VISITORS are being invited to enjoy an underwater scare adventure at Deep Sea World this Halloween weekend.

There will be Halloween-themed trails, fun activities for kids and even spooky scuba divers on Saturday and Sunday.

Any young warlocks or witches who arrive in full fancy dress will get in free when accompanied by a full paying adult on Friday, Saturday and Sunday.

The giant 4.5 million litre Underwater Safari display will also be the venue for the sand tiger shark feed at 1pm on Saturday.

Deep Sea World’s Kelsey Gillies said, “There will be a spooky trail throughout the aquarium to hunt down letters to make up the name of one of our fiercest animals!

“Anyone who succeeds in finding all the letters of the name and marking them on their Halloween themed map will have the choice of a trick or a treat to take part in at reception.

“Also don’t miss the new USS Apagon display which is home to the most venomous fish in the sea, our scary looking stonefish!” Located beneath the world-famous Forth Rail Bridge, Deep Sea World is Scotland’s national aquarium.

With more than 40 naturally-themed displays home to over 2,000 creatures - ranging from seals and seahorses to stingrays and sand tiger sharks – Scotland’s national aquarium provides an incredible voyage of discovery through the planet’s rivers, lakes and oceans.

From lochs and rocky shores to African lakes, South American rainforests and beautiful coral reefs there’s so much to explore.

At the aquarium’s heart is the incredible 4.5 million litre Underwater Safari is home to one of Europe’s largest collections of sharks – including three-metre-long sand tiger sharks - as well as hundreds of other marine creatures including stingrays, lobsters and crabs.
