Recent progress on the dectection of antimatter particles at RHIC is briefly reviewed. The observations of the anti-hypertriton ()and anti-helium-4 nuclei ( , or ᾱ) from the RHIC-STAR Collaboration are highlighted. In addition, preliminary lifetime measurement of and energy dependence of strangeness population factor are presented. The mechanism of light antinuclei production is also discussed.
