A shocking video shows a 50-foot-long beached whale washed up on the shore in Delaware, USA.<br /><br />The videos, filmed on Sunday, near the Indian River Inlet Bridge in Sussex County, show the huge mammal lying motionless as spectators gather to take a look.<br /><br />A representative from the Marine Education, Research, and Rehabilitation Institute (MERR) confirmed that the whale was a sub-adult fin whale.<br /><br />According to MERR, fin whales are an off-shore, deep-sea species that would not usually be near the shore unless they are very weak.<br /><br />MERR officials did attempt to sedate the animal, but couldn't get close enough due to high water levels and strong waves.<br /><br />The whale sadly didn't survive.
