Item #: SCP-3157

Object Class: Euclid

Special Containment Procedure: SCP-3157 is to be kept on site ██. If staff notice anything unusual about the containment tank they must report to the administrator immediately and the SCP will be moved to site ██ - 2. SCP-3157 is to be kept in a 3 mi (4.82 km)3 tank with reinforced 4 ft thick glass. There is exactly 29730162980571.43 gal of water in the tank. There should be no escape route from the tank other than the large water jet on the east side of the tank. But this exit is monitored by underwater security cameras and bars.
Only class 5 personnel are permitted to enter 3157’s tank. They must take a spear gun coated with tranquilizer venom, they must also carry with them water vibration detection software and night vision goggles to see in the non lighted water.

Description: Although its species is unknown SCP-3157 has a similar appearance to a manta ray and is aquatic. It is approximately 1.34 mi (2.15 km) long and 1.46 mi (2.34 km) wide. SCP-3157 is normally very calm and not aggressive to humans. However, SCP-3157 occasionally have aggressive bursts. During these times it will ram itself into the glass and produce a deep bellow. These time periods usually last somewhere from 15 to 20 minutes. If anything unusual happens within these time spans staff must report it to dr. █████, the animals biologist. The SCP appears to have no teeth. SCP-3157 has appeared to have grown retractable teeth that were not here when the animal was captured █/█/██. Dr.█████ does not have an explanation for this but he says if staff notice any other growth happening to the animal to report it to him immediately.
