Whale be used as another indication of animal intelligence. Sperm whales have the largest brain mass of any animal on earth, averaging and in mature males, in comparison to the average human brain which averages in mature males. The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. Small whales are known to engage in complex play behaviour, which includes such things as producing stable underwater toroidal air-core vortex rings or "bubble rings". There are two main methods of bubble ring production: rapid puffing of a burst of air into the water
Bahamut This account is also found in al-Tha'labi's "Qiṣaṣ al-anbīyāʾ", but in that version God forces the whale (Lutīyā) into submission by sending a creature that invaded through its nose and reached its brain; it also claims to be an anecdote on authority of Kaʿb al-Aḥbār (d. 650s A.D.), a convert considered the earliest informant of Jewish-Muslim tradition to Arab writers. Although this is an instances of an Islamic tale that ascribes the origins of earthquakes to the cosmic whale/fish supporting the earth, more familiar beliefs in medieval Islam associate the earthquake with the bull, or with Mount Qaf.
