Area restrictions
Leave shark egg cases where they are in shark refuge areas.
Habitat
Female sharks lay these commonly observed purse-like egg cases in shallow coastal areas around seagrasses, seaweeds and kelp beds. The long tendrils, which are very supple when first laid, wrap and tangle around these structures. The tendrils then become very wiry and strong on contact with the sea water and difficult to break off. Empty cases are often found washed up on beaches.
