Description: SCP-075 has the shape of a snail, except the muscular 'foot' resembles a six-fingered hand. It is 20 cm in length, 13 in width, and has a mass of ~860 kg. This exceptional density is yet to be understood.
In its acceptable state, SCP-075 is almost completely dry. Desiccation is the only known means of paralysis.
When not desiccated, SCP-075 moves at an alarming speed for its size. It adopts the behavior of a predator, jumping at and drenching its prey in an acidic solution seemingly secreted from pores on the muscular 'foot'. No currently available acid can match the power of SCP-075's secretions. Given SCP-075's threatening level when not disabled, this acid may not be harvested. Therefore, no material resisting to its corrosive power has been found yet.
Addendum [SCP-075f]: All tests meant to harvest SCP-075's acid must be approved and supervised by all Level-4 personnel of the site. However, approval of said personnel can not override the interdiction to introduce any liquid solution near SCP-075, including its acid.
Addendum [SCP-075g]: A cup of acid from SCP-075 was successfully harvested by using SCP-294. Testing is underway to determine what, if any, known substance is immune to the acid. Testing is also underway to determine why the cup provided by SCP-294 is inherently immune to the acid's effects.
