Made these guys. They are quadrupedal piscivores, ambush hunters. They stand in water, waiting to grab anything that comes by with their dextrous forward appendages, then consuming it whole as their main food source, similar to wading birds. They have four eyes: two for frontal binocular vision for hunting and a second pair positioned more on the side of their head for 360-degree vision for spotting predators. Their hair grows from their back as protection and camouflage, and they have short tails. They have 2 sexes with minimal sexual dimorphism; they reproduce sexually and via egg laying and often build small artificial islands out of plant materials as nest structures. They would usually stick together in groups for protection and help each other out.

They evolved from pseudo-monkeys that faced their climbing habitat being receded by rising water, leading to their change in behavior to hunting aquatic life by standing in shallow water swamps via grabbing 'fish'. Over time, this would lead to longer legs and loss of hair on the lower body and shortening of their tail.

Then they figured out they could use their nest construction skills to build damns and fences to control water flow and 'fish' populations. Leading to the start of their technological development.
