Abstract: The species scale provides an upper bound on the ultraviolet cutoff of gravitational effective theories coupled to a number of light particle species. We derive a moduli-dependent expression of the species scale from the entropy of the smallest possible black hole in type II Calabi-Yau compactifications, matching with a recent proposal from the topological string. Then, we argue that the number of species has to be understood as an entropy, we propose a notion of energy and temperature of species and we discuss the laws of species thermodynamics. They have direct connection to established swampland conjectures and lead to a thermodynamic interpretation of them.
