The African Graboids are much bigger than their American relatives, being about 40-50 feet in length. They have far more prominent body spines, in skeletal-looking ridges on their bodies, and they possess multiple sets of sharp-toothed jaws. Their most prominent difference, however, is that their tongue-like tentacles are able to detach from the body and function as independent organisms. They lay their eggs in great numbers in nesting caves, which are guarded by the African Ass-Blaster.
In the film
Early on in the movie, two scientists discover the the fossilized remains of one, but are later eaten by a live specimen while they are in the shower.
Another specimen later attacks the townspeople in a South African village, but is tricked into attacking a jeep with lit fuel and is blown up.
A large individual, dubbed the "Queen Bitch" later attacks Burt and co. in an attempt to retrieve its last remaining egg. However, they lured it into a trap, using the egg as bait, and killed it by directing lightning, causing it to explode.
- Their appearance is much more similar to deep-sea worms as opposed to the crustacean-like appearance of the American Graboid.
- They are implied to be eusocial, with one large graboid being referred to as a 'queen'.
