About the star :

Deneb Kaitos (also Dhanab Qaytus) is from the Arabian Al Dhanab al Kaitos al Janubiyy, the "Tail of the Whale towards the South" -- the "Southern Branch of the Tail" in Cetus.

Very differently it was the Arabs' Al Difdi¹ al Thani, the "Second Frog", that we see in the present Difda, or Ad-Difdi', "The frog". Latinized as Rana Secunda [the star Fomalhaut being Al Difdi' al Awwal, the First Frog].
