Abstract
The sea anemone Calliactis tricolor (Le Sueur, 1817) is an ecologically important member of the benthic community in coastal and coral reefs of the tropical Atlantic, particularly for their propensity to establish mutualistic symbiotic relationships with hermit crabs. This species is presumably distributed throughout the Gulf of Mexico; however, it had never been recorded in the southwestern part of the Gulf. Here we document the first record of C. tricolor in 2 coral reef localities of the Veracruz reef system, Mexico, and update the number of species of sea anemones known for the region.

Summary
Calliactis tricolor (Le Sueur, 1817) is one of the most well-known sea anemone species inhabiting coral reefs and shallow coastal waters of the western Atlantic. Particular attention has been paid to this species due to its propensity to establish close mutualistic symbiotic relationships with hermit crabs, such as Pagurus pollicaris Say, 1817, Dardanus venosus (Milne-Edwards, 1848), Dardanus fucosus Biffar and Provenzano, 1972, and Petrochirus diogenes (Linnaeus, 1758), among other crustaceans (Cutress and Ross 1969, Cutress et al 1970, Mariscal 1972, López-Victoria et al 2004). In this symbiotic relation, 1 to several individuals of.
