OSAKA, JAPAN:  Offspring of a "draughtsboard" shark moving inside translucent egg shells are seen at a water tank in the Kaiyu-kan aquarium in Osaka 07 May 1999.  The shark eggs have become very popular since they were first exhibited in March at the aquarium.  When the embryos reach 15 cms in length in about one year, they will be born from their 12cm-long and 5.5cm-wide shells.

Episode show notes:

Welcome to Shark Week: The Podcast! Dive in with marine biologist and shark expert Luke Tipple as he illuminates little-known shark facts through the stories of his deep-sea ocean adventures. During this episode, Luke discusses the biology of sharks and the life cycle from mating to birthing – and speculates what a spectacle two hammerheads mating in the wild would be like. As he continues, he examines the details about shark species that can live up to 100 years or longer and how sharks likely evolved into the majestic apex predators they are today.

Please note that there is a cheeky mention of sharks mating from 4:41 to 5:15 Listener discretion is advised.
