Spot some of the scariest creatures in the ocean this 'Hallow-marine' as The Sea LifeLondon Aquarium puts the spotlight on some "Bogey-fish" of the deep. Guests should keep their eyes peeled for spooky images dotted on displays around the attraction revealing where these elusive bogey-fish dwell. Look out for the sneakiest, the Devil's Scorpionfish, which ambushes unsuspecting prey with it's gaping mouth.

Or try to spot the deadliest, including the Lionfish and the Moray eel, which has a second set of jaws ready to tuck into prey. Or how about the weirdest, like the alien-looking Longhorn Cowfish which secretes deadly, toxic mucus into the water when it dies and the Blind Cave fish which has no eyes! Plus there will be themed talks and feeds throughout the week.

On Halloween day itself the Fish Witch will be making a special appearance.  The scaly, green marine crone only comes out on Halloween to cook up a cauldron full of spooky fun and those brave enough to come along in fancy dress on the day will also receive a tasty free treat!*

There's also an entire ocean to explore, including rare giant Green Sea turtles, tropical fish, rays, crabs and jellyfish – and for the intrepid, special VIP experiences like a Shark Feed, Turtle Feed and Snorkelling with Sharks Experience.
