Etymology The name comes from latin fonte = fountain, and frida as an abbreviation of frigida = cold. ‘Fontefrida’ is the title of an anonymous Spanish romance from the Middle Ages. In this romance, ‘fontefrida’ is a place where consolation can be found. The word ‘shinkai’ in Japanese means ‘deep sea’; hence, Shikai fontefridae means ‘the deep sea cold fountain’. [details]
Habitat Usually one male and one female within each Calyptogena kilmeri clam, found between gill lamellae and the foot, except for some specimens (SIO-BIC A1375, A1384) found in another host, Vesicomya gigas. The specimens living within V. gigas are morphologically very similar to those living within Calyptogena kilmeri. [details]
Morphology Sexually dimorphic, with males uniformly pigmented pink, females longer and wider, with larger midbody notopodia full of yellow oocytes. Females’ body usually longer than males . First segments with one groove ventrally located on the base of each parapodia that are more conspicuous in females. [details]
