Inside Swansea’s deadly new zoo exhibit where venom could help cure cancer

Plantasia Tropical Zoo has unveiled its latest exhibit, Vital Venoms and Practical Poisons, bringing some of the animal kingdom’s most feared creatures face-to-face with the public.

But behind the fangs, stings and toxins lies something far more surprising — scientists are now studying these species in the fight against cancer, diabetes and chronic pain.

From fear to frontline science

The new exhibit features eight venomous and poisonous species — each with a story that goes far beyond their bite.

Among them is Lucy the beaded lizard, one of only two venomous lizards in the world. Her venom is already being explored in research into type 2 diabetes.

Brightly coloured poison dart frogs — famous for their toxic skin — are helping inspire powerful new painkillers, while fire-bellied toads are being studied for compounds linked to breast and prostate cancer treatments.

Visitors can also come face-to-face with:

  • A mangrove snake, whose venom could play a role in colon cancer research
  • A Brazilian salmon pink bird-eating tarantula, linked to chronic pain studies
  • An Asian forest scorpion that glows under UV light
  • And even assassin bugs, whose venom is being used to develop eco-friendly insecticides

‘Look closer and be amazed’

Zoo bosses say the aim is to turn fear into fascination — and show how nature’s most dangerous creatures could hold the key to future medicine.

Paul Sheppard, Attraction Manager at Plantasia, said the exhibit is designed to get people thinking differently.

He said: “We’ve taken a familiar part of the zoo and turned it into something completely different.

“This new area invites visitors to look closer, ask questions and discover just how clever nature can be.”

A bold new chapter for the city centre attraction

The exhibit is part of a wider expansion at Plantasia, which has been growing its offering with immersive experiences including its dinosaur-themed Giants of the Past and large-scale escape room challenges.

Cllr Elliott King, Swansea Council cabinet member, said the latest addition is another boost for the popular attraction.

He said: “It’s great that Plantasia has this fantastic new exhibit… I highly recommend a visit.”

More than just a day out

As well as giving visitors a close-up look at some of the world’s most misunderstood animals, the zoo says the exhibit plays a key role in its conservation and education work.

The long-term plan even includes adding a critically endangered species and contributing to international breeding programmes.

And while the creatures inside may look intimidating, the message is clear — they could be helping to save lives.

Mission under way to save 'world's most beautiful' snails

Researchers in Cuba and the UK are working together to reveal the biological secrets of the beautiful but endangered Polymita snail.

Red Wolf, I’m a fan of your silly big ears. I’ve been tracking one via Fahlo recently. She’s evidently had 14 pups, that’s wild!
These guys are a critically endangered species that is native to North Carolina, which is where I live now. They used to be everywhere from New York to Texas but hunting was so bad that they were declared extinct in 1980. They’re the only wolf exclusive to the United States. Thanks to humans’ help they’ve been growing in population again! As of last year there were 293 Red Wolves in human care across the States and 17 in the wild in North Carolina. They’re very good boys and girls. I’d love to go see them someday. 🐺
