The largest eggs in the world are laid by a shark?
Most sharks do not lay eggs, but instead bear live young, with
the shark fetuses supported by the mother in a manner similar to
mammals. Some others have eggs, but the eggs remain inside the
mother, with the young living off each other. Of the remainder,
some simply lay them on the bottom of the ocean, while others place
them in crevices. Some of the bottom-laid eggs have long streamers
that grab onto nearby objects and hang on until the young are
born.
