Lurker (ラーカー Rākā ) is a file that can be found in Resident Evil: The Darkside Chronicles.
A B.O.W. born from early experiments with the T-Virus made from an amphibian frog base. Their eyes and ears have devolved greatly in this form, but their ability to sense prey has evolved to an almost supernatural level. Their tongues have become strong enough to actually impale a human target with little effort. Their degestive systems have also developed to the point where they can swallow a human whole. Although their contain formidable offensive properties, the reason the Lurkers were not able to be employed as actual B.O.W.s is because of the gaping lack of intelligence.
