The fish, sharks, tortoises and snakes were most agitated and perturbed. The entire ocean became turbulent, and even the large aquatic animals like whales, water elephants, crocodiles and timiṅgila fish [large whales that can swallow small whales] came to the surface. While the ocean was being churned in this way, it first produced a fiercely dangerous poison called hālahala.
