SCP-695-A

## **`DESCRIPTION`**

SCP-695-A appears to be a form of hermaphroditic parasitic eel. SCP-695-A has a multiple-stage life cycle that uses human beings as its primary host. Investigation has shown that SCP-695-A may be the result of genetic tampering. SCP-695-A is capable of sustained survival outside of a host, but will seek out a host whenever possible, appearing to rely primarily on smell and electromagnetic sensitivity.

Juvenile SCP-695-A are between 3 and 5 cm (1.2 and 2 in) long, with an average diameter of 0.5 cm (0.2 in), and resemble the adult form, but with fully translucent skin and bones. Adult SCP-695-A are between 10 and 15 cm (3.9 and 5.9 in) in length with a diameter of 2 cm (0.8 in). Adults have thin, angular heads with several needle-like teeth, and flat eyes in line with the head. They have several hook-like fins down the length of their body, and can use these for both aquatic and land-based movement, as well as anchoring inside the body.

SCP-695-A has a set of six glands along the spine, capable of emitting several enzymes and complex molecular compounds that mimic neurochemical signals. These chemicals have a marked effect on the human nervous system, and are capable of blocking and replacing conscious nerve impulses. The correct combination and dosage of these chemicals is still under investigation, but initial tests have shown that these chemicals can “short” and “redirect” action. (Example: Subjects will make a conscious effort to raise their hands, but instead will stand up). These chemicals metabolize within ten minutes without constant injection, and are untraceable by modern medical equipment.

SCP-695-A was initially recovered from Katagami, Japan, after reports of an outbreak of “worms” reached the local media. The primary colony of SCP-695-A was found in Lake Tazawa and were observed being able to easily thrive in freshwater. It appeared that the colony was attempting to migrate into city plumbing and sewage systems, but was prevented due to the topography of the lake. A total of 27 SCP-695-A instances, 4 male hosts, and 1 female host were recovered for testing, with the rest destroyed.

Juvenile SCP-695-A will attempt to enter male human hosts when they are present in or around SCP-695-A infested waters. SCP-695-A will enter the body via the mouth, nose, anus or urethra. Once inside the body, SCP-695-A will infest the nervous and reproductive systems and begin gestation into its adult stage. This process typically takes between two to three weeks, and coincides with the compromising of the nervous system.

Infested subjects will begin to experience twitching, burning, intense thirst, light sensitivity, auditory and visual hallucinations, and a steady increase in aggression and libido. SCP-695-A, after reaching maturity, will begin producing offspring within the body, with eggs migrating to settle in the testicles after being laid. When an SCP-695-A host encounters a human female, SCP-695-A will begin to exude several chemical compounds directly to the host's nervous system and bloodstream. Hosts will experience a massive and sudden increase in both aggression and libido, which most often results in the violent, {REDACTED} assault of the female. Once coitus has begun, SCP-965-A will release another compound into the host's body, which will trigger acute perspiration, through which the chemical is expelled via the host's pores. Contact with a human female's skin will cause an immediate aphrodisiac effect, inducing an intense arousal in the victim. This is thought to reduce struggle and ensure a greater chance of survival for the offspring. Upon the host reaching {REDACTED}, their climax will cause a release of SCP-695-A eggs into the female subject. Hosts will typically release 2-3 liters of eggs before breeding ceases, with each egg measuring approximately 0.64 cm (0.25 in) in diameter. This accounts for between 14,918 and 22,377 eggs per breeding.

SCP-695-A eggs entering the female host will migrate to the reproductive system. There, they will adhere and begin to gestate, hatching in 48-72 hours. Larval SCP-695-A appear as long, thread-like worms between 4 and 8 cm (1.6 and 3.15 in) in length, and may be visible in vaginal secretions. SCP-695-A larvae will reach the juvenile stage after 72 hours, with progressive swelling and mild discomfort in the abdominal area due to the physical size increase of the SCP-695-A. SCP-695-A will sap nutrients from the female host much in the same way as a human infant; with thin, tendril-like barbs facilitating the same function as an umbilical cord. The size increase of the female's stomach will be proportional to the approximate size of a female pregnant with triplets to quintuplets.

After 72 hours, juvenile SCP-695 will begin exiting the body en masse. SCP-695-A will leave via the vaginal opening, before propelling themselves on their hook fins to any nearby body of water. SCP-695-A are extremely resilient in all life stages, and are capable of indefinite survival in a multitude of environments. Extreme heat seems effective in sterilizing both hosts and SCP-695-A. Outside of a host, juvenile instances of SCP-695-A are able to live seemingly indefinitely, with no observed signs of aging or maturation to date. However, once reaching maturity inside a male host, SCP-695-A instances live for no longer than 120 days (approximately 4 months).

Male hosts will continue to breed at any opportunity, thinking of little else, and are able to produce SCP-695-A offspring in every instance. If a female has sex with another male individual while infected, or even after giving birth, should a few unmatured larvae remain in their vaginal excretions, there is a chance that they might pass the infection to their partner, which will result in the larva entering the juvenile and then adult stage within three weeks. Even after the female gives birth and after the male's adult instance of SCP-695-A reaches the end of its life cycle, the increase in libido remains permanent in both subjects. Although the male will regain their autonomy, they will retain all memories of their actions, causing significant emotional distress for all parties. In a small group however, both male and female might seek reinfection, claiming that their newly increased {REDACTED} without the presence of the parasite makes them feel "empty". It is unknown if this is caused from the trauma of the experience or an induced reaction by SCP-695-A. Although most are unable to locate additional instances, some victims have been observed, prior to containment, following freshly birthed instances back to bodies of water.
