An immature SCP-2977-1 instance. Estimated current depth is 1.7 km.

Item #: SCP-2977

Object Class: Euclid

Special Containment Procedures: Due to the unpredictability of the emergence of SCP-2977-2, SCP-2977 has been publicly designated as a critically endangered species and provided protection under the multilateral CITES treaty. Non-anomalous research data may be considered for public release at the discretion of the Lead Researcher.

Mobile Task Force Upsilon-7 ("The Glass Jar”) are to monitor international conservation groups for descriptions matching SCP-2977-1. MTF ϒ-7 are to investigate possible instances, locate SCP-2977-2 using chemical pheromone tracking and ground-penetrating radar, and convert affected areas into Provisional Sites under the guise of preservation efforts.1 SCP-2977-2 must be located before full containment is enacted.

Due to the extreme rarity of both SCP-2977-1 and SCP-2977-2, future excavation attempts must be approved by both the O5 Council and the current coordinator of Project Longfellow.

Description: SCP-2977 are a species of eusocial insect of the family Formicidae, commonly known as ants. SCP-2977 members are black in color and reach between 13 mm and 20 mm in length depending on caste. SCP-2977 are externally distinguishable from other Formicidae by their limited reproduction cycle and the characteristic "rainbow" or "bullseye" pattern of debris surrounding their colonies. SCP-2977 also cultivate unusual food species in underground reservoirs in a pattern of agriculture-like mutualism, including Amblyopsidae (Blind cave fish) and tardigrades.

SCP-2977 colonies, designated SCP-2977-1, expand almost directly downward to extreme depths, rarely exceeding 1.5 m in diameter below the surface. SCP-2977-1 are known to extend below 15 km, the maximum depth currently attainable by Foundation technology. The concentric circle pattern of debris surrounding each SCP-2977-1 is created when SCP-2977 members bring excavated material from the deepest point in their colony to the surface, with deeper minerals forming new rings as older debris are pushed outward.

SCP-2977-1 are considered "mature" when they reach an estimated final depth of ██ km and cease producing new debris. (A summary of minerals surrounding a "mature" instance is available in Addendum 2977-1.) Mature colonies produce nuptial flights of male and fertile queen SCP-2977 members in order to produce new SCP-2977-1. This occurrence is extremely infrequent, and has only been observed 16 times across all Sites since initial containment in 1914.

SCP-2977 instances have not displayed digging capabilities superior to those of non-anomalous Formicidae. Based on observations of expanding debris patterns around multiple SCP-2977-1 over time, it is estimated that the time required for a new SCP-2977-1 instance to reach a “mature” depth is ███ years.

SCP-2977-1 are always found in close proximity to a “source” colony, designated SCP-2977-2. SCP-2977-2 emerge sporadically in areas of high volcanic and tectonic activity, primarily in the Pacific “Ring of Fire”. It is believed that SCP-2977-2 originate at an unknown depth and expand upwards until they break the surface, leaving only entry tunnels visible.

Unlike typical SCP-2977 queens, queens emerging from SCP-2977-2 are wingless and reproduce by asexual parthenogenesis. SCP-2977-2 queens also display significant genetic aberrations from SCP-2977-1-produced queens. (Genetic analysis results are available in Document 2977-2.)
