does every particle have an antiparticle?



does every particle have an antiparticle?
all particles have their respective antiparticles ,
 if we have matter, then there  is antimatter, from antimatter we get antiatoms to antibaryons to antiprotons and antineutrons which are all composed of anti-quarks.
the fundamental antiparticle is the anti-quarks, when particles collide with their corresponding antiparticles they annihilate, annihilation is a process that occur when particle and antiparticles completely decay into photon when they meet,
