Who needs make-believe monsters when we have 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!

2. Stargazer

This beauty sits just beneath the sand with only its eyes and sharp teeth poking out, ready to ambush its prey. It 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 attract their prey using a light at the end of their long dorsal spine that flashes on and off above their head. Its teeth are so big, the viperfish can’t even close its mouth.

5. Lamprey

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

6. Scorpion fish

This camouflage expert has skin flaps that help it blend in 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 its large mouth allows it to swallow prey whole.

7. Red-toothed trigger fish

This little fish looks dressed up for a Halloween party with its bright red ‘fangs’. Feeding on plankton and sponges, the red-toothed triggerfish is all bark and no bite.

8. Bobbit worm

This worm may look fairly harmless waiting in the sand with only a small amount of its body on show. But hidden beneath is the rest of its body which can grow up to 10ft long. The speed at which the worm attacks and the power of its mouth can snap its prey clean in two. It then injects a toxin to stun or kill its prey.
