Shark Family Tree

Oxynotidae: Roughsharks

The Family Oxynotidae (or Roughsharks) includes five unmistakable species of small sharks with rough skin; flat, blunt snouts; small, thick lips; and close-set large nostrils. They’re easily spotted by their paired extreme, high-spiked dorsal fins and stout, triangular cross-sectioned bodies and lack of anal fins. And don’t they look a bit look footballs with fins? They have been spotted in waters across the globe.
