Promachoteuthis Sulcus Facts
- Don’t let the nightmarish appearance of the Promachoteuthis Sulcus frighten you. For those fearful of such creatures, one fact stands out. This terrifying looking denizen of the deep remains a physically tiny creature.
- This bizarre animal actually currently represents the rarest known species of squid on earth. That’s because the unique individual pictured here remains the only specimen that ever found.
- Therefore, extremely little definitive information exists concerning the Promachoteuthis Sulcus at this time. Researchers have not yet even determined whether the lone individual of this cephalopod was an adult or infant, or male or female.
- It also remains famous for the unique characteristic of possessing human-type teeth. However, these are not actually teeth at all. Rather, they represent lips folded over the razor-sharp beak.
Promachoteuthis Sulcus Physical Description
For obvious reasons, researchers cannot provide even estimates of the size of mature examples of the Promachoteuthis Sulcus at this time. However, the lone diminutive creature examined so far measured a scant 1 in (2.5 cm) in total length.
Physical characteristics of the species also exist only in relation to the one specimen found so far. Firstly, each tentacle measures wider at the base than at the tip. Secondly, three rows of suckers appear present on each tentacle. These also show smaller than those on the body.

Promachotuethis Sulcus Distribution, Habitat, and Ecology
The Promachoteuthis Sulcus was captured entirely accidentally by a research vessel in the vicinity of Tristan da Cunha. This sits in the southern Atlantic Ocean, 1,500 mi (2,400 km) from South Africa, in Africa.
Quite unfortunately, the appearance of the animal needlessly inspires fear in many. Despite its obviously rather fearsome appearance, the lone specimen discovered to date posed absolutely no threat to humans.
This incredible ocean dweller does not even possess a common name as of the time of the writing of this article. The single example discovered to date lived at a great depth of roughly 6,560 ft (2,000 m).
Sadly, but understandably, experts know nothing about its habits, lifespan, or diet. However, it can be assumed that it consumes a variety of small fish and crustaceans. This would be similar to other cephalopods.
