Who needs make-believe monsters this Halloween when we have our real life scary sea creatures?

1. Angler fish

The charming good looks of the anglerfish remain hidden in the dark, as it uses a bright lure to bring unassuming prey up close to its sharp teeth. The male black devil anglers have a strange clingy side - after finding a female, they latch on and don’t let go!

Watch your step! This beauty sits just beneath the sand with only its eyes and sharp teeth poking out ready to ambush its prey. This guy packs a punch with venomous spines and gives electric shocks to unwary prey.

3. Vampire squid

In the dark depths of the sea, this red eyed squid has webbed arms that look like the jet black cape of a vampire when raised in defence! Using jet propulsion to ‘fly’ through the water, it expels a sticky cloud of bioluminescent mucus from the tips of its arms.

4. Viper fish

These deep sea fish remain still in the water, and attract their prey using a natural light at the end of their long dorsal spine that flashes on and off above their head. With teeth so big, the viperfish can’t even close its mouth!

5. Lamprey

This prehistoric, parasitic fish detects vibrations in the water and latches onto its prey - feeding on flesh or sucking blood. This is a protected species and their return to UK rivers is a symbol of better water quality.

6. Scorpionfish

This camouflage expert has skin flaps that help it blend perfectly with its surroundings, aiding its strategy as a ‘sit and wait’ predator. It’s one of the most poisonous fish in the world, and their large mouth allows them to swallow their prey whole.

7. Red-toothed triggerfish


This cute little fish looks like he’s dressed up for a Halloween party with those bright red ‘fangs’. Feeding on plankton and sponges this peaceful fish is all bark and no bite.

8. Bobbit worm

This worm may look fairly harmless whilst it waits in the sand with only a small amount of its body on show, but hidden beneath it can grow up to 10 feet long! The speed at which this guy attacks, and the power of its mouth can snap is prey clean in two. It then injects a toxin to stun or kill its prey.
