根据对687个标本的详细检查和2000年的甲壳长度数据，对东北大西洋豪猪湾的三刺Geryon（Herbst）进行了研究。 有证据表明，男性成为性成熟的甲壳长度为30-35毫米，和女性之间的12和15毫米。可能有一个终端anecdysis，在男性在55-65毫米和女性在45-50毫米。 在螯和腹部的相对增长遵循预期的模式，除了右螯的男性在青春期换羽的相对大小下降。 季节性繁殖：9月/10月产卵，次年5月孵化，8月/9月从浮游生物定居。
A study was made of Geryon trispinosus (Herbst) from the Porcupine Seabight in the north-east Atlantic, based on detailed examination of 687 specimens, and carapace length data for a further 2000. Evidence indicates that males become sexually mature at 30-35 mm carapace length, and females between 12 and 15 mm. There is probably a terminal anecdysis, in males at 55-65 mm and in females at 45-50 mm. The chelae show limited heterochely and marked right-handedness in both sexes. Relative growth in chelae and abdomen followed expected patterns, except that the right chelae of males decreased in relative size at the puberty moult. Seasonal reproduction is indicated: laying in September/October, hatching the following May, and settlement from the plankton in August/September.
