ONE of two oarfish found in California waters earlier this month had a host of parasites living in its giant, serpent-like body.

Scientists from the University of California, Santa Barbara last week dissected the 18-foot (5.5-metre) oarfish found off Catalina Island and found large, larval tapeworms in its intestine. An adult spiny-headed worm also was found embedded in the intestine.

Scientists say the discovery of the parasites is important because it tells them what the natural enemies of the oarfish are and could indicate where the elusive fish lives or hunts for food.

A snorkeler found the carcass of the oarfish Oct. 13. Several days later, another oarfish washed ashore in Oceanside.
It's not known how either died.

The rarely seen deep sea-dwelling creatures can grow to more than 50 feet (15 metres).
