Kashyapa’s wife Arishta gave birth to 13 apsaras – Alambusha, Mishrakesi, Vidyulparna, Tilottama, Aruna, Rakshita, Rambha, Manorama, Keshini, Subahu, Suraja, Surata and Supriya. She also gave birth to four gandharvas – Haaha, Huhu, Atibahu and Thumburu.

But as per Ramayana Balakanda Chapter 65 verse 32, Vishnupurana Ansh 1 Chapter 9 and Agnipurana Chapter 3, apsaras were born during the Samudra Manthan and numbered in thousands.
