Subject: Anker’s Whip Coral Shrimp (Pontonides ankeri) is a small shrimp that lives solely on whip coral species. Females are usual twice to three times the size of the males. One whip coral will only host a single pair of these commensal shrimps. The swollen lump is a parasitic Bopyrid isopod (Bopyridae) which have infected its gills.
Technique: Movement is important in video, without movement an image will be boring after less than 5 seconds. This little shrimp was moving around the coral so unhurriedly that it took him more than 30 seconds to crawl not even halfway around the tiny coral twig. So besides a little boost in saturation and contrast, the footage was sped up two-fold.
