Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept in a 550-liter reinforced glass tank located at Site-. Saltwater in the tank should be kept between 10°C and 14°C at all times. There should be no more than twenty instances present at any time. Any type of crude oil or crude oil-based product is prohibited within 50m of SCP-XXXX's containment area to limit the chances of SCP-XXXX reproducing as much as possible. Additionally, all waters containing oil rigs or those used for transport of crude oil or crude oil-based products should be monitored for any spills and instances of SCP-XXXX. When found, Foundation personnel should intervene to prevent further reproduction of SCP-XXXX and to contain or terminate all new instances as soon as possible. Class A amnestics should be utilized for any witnesses of SCP-XXXX's anomalous properties in the case of such an event.
A deceased instance of SCP-XXXX
Description: SCP-XXXX appears to be a group of blue jellyfish (Cyanea lamarckii), each measuring approximately 20cm in length with little margin. Instances of SCP-XXXX reproduce via fragmentation at an exceptionally high rate and are triggered to do so when consuming crude oil or any refined crude oil products (such as petroleum or gasoline). Instances of SCP-XXXX will begin to multiply approximately once every 25 seconds after consuming oil and will continue to do so as long as they frequently take in this sustenance.
SCP-XXXX has the chance to manifest in contaminated marine waters shortly after a substantial amount of crude oil or refined oil is spilled onto the surface. SCP-XXXX has only responded to two oil spills, both with spillage above 200,000 tonnes. SCP-XXXX does not manifest in the event of 'natural' oil spills, such as oil seeps in the seafloor. Instances have not been found in any circumstances other than manifestation at oil spills.
Discovery: SCP-XXXX first appeared on ██/01/1991 in the Persian Gulf in reaction to between 270,000 and 820,000 tonnes of petroleum being spilled into the waters. Approximately ███,000,000 SCP-XXXX instances were recorded to have manifested or been produced from the anomaly's oil consumption and resulting multiplication. Foundation personnel contained thirty instances (though fifteen were later declared unnecessary to keep and therefore terminated), while the remaining were terminated immediately after. Surveillance of the Persian Gulf and surrounding waters showed no signs of new instances after the incident was brought under control.
Incident XXXX-01: On ██/04/2010, the second SCP-XXXX incident occurred in the Gulf of Mexico, shortly after an explosion and spill occurred involving the offshore drilling rig "Deepwater Horizon". These instances continued to consume oil and multiply until ██/07/2010, two days after the underwater well was sealed. Approximately ██,███,000 instances of SCP-XXXX resulted from the two-month-long spillage event.
Incident XXXX-01 was the first recorded time the anomaly was interacted with, as emergency personnel sent to douse flames and evacuate workers from the capsizing rig came within close range of the instances. These instances supposedly attacked some individuals who attempted to touch or pick up instances while they consumed oil. The reason for this behavior is currently unknown.
Interview Log XXXX-01
Interviewed: ████████ ██████, emergency responder deployed during Incident XXXX-01
Interviewer: Dr. █████████ Durham, Head Researcher
Foreword: ████████ ██████ Discusses his interaction with an SCP-XXXX instance and the causes of the burns and lacerations spanning from his hand to his forearm. This interview took place shortly after Incident XXXX-01.
<Begin Log>
Durham: Mr. ██████, describe what you witnessed around the "Deepwater Horizon" oil rig the day of its collapse?
██████: There were these… jellyfish in the water, and loads of 'em. Which was weird since jellies don't really come to the surface unless they're dead, I think. And these were alive. ████ said we should grab one, which I told him was stupid. But he went and fished one up with a net anyway.
Durham: What did you two do with this jellyfish you took out of the water?
██████: We didn't do anything. It did. Grabbed me with its tentacles and gave me this damned burn. (raises his bandaged arm slightly, wincing.)
Durham: Unprovoked?
██████: Yeah. Then the little shit flung itself back into the water. The boys helped me get off the deck but ████ kept his eyes on that thing. He said it fell right into a patch of oil, and when it resurfaced was, like… eating it? Or soaking it up, or something. (he chuckles.) He described 'em as a little cleaning crew. Mother Nature's janitors, he said.
Durham: Did these jellyfish cause you or your group any trouble for the remainder of your job?
██████: Nah. I went with the medic crew that came for the rig workers. Later ████ said those jellies did whatever they were doin' without botherin' the crew for the rest of the time.<End Log>
Closing Statement: ██████ described SCP-XXXX through his recounting as hostile when provoked but otherwise disinterested. Class A amnestics were later utilized for him, his crew, and all other individuals who witnessed SCP-XXXX instances during the incident. Further testing of SCP-XXXX's behavior and reactions to outside contact is pending approval.
