Ryan Photographic - Thoridae - Broken-back or anemone shrimps
There are currently 207 species of thorid shrimps classified into nine genera. The family was originally included in the Hipploytidae but molecular evidence suggests that they should be a family in their own right.
Several species appear to be restricted in their distribution while others, such as Thor amboinensis is found in both the Atlantic and Pacific oceans (although I suspect that further genetic analysis will show these to be distinct species.)
