Regardless of the research currently being summarized by BOEM as determining the “electric powered area created” at the positioning wouldn't have an impact on horseshoe crabs, that wasn’t what it discovered.
No experiments happen to be finished, all this is concealed in the shroud of secrecy. We will’t even find out how Most are supposedly returned to the h2o,” Harlan extra.
And they're about to save even more life, mainly because they're playing their part while in the generation of a Covid-19 injection.

Whilst quite a few endure the ordeal, study suggests that the extraction can have an impact on their actions and survival. For that reason, You will find there's growing push within the scientific community to create synthetic alternatives that could satisfy exactly the same function in endotoxin detection without having impacting horseshoe crab populations.
