Spectmeber 2024 Day 26: Northern Shark-Sturgeon
The Shark-Sturgeons are a Potworian family of oceanic, sharp-toothed sturgeons that have evolved from bottom-feeding ancestors to occupy a predatory niche similar to those of Earth’s lamniform sharks, use their sensory pits and barbels to detect the electric signals produced by their prey, and are mainly found across the temperate to subtropical waters of the planet’s northern hemisphere. While many shark-sturgeon species reach average sizes of 2.5 to 4 meters long and weigh about 140-185 kg, The Northern Shark-Sturgeon, which inhabits the cold, icy waters surrounding Potworia’s northernmost continent of Gniazdoia, is the largest of them all and can reach adult sizes of around 5.5 to 7.3 meters long and weigh over 1,223 kg. The voracious fish can move at shorts bursts of speed of up to 73 km/h and preys upon smaller, fast-moving fish such as the Angel-Gar, oceanic birds such as shearwater-like passerines and large, flightless puffins, and mammals such as the seal-otters and certain species of small whale-moles. The females migrate upstream into Gniazdoia’s rivers to lay their eggs, and the juveniles will soon move into larger bodies of water such as lakes and estuaries as they grow larger and are eventually old enough to swim into the open ocean.
