- n. a very large shark (Cetorhinus maximus), inhabiting the northern coasts both of Europe and North America. It sometimes becomes forty feet in length, being one of the largest sharks known; but it has small simple teeth, and is not dangerous. It is captured for the sake of its liver, which often yields several barrels of oil. It has gill rakers, resembling whalebone, by means of which it separates small animals from the sea water. Called also basking shark, bone shark, hoemother, homer, and sailfish; it is sometimes referred to as whale shark, but that name is more commonly used for the Rhincodon typus, which grows even larger.
