'World's most beautiful snail' is at risk: What UK scientists are doing to save the species
The snails, known as Polymita, are endemic to Eastern Cuba and feature shells with vibrant colours and interesting patterns.
The shells come in many different colours, from yellow and pink to red and black.
But these patterned shells have become popular among collectors and poachers who sell the shells to tourists or trade them overseas.
Despite it being illegal to remove these snails from their native habitat under the Convention on International Trade in Endangered Species, it has not stopped the international trade of the shells.
Researchers from London Zoo and the University of Nottingham have travelled to Cuba to meet local scientists to assess the conservation status of the six vulnerable painted snails, as well as better understand their evolution and how to breed them.
The Polymita sulphurosa snail, which has a lime green, blue and yellow shell, is considered the most endangered of the species and is at risk of extinction.
There are believed to be fewer than 30,000 remaining in the coastal forests of Cuba, which is the only place they live.
University of Nottingham's Professor of Evolutionary Genetics Angus Davison is hoping to get the species put on the International Union for Conservation of Nature's red list.
"It's all part of a global effort to be proactive about the species conservation," Professor Davison said.
"One species of painted snail is the most threatened – it was touch and go, but we were very fortunate to finally find them.'
The experts also hope to establish a conservation breeding programme in a lab to help save the invertebrate from extinction.
London Zoo's Dave Clarke said the Cuban painted snails were "incredible" and he was very keen to conserve the species.
"Finally finding a population of the rarest species in a remote location was a relief, however we also saw evidence of fresh habitat destruction," he said.
"We hope these exceptional snails can be successfully reared in the lab to learn more about them and provide a failsafe against the threats in the wild.'

London Zoo's penguins and giant tortoises hit the scales on weigh-in day
What we've learnt from today's weigh-inpublished at 12:59 British Summer Time 12:59 BST Image source, EPA/Shutterstock With the big result announced, that's our portion of the weigh-in concluded. We only really got a small glimpse at the massive operation that goes on here in Regent's Park, with over 10,000 animals on site. From lemurs to giant tortoises, we've seen how the keepers deal with the challenge of tempting some of the zoo's residents onto the scales. (Spoiler: it usually involves snacks.) The rest of the Zoo's animals will be weighed over the next week, before results are shared with conservation organisations across the world. Before I head off to pet an alpaca, a huge thanks to London Zoo's team who've shared their work with us this morning. Thanks for reading.

Giant Galapagos tortoise aged 30 and the world's largest rodents among animals in London Zoo's annual weigh-in
A 30-year-old giant Galapagos tortoise named Priscilla and a pair of the world's largest rodents were among more than 10,000 animals at London Zoo's annual weigh-in. London Zoo is home to 4,000 different animal species that are all weighed and measured on a regular basis to monitor their health, development and identify pregnancies. Zookeepers use different training methods or techniques to get individual animals to step on to the scales - Priscilla was lured onto a board scale with a lettuce snack. A pair of capybaras, Humboldt penguins, and a ring-tailed lemur troop were also among the animals to step on the scales. Tint Darwin's frogs weighed in as one of the Zoo's smallest creatures, measuring just two centimetres in length, and under two grams in weight. London Zoo's animal operations manager Daniel Simmonds said: 'The London Zoo Annual Weigh In is not just about numbers on a scale; regular weigh-ins help zookeepers track the health of our animals - including the capybaras, tortoises, and penguins - and genuinely help us manage the care of these animals, who play a vital role in our global conservation efforts.' Many of the zoo's animals are trained to perch on a scale while zookeepers note down their measurements. Meanwhile, for some, scales may be placed in doorways or disguised in their habitats, meaning the animal can be weighed without realising. The zoo says that their weigh-in is an opportunity to ensure the information recorded for each individual is up-to-date and accurate. Each measurement is added to the Zoological Information Management System (ZIMS), a database shared with animal carers and conservationists all over the world. This helps experts to compare important information on thousands of endangered species. Daniel added: 'Our animals here at London Zoo receive world-class care - and a huge part of this is our meticulous planning of their diets. 'Our zoo-tritionist ensures every animal is getting the nutrients they need, while our keepers devise ways to feed the animals that spark all of their natural instincts - keeping them fit and challenged.'

London Zoo begins its annual animal weigh-in
It's that time of year again, when keepers at London Zoo weigh and measure hundreds of animals as part of a yearly of the animals' measurements are recorded in a database called the Zoological Information Management System. It helps zookeepers all over the planet compare important information on thousands of endangered with so many animals, it's not always an easy task to carry out! Let's take a closer look at how it all went. Every mammal, bird, reptile, fish and invertebrate across the zoo is weighed and measured. This capybara needed some tasty treats to be convinced to step onto the scales! These cheeky Humboldt penguins couldn't wait to get on the scales! The penguins are native to the rocky coastal shores of Peru and Chile in South America and are listed as vulnerable to extinction by the International Union for the Conservation of Nature (IUCN). Normal kitchen weighing scale were used to measure this giant hooded katydid. Did you know these impressive insects are not only known for their large size - but they are also able to camouflage themselves as leaves, which helps them hide from potential predators. Animals of all ages and sizes were measured. Priscilla is London Zoo's 30-year-old giant Galapagos tortoise. They are the largest living species of tortoise in the world, and can weigh more than 400kg and survive without food or water for over a year! London Zoo's animals, such as this Vietnamese land snail, are weighed and measured on a regular basis. This helps keepers monitor their health, wellbeing and development. And finally, check out these playful ring-tailed lemurs who look like they're enjoying the attention and having a lot of fun! These primates live in troops of up to 30 individuals and are known for being very social and vocal animals.
