Sperm whale has the largest brain on Earth, more than five times heavier than a human's. Sperm whales can live for more than 60 years. Spermaceti (sperm oil), from which the whale derives its name, was a prime target of the whaling industry, and was sought after for use in oil lamps, lubricants, and candles. Ambergris, a solid waxy waste product sometimes present in its digestive system, is still highly valued as a fixative in perfumes, among other uses. Beachcombers look out for ambergris as flotsam. Sperm whaling was a major industry in the nineteenth century, immortalised in the novel "Moby Dick".
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.
