Streblospio benedicti
WEBAug 17, 2023 · Description: Streblospio benedicti (also called the Ram's horn worm) is a small polychaete native to the Western Atlantic, where its distribution ranges from the Gulf of Saint Lawrence to Venezuela.Sexual maturity is reached at around 9 to 14 weeks and populations and individuals may vary during development.
Comparative Hox genes expression within the dimorphic annelid
WEBDec 21, 2023 · We compare the expression of eleven Hox genes found within Streblospio benedicti, a marine annelid that produces two types of offspring with distinct developmental and morphological features. For these two distinct larval types, we compare Hox gene expression through ontogeny using HCR (hybridization chain reaction) probes for in-situ
