rocks, molluscan shells, and vestimentiferan tubes), on two occasions we found them attached in great numbers to the telsons
of common bythograeid crabs.
entomon started to burrow back into the sediment, leaving just their telsons
To identify each female within the same group, part of the telson
was cut with the exception of five females and latter sampled to test gonadosomatic index (GSI) and hepatosomatic index (HSI).
For the females with intact telsons
, when the ovary of the first female developed to stage VI, they were weighed and dissected, while keeping them on ice, to determine the gonadosomatic index (GSI = 100 x gonad weight/total body weight) and hepatosomatic index (HSI = 100 x hepatopancreas weight/total body weight).
