Mermaids Purse Photo by @daviddoubilet A baby swell shark 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 9-12 months depending on water temperatures. The empty cases sometimes wash ashore and are called a #MermaidPurse. Swell sharks got their name from their ability to ingest seawater to double their size to discourage predators.
