Arm Sturge
Size: body size is 6 centimeters, arm length is 20 centimeters
Captopiscus salsamembri, the ‘Arm sturge’, is a saltwater descendant of the Hugger Sturge (C. amplexus). Due to the extinction of most larger musculates the Hugger Sturge had to adapt so it entered the realm of the substrate using its arms to search out dead polyphs and carrion from the bottom of zone 10. Though preferring to stay on the bottom Arm Sturges can and will swim when needed by folding their arms behind them so they do not get in the way. The Arm sturge did not develop with any predators and primarily feeds on dead polyphs and occasionally carcasses. The other change besides longer arms is that C. salsamembri is able to tolerate salt water, as it lived in brackish water this was an easy transition to make. To survive the barrage of salt the Arm Sturge’s kidneys pump out extraneous salt to maintain the osmolarity of it's ancestor. The Arm Sturge retains it’s ancestors coloration as there was no reason to lose it and this is still used to impress mates. Batches consist of 20-25 eggs, which are still relatively large and held in for the same amount of time as their ancestor did to give them a developmental head start. When they deposit their eggs they simply attach them to rocks, the eggs hatch within 2 weeks and grow to maturity in 3 months.
The Arm Sturge avoids feeding on Sectionalfolia podius to avoid getting poisoned by salt, which could be fatal.
