Asterophila distribution in Antarctica. a Host specimens infected by Asterophila (left: P00407, right: P00340)- white circles indicate cysts on the asteroid arm. b Asterophila specimens retrieved from hosts (left: M13618, right: M12882). c Localities marked with a square denote locations where Asterophila was present, and localities marked with a circle represent locations where hosts were sampled but Asterophila was absent (Wikimedia Commons contributors). d Detailed sampling map showing co-distribution of Asterophila species at South Shetland Islands created with the R package ggplot2 [27] and with bathymetry data from the National Oceanic and Atmospheric Administration (NOAA) in the R package marmap [28]
