This weeks Creature..."Glacier Terror"...

This member of the shark family lives in the arctic regions of the planet. It uses a large, air filled, snow white, cartilage crest attached to her skull that floats at the waters surface. It lies motionless near the edge of glaciers where it can use it's camoflage to blend in with the icebergs. The shark can slow its metabolism for extended periods allowing large pods of seals to gather on top of her crest...when enough prey is present the shark slowly raises it's pectoral fins, with a violent thrust she pushes her mass out of the water tilting her crest so prey falls towards the mouth. The percussive impact is enough to stun and disable most prey. This terror of the glaciers can decimate seal pods by 75% and has even been seen preying on Polar Bears and the occasional eskimo.
