I took a few photos of signs on tanks visible at the back of one of the amphib rooms. They all refer to Pebas Stubfoot Toads, some yellow, some purple, some sexed, some not.
Well spotted Gigit! And well spotted toads too Atelopus species are said to be rather harder to breed and raise than many dart frogs, but I'm sure they will be in good hands at Paignton.
