事实

A studied snake had eaten a caecilian that was larger than the snake was long in relation to its own size, which was unusual because an earlier study had suggested it eats smaller prey.1

Its scientific name, aterrima, means "blackest", which fits its dark, glossy body.1

It is a burrowing snake, so it spends much of its time underground.1
