Spinomandrus lutumandrus
(Mud Spinomandrus/ 'Mud Mandrus')
Evolved from S. rostrodontus that eventually breached to shallow waters of zone H muddy swamp. This species became smaller due to the smaller canals and developed a mud like pigment to camouflage itself.
Found in water canals, ponds and rivers of zone H they get only 1.8 feet long. They have shorted sails so they can camouflage better in the mud. They are usually covered in mud and are seen staying stationary to ambush their prey. To avoid larger species such as T. gigagammas stomping on it they are able to use their head to burrow(still not a good skill) to the ground to avoid getting squashed by any large heavy species. They are also able to drag themselves out of water to crawl/slither to a new source if food is running low or the water is drying out. They feed on V. colonisuchus, V. coxaeiuncturam, fallen plant matter, baby D. acrotyrannus and baby A. oculus. They are ambush predators usually staying still until prey disturbs the surface which it then jumps and grabs the prey. It would then drag it into the water and trashed its prey. The prey would then suffer from bleeding and drowning. It would then feast on its prey.
When breeding they would lay eggs under mud( up to 60-100 eggs but only 2-6 survive). When eggs hatch the larvae contain gills but are able to breathe in the low oxygenated environment. Young will hatch at 5cm feeding on dead matter, plant matter, biofilm, baby V. colonisuchus and baby V. coxaeiuncturam. Once they reach subadult they will start to consume prey and start acting like adults. Cannibalism is frequent which they would usually eat the runts so they can develop faster and become bigger in a few days. Juveniles will feed during day and night while rest in dusk and dawn.
