Electromagnetic baryon form factors are excellent tools to investigate the hadronic structure. Many unexpected features have recently been found by BESIII and other experiments concerning e+eNN¯ as well as e+eBB¯ close to their thresholds, such as oscillations in the proton time-like effective form factor as a function of the energy and steep steps in the cross section at threshold followed by a plateau in e+epp¯, and similar behaviour in e+eΛcΛ¯c or in other e+eBB¯ cross sections. Recent unxpected results for e+eΛΛ¯ are reported as well.
