How do amphipods reproduce?
Copulation in most gammaridean amphipods occurs a few minutes after the female molts (Hynes, 1955), which is preceded by the female’s release of eggs into the egg pouch (marsupium), where fertilization occurs.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
