This is a print on demand publication. Associations of copepods with marine invertebrates are common, especially in tropical waters. In the 25 years before this review was written in 1982, a large number of new copepod associates were discovered. In 1982 the number of species of copepods known to be associated with marine invertebrates was estimated to be about 1,300. This review encompasses all copepods, ranging from loosely associated to endoparasitic forms, which are associated with Actiniaria (sea anemones) & Corallimorpharia (anemone-like forms). For each of the 42 species of copepods information is given on the host, the site on the host when known, & the locality. New species are fully described. For known species brief notes are provided.
