These organisms play an integral role in the ecosystems of the Gulf of Mexico (GOM), where not only are they a keystone species, but are also socioeconomically important. The survival of embryonated eggs is necessary to ensure adequate recruitment into the next generation. Because the 2010 Deepwater Horizon oil spill (DWH) occurred during the peak of the blue crab spawning season, the incident likely impacted blue crab embryos. In order to assess the effect of oil on embryonic growth and development, we collected embryonated eggs from seven different female blue crabs from the GOM throughout the spawning season and exposed them to an oil concentration of 500 ppb (the approximPeerJe5985https://www.ebi.ac.uk/biostudies/studies/S-EPMC6294050biostudies-literatureEffects of crude oil on survival and development in embryonated eggs in <i>Callinectes sapidus</i> Rathbun, 1896 (Decapoda, Portunidae).PMC6294050Kelly KLTaylor CMfalseEffects of crude oil on survival and development in embryonated eggs in <i>Callinectes sapidus</i> Rathbun, 1896 (Decapoda, Portunidae).Blue crabs, <i>Callinectes sapidus</i> Rathbun, 1896, are ubiquitous along the Atlantic and Gulf coasts of the USA.
