Halloween is the time of year to celebrate all of the interesting, weird and creepy beings from around the world. The ocean is particularly abundant in unique-looking organisms. Ranging from the deep sea to shallow waters, the ocean is full of creepy creatures with some amazing skills – and here at Free the Ocean, we love them all. That’s why, this Halloween, we gathered some of our favorite eerie ocean animals to celebrate this spook-tacular holiday.

If you are afraid of sharp objects, stay away from the sawfish. Their saw helps them detect electric pulses produced by their prey.

 It’s essentially a giant spider that lives in the ocean, who wouldn’t be afraid?! But all jokes aside, the giant Japanese spider crab is awesome. With a leg span able to reach 15 feet, these crabs are some of the world’s largest crustaceans.

This invertebrate makes our list due to its coloring. Divided flatworms can grow over 2 inches in length! They may be small but the award for greatest Halloween spirit goes to this divided flatworm.

Octopuses are notoriously good at hide-and-go-seek. Their camouflage allows them to change color and texture to hide from any impending danger. You may never know if an octopus is lurking in the depths!

This terrifying creature has an overbite even the best orthodontist couldn’t fix! Though its large mouth looks a little off-putting, the enlarged jaw allows the gulper eel to consume a wide-variety of prey ranging in size – from a small snack to a large feast.

Frogfish look a lot like a zombie from The Walking Dead. They may look slightly scary but are accomplished walkers. Frogfish are well known for their use of pelvic and pectoral fins to launch themselves across the ocean floor.

These fascinating-looking fish are known to participate in some very interesting behavior when defending neighboring territories – I wouldn’t trick-or-treat near their house.
