David Attenborough Explores the World’s Strangest Cave Creatures - the Troglobites
Sunday, 10 May 2026
Animals that are cave specialists are known as troglobites and can be counted as the most specialist species in the world – one species of angel fish troglobites lives only in two small cave waterfalls in Thailand. To say that they have a precarious grip on survival in this day and age is putting it mildly. Many of these species have lost the use of their eyes altogether as the sun never penetrates their cave dwellings. However, to become troglobitic can take thousands of generations.
This fascinating video from BBC Earth, narrated by Sir David Attenborough looks at troglobites in general – those who have lost the pigment in their skin and also their eyes. However, to compensate for their blindness, creatures like the Texas Blind Salamander has other senses fine-tuned to compensate for their lack of sight. Take a look at this video – and discover more about the strange cave-dwelling species, who somehow manage to survive despite the odds being massively stacked against them.
