Eversible proboscis of an acanthocephalan parasite from the gut of a bluefish, differential interference contrast illumination
The Acanthocephala is a phylum of parasitic worms distantly related to nematodes or roundworms. They have a characteristic spiny proboscis that can be withdrawn within the body or everted into the gut lining to anchor the woirm and prevent its being dislodged by peristalsis. here, the muscles that retract the proboscis are revealed as blue because of interference illumination called DIC or Nomarski
