A lone remora, photographed during a scuba dive at Octopus Wall in Dar es Salaam. Remoras, sometimes called suckerfish, grow 30-90 cm long and attach to sharks, manta rays, whales, turtles, dugongs and other large fish. Some small remoras travel in the mouths or gills of large manta rays, ocean sunfish, swordfish, and sailfish. This remora is in desperate search of a host, it even tried attaching to a diver’s tank!
