HONOLULU, Hawaii - Whale experts believe a sick whale spotted off Kauai this week may be suffering from scoliosis or curvature of the spine.

It's a rare disorder but scientists say they have seen it in other marine mammals like dolphins.

The National Oceanic and Atmospheric Administration's marine mammal response co-ordinator, David Schofield, says officials are confident the whale was either born with the condition or acquired it over the course of its life.

The Honolulu Star-Advertiser newspaper reported Friday that Schofield ruled out a boat collision, saying it's not plausible an animal hit by a boat would have retained the shape of such an injury.

A flight instructor on Kauai spotted the white, emaciated whale with a severely deformed spine on Monday. He said the 50 foot whale "appeared to be bent in half."
