Penis snake

Despite the name, this phallic-looking creature is neither a snake… nor a penis. It’s actually a type of caecilian: a limbless amphibian that bears more than a passing resemblance to a certain part of the male anatomy. So naturally, this creature also goes by names such as the ‘manaconda’ or ‘floppy snake’ – its Latin designation is Atretochoana eiselti.
Little is known about the species, and from its discovery in the late 1800s to its rediscovery in 2011 from the same region, there were only two preserved specimens. It’s the second-largest lungless tetrapod, breathing instead through its skin, and is the largest-known caecilian, growing up to 81cm in length. It is thought they can live between 5 to 10 years.
Unlike most caecilians, which are burrowers, most scientists agree that the penis snake is actually aquatic, like other lung-less tetrapods. It has poor eyesight – their eyes are barely visible under the skin – but has a keen sense of smell, which it uses to navigate. This combination is ideal, given they tend to live in Amazonian rivers where visibility is poor.
