(Somewhere in the Tetra Galaxy)
Lesser Ithraks are a species of nocturnal predators which evolved somewhere within the Tetra Galaxy, although the exact location is unknown. While considered tough predators to contend with, they are dwarfed in comparison to the Greater Ithraks, which they are obviously related and are considered a cousin species to. As with their larger cousins, they are noticeably weaker when clinging to the ceiling.
If approached by a potential threat, they will swing from their ceiling positions and vocalize a warning in an attempt to scare away the intruder. If this does not work and the threat draws nearer, they will hop down to the ground and proceed to attack it by lunging at it.
