Choke Worm (Suffocatus vermiformis)

The Choke Worm (Suffocatus vermiformis), a newly identified species of toxic worm, was first discovered in 1985 following a meteorite event in southern Florida, USA. This event is believed to be indirectly linked to the cosmic anomaly known as The Tear which appeared in our solar system in 1945. Since their appearance, Choke Worms have become a common species in the southern and southwestern regions of the United States.


The genus Suffocatus is derived from the Latin suffocare, meaning “to choke”, which references the notable method in which these worms incapacitate their prey. The species epithet vermiformis comes from Latin vermis, “worm”, and formis, “shape”, reflecting the worm’s morphology.


Choke Worms are characterized by their elongated, vermiform body and their ability to produce and eject a potent toxin in a viscous slime form. They tend to inhabit areas with dense foliage where they can hang from trees or infiltrate structures and attach themselves to ceilings. Visually, they are identified by their dark, slick appearance, and the slime trails they leave, which is a tell-tale sign of their presence.

Physiology and Behavior

The primary defense and hunting mechanism of the Choke Worm is the secretion of a highly poisonous slime. Upon contact with a potential threat or prey, this slime rapidly induces anaphylactic-like swelling in the mucous membranes, particularly in the throat, leading to suffocation if not treated immediately. Effective countermeasures include prompt administration of strong antihistamines, which have been shown to nullify the toxic effects when administered soon after exposure.

Natural predators of the Choke Worm have not been identified, making their population control difficult and leading to their classification as an invasive species.

Habitat and Distribution

Since their appearance after the meteorite impact at the vicinity of The Tear anomaly, Choke Worms have become prevalent throughout the southern states of the USA. Their tendency to thrive in warm and moist environments has favored their propagation in these areas.

Life Cycle

The life cycle of the Choke Worm (Suffocatus vermiformis) remains incompletely understood due to their relatively recent discovery and the challenges posed by their toxic nature. Initial observations, primarily by researchers at the Institute of Extraterrestrial Biology and Epidemiology (IEBE), suggest that Choke Worms have a quite resilient life cycle.

Reproduction: Choke Worms are thought to be hermaphroditic, possessing both male and female reproductive organs. Due to the limited observations of their mating behaviors, it is currently unknown whether they engage in cross-fertilization or self-fertilization. Researchers have observed egg-like structures believed to be associated with their reproductive process; however, the exact mode of egg laying and incubation remains under investigation.

Development: The development period from egg to a fully grown adult is yet to be accurately determined. Early accounts from the IEBE study instances of near adult-sized Choke Worms discovered within weeks of reported meteorite fall which suggests a rapid growth rate.

Metamorphosis: There is no evidence of a metamorphic cycle in Choke Worms. They seem to retain a similar morphology throughout their life stages, gradually growing in size until they reach adulthood.

Lifespan: Due to the limited time frame since their discovery, the lifespan of the Choke Worm has yet to be established. Studies of related terrestrial worm species suggest a potential lifespan range from 5 to 10 years, subject to environmental conditions and predation, though in the absence of natural predators, Choke Worms may surpass this estimate.

Behavioral Development: Mature Choke Worms have demonstrated a distinct behavior of hanging from tree branches or ceilings, which is presumed to assist in ambushing prey. It is unknown at what stage of development this behavior is adopted, but it appears to be intrinsic to the species.

Further research by the IEBE continues to clarify these details. The institute has put out calls for safe and humane collection of specimens to aid in gaining a more comprehensive understanding of the Choke Worm’s life cycle and reproductive habits.

Human Interaction and Impact

The removal of Choke Worms from affected areas has proved extremely challenging and costly due to both their climbing abilities and toxic defense mechanisms. Populations living in these regions are advised to exercise extreme caution when dealing with or in proximity to these creatures. Known infestations have led to significant economic impacts, particularly in agricultural communities, and have posed serious public health concerns.

Research and Studies

The Choke Worm remains a subject of intense study. Teams of scientists from the Institute of Extraterrestrial Biology and Epidemiology (IEBE) have been at the forefront of researching the species. According to IEBE’s lead researcher Dr. Howard Franklin (1988), “Understanding the Choke Worm’s biological structure and the mechanisms behind its toxic secretion is imperative for developing effective containment and eradication methods.” Ongoing studies aim to further understand their physiology, reproductive habits, and potential weaknesses.


Given the hazardous nature of the Choke Worm and its status as an invasive species, conservation efforts are currently non-existent. Instead, focus has been placed on control, containment, and, if possible, eradication. Public advisories and education campaigns continue to be critical tools in preventing human casualties and limiting the spread of these creatures.
