rhinoceros
犀 centers on the rhinoceros, a large thick-skinned animal with one or two horns.
犀 is thought to combine 尸 (here representing a body or hide) with a phonetic element that also suggests the animal's tough skin. The exact historical development is uncertain.
The top 尸 looks like a thick hide or body, and the lower part suggests the heavy legs and horn of a rhinoceros. Picture a rhino's tough shape under that outer covering.
For サイ, imagine a rhinoceros sighing loudly: sigh -> サイ, as the rhino lets out a deep breath.
