals, so even though a lobster gets older and larger, it doesn't get "old" as humans do. Of course, they end up having another problem after living for many years. They get too big! Lobsters need to molt as they get bigger, but that takes a TON of energy. So if they reach a ripe old age, they can just get too exhausted while attempting to molt and meet their end!
Yep, lobsters are a strange and cool creature. If you're a strange and cool human, then you might want to dress up like one. We carry some lobster costume options that will have you scuttling across the ocean floor. Oh, and no molting necessary to slip into any of these.
Baby Lobster Costume
Few people would consider a lobster cute. (We do, but we're a little weird like that.) Of course, your baby doesn't have that problem. With the help of one of our baby lobster costumes, your little one can turn the crusty critter into a cute creature. Most of our baby costumes are designed for comfort as well as cuteness, and our lobster costumes are no exception!
Lobster Halloween Costume
Our lobster Halloween costumes for adults—how do you know it's for you? Well, that's just something you kind of know. Search your soul. You're either a lobster or you're not. If you look at this strange outfit and feel the odd urge to scuttle and snap your claws, then you're a lobster person. If you look at this kind of costume and you just get a little hungry, then you're probably not ready to be a lobster!
Ever feel like you don't have enough arms? It's kind of an odd question, but it's something we think about way too much—mostly when we're trying to carry groceries inside. Instead of taking a dozen trips, we could just carry all of the bags in at once. Well, that's a problem the octopus doesn't have. Not only because octopuses don't buy groceries, but also because those curious cephalopods have 8 arms, kind of like the spider of the ocean. If you dream of having some extra arms, then it's time for one of our octopus costumes.
Adult Octopus Costume
What's your favorite animal? It's not really a question that people ask when you grow up. It's a question that's reserved for kids. But why? As you get older, you only get a larger view of the world. You get to see even more animals and form more measured opinions. Maybe your favorite animal is the octopus, but no one would know because adults don't think to ask other adults that question. Well, now's your chance! With an adult octopus costume, you can proclaim your love of cephalopods to the world!
Octopus Halloween Costume
Perhaps you're looking for something a little more extravagant? Something that truly makes you feel like an octopus, inside and out. Then how about the sort of octopus costume that gives you extra-long tentacles, perfect for interacting with costume party-goers and trick-or-treaters! Our octopus Halloween costumes are an easy choice for anyone who's trying to up their undersea experience.
Kids Octopus Costume
Kids are always drawn to the strange and unusual. It's why kids tend to love zombie costumes and horror costumes. It's also why some kids don't like normal animals, like cats and dogs. It's those very same kids who end up liking octopuses! This kids octopus costume was designed for all of those kids out there who like weird animals, and it's perfect for their next costume party!
Toddler Octopus Costume
Octopuses are known as curious animals. They like to examine anything that they can get their little tentacles on! Well, toddlers can be the same way. Anyone who's gone through the terrible twos…or the sequel, which we've taken to calling the thorny threes, knows that toddlers get into everything. They're not content sitting around quietly. They need to grab everything and explore to their heart's content. If your child is starting into that phase, then our toddler octopus costume is quite fitting!
The oceans are a big place! They take up over 70% of the Earth's surface, and not every animal living in the water is strange and creepy. Let's change gears to one of the sea's most adorable creatures, the narwhal. The narwhal looks sort of like a magical animal that would be the main character in a fantasy story. Its sleek look and single horn give it a unique appearance! So if you want to feel like the unicorn of the ocean, then one of our narwhal costumes is going to be the perfect choice for you. Check out some of our favorite options below.
Narwhal Halloween Costume
Actually, forget unicorns! If we're being honest…we're not even sure if unicorns are real. We've never seen one in real life, and even though there are plenty of medieval tales about them, we don't take those old stories seriously. Narwhals, on the other hand? We've seen those. They're totally real and we think they're just as magical as a unicorn. This narwhal Halloween costume is for anyone who wants to mix a dose of reality into their fantastic creatures.
Narwhal Costume Kids
There's just something about the narwhal that inspires a sense of child-like wonder in people. Naturally, no one has child-like wonder like a child and it's why so many children are intrigued by the strange creature of the sea. Our narwhal costumes for kids are perfect for any child who loves the narwhal. They come with a whale-like bodysuit, combined with the single horn on top, so your child will be able to indulge in their favorite sea animal for Halloween.
Ever since we watched The Hitchhiker's Guide to the Galaxy, we've always had this sneaking suspicion that dolphins might be smarter than us! It's definitely true that dolphins are the brainiacs (not to be confused with the Brainiac of Superman comics) of the sea, and if you want a smart sea creature costume, then our dolphin costumes are exactly what you've been looking for.
Adult Dolphin Costume
We can admit it. When we were young, we had dreams of being a dolphin when we grew up. It's true, well before we understood the ways of the world and before anyone told us that a human can't turn into a dolphin, we had the crazy dream of being a porpoise with a purpose. Well, our adult dolphin costumes bring you a great look for anyone who has dolphin daydreams.
Kids Dolphin Costume
Dolphins aren't just known for their Einstein-like smarts. They're also known as one of the most playful creatures of the sea. It seems that intelligence and playfulness go hand in hand in the animal kingdom, and we think it goes hand in hand with humans! If you have an intelligent and playful child in your life, then it sounds like dressing up as a dolphin would be a match made in heaven!
Sea Creature Costumes for Adults
We've covered a lot of animals on our list, but we didn't stop there. Our costume designers are dedicated to crafting costumes for everyone, and that's precisely why we have such a large selection of Made By Us exclusives. Many of them are niche outfits, and they're ones you won't find anywhere else. They studied all sorts of different underwater environments to get these sea creature costumes for adults to look just right! If you want something that's a little out of the ordinary, then try just take a look at some of our specialty costumes below—you might just discover the perfect catch!
Seals are basically like the dogs of the sea. They sort of look like dogs, they like to bark, and we bet that they'd enjoy a good game of fetch. If you're a dog-lover and you're looking for a costume that will help you express your love of doggos, then you may want to consider giving one of our seal costumes a try for your ocean-theme!
Jellyfish might be one of the most fascinating creatures in the sea. It looks a little like a mushroom floating around in the ocean. It looks like something out of a surreal Salvador Dali painting! Well, we have a cute jellyfish costume that will help you transform into the surreal creature. It'll have you looking extra cute for your ocean-themed costume party.
Shrimp has become synonymous with the word "small" but shrimp can be quite the tough and hardy critter in the wild. The mantis shrimp is one giant crustacean with a mean punch. They're capable of using their claw to punch with force equivalent of a bullet! This shrimp costume might not help you with your right hook, but it's certainly anything but small and shrimpy!
And now, we have the deadliest creature of the seas…the giant squid. Or at least, if you look at any old hand-drawn pirate map of the seas, the squid looks like a leviathan capable of taking down any ship. Although we haven't really been able to catch too many glimpses of the giant squid, we know it's a majestic creature that could be as long as a football field! If you're mysterious and majestic, then you might want a giant squid costume. Pirates will definitely be wary of you!
