A swell shark embryo called a pup grows inside a rubbery sac attached to a piece of seaweed. The pup will feed on the round yolk until it emerges in 9+ months depending on water temperatures. The empty cases sometimes wash ashore and are called a “mermaids purse”
Swell sharks get their name from their ability to ingest water to double their size to discourage predators. //
