  We investigate black brane solutions in asymptotically Lifshitz spacetime in
3+1-dimensional Horndeski gravity, which admit a critical exponent fixed at
$z=1/2$. The cosmological constant depends on $z$ as $\Lambda=-(1+2z)/L^{2}$.
We compute the shear viscosity in the 2+1-dimensional dual boundary field
theory via holographic correspondence. We investigate the violation of the
bound for viscosity to entropy density ratio of $\eta/s\geq1/(4\pi)$ at
$z=1/2$.
