Ukjaw

The ukjaw split from it's ancestor the ukback. Due to competition with the needlewing, the ukjaw became a higher predator then it's ancestor. It now feeds on the needlewing and the common fraboo, another large species of the Ichthy Temperate Riparian to pray upon. Since needlewing was able to sprint away from danger, the ukjaw need to be able catch its pray and keep it down. This is how it developed its "jaw", which is made of its two arms and its proboscis. The proboscis at the moment immobile, but its arms work fine as mandibles. They also have light blue spots to blend in with the pioneer groovestalk.

When hunting needlewings, the ukjaw will squat down to the ground and wait for one to pass by. The ukjaw will once and a while use its grasping tail claws to make clicking sound to alert any other ukjaws in the area. If there are more then one ukjaw in the area, one will walk away before chasing after the pray or they'll see who can get the pray first and the loser will leave immediately. Then the ukjaw would sprint torwads the needlewing before it can run away and "bite" the needlewing and keep it down on the ground as it injects digestive juices into the needlewing. The ukjaw is also able to crack the shell of the common fraboo, "with effort". They'll often spit digestive juices onto the shell to make the job easier.

They are solitary and will only meet to mate in the spring. Since their pray lead to drier areas, they lay soft shelled eggs in the sand. Instead of having a larva stage, they know give birth to immature offspring, which look like a cross between uksip terricola and the stumpworm sucker. They do not take care of their offspring. The offspring will scavenge for food until they become adults.
