Here we see some rare examples of the species Homo Patternenvelopus.
Notice the older specimens are shy, and avoid direct eye contact (a sign of challenge). The young, however, are bolder, unless they venture too far from the mother. They also have not yet developed the distinctive hand coverings of the adults.
Homo Patternenvelopus breeds fissiparously, and the sprats grow to full size slowly. It is not known what triggers their reproduction, or how long it takes. Although, from the number of adult specimens we see with missing limbs, but without nearby sprats, it seems many of the sprats fail to thrive.
While Homo Patternenvelopus tends to congregate in twos and threes, they are not especially social animals, and often seem to treat each other with disdain, as you see here.
Remember that these creatures can be quite dangerous. Keep your hands inside the vehicle at all times. If provoked, their lightning reflexes and razor-sharp teeth can cause serious damage, or even death.
