### Description

At BESIII, the electromagnetic form factors (EMFFs) and the pair production cross
sections of various baryons have been studied. The proton EMFF ratio |GE/GM| is
determined precisely and line-shape of |GE| is obtained for the first time. The recent results of neutron EMFFs at BESIII show great improvement in comparison with previous experiments. Cross sections of various baryon pairs ($\Lambda, \Sigma, \Xi, \Lambda_c$) are studied from their thresholds. An anomalous enhancement behavior in the $\Lambda$ and $\Lambda_c$ pair cross sections is observed.
