what is this alligator ?

not everything has to have a reason. i just thought it looked cool, so i used it.

i found it on this page regarding lattice qcd (quantum chromodynamics), whatever that means

turns out this image was the 1990 - 1999 logo for the international symposium on lattice field theory

pretty cool logo, i dont know why they changed it. i hope they are okay with me using it :~]
