We all know of the relationship between anemone species and fish of the Amphiprion genus, but there are other species that associate with anemones as well, some for just part of their lives. It’s widely believed that these mutualistic relationships are only found in tropical waters, but [...]

The genus Hoplophrys is monotypic, containing the single species H. oatesi. These minute, true crabs [...]

The pairing of pistol shrimps with watchman gobies is a common sight on Indo-Pacific coral reefs, as well as in the home aquarium, but few aquarists are aware of the strange relationship that exists along the Western African coastline between an altogether different goby and [...]
