Abstract: The excellent particle identification and momentum measurement capabilities of the \mbox{ALICE} detector allows for the identification of dueterons and \he\ and and their corresponding anti-nuclei. This is achieved via the measurement of their specific energy loss in the Time Projection Chamber and the velocity measurement by the Time Of Flight detector. Moreover, thanks to the Inner Tracking System capability to separate primary from secondary vertices, it is possible to identify (anti-)hypertritons exploiting their mesonic weak decay ($\rm ^{3}_{\Lambda}{H}$ $\rightarrow$ $^{3}\rm{He}$ + $\pi^-$).Results on the production yields of light nuclei and anti-nuclei in Pb--Pb and p--Pb are presented, together with the measurement of hypertriton production rates in Pb--Pb and upper limits for the production of lighter exotica candidates.The experimental results are compared with the predictions of both thermal (statistical) and coalescence models.
