Rhinopristiformes is an order of rays, cartilaginous fishes related to sharks, containing shovelnose rays and allied groups.[1][2][3][4]

Families[edit]

Additional families

Two additional families are associated with the order but their phylogenetic relationships have not been fully resolved:

Characteristics[5][edit]

Rhinopristiformes are are generally

  • Slow Growth
  • Late Maturity
  • Low Fecundity

Thus causing them to be susceptible to extinction.

Extinction[5][edit]

Rhinopristiformes are more prone to being caught in many different types of fishing equipment. Those include the following

  • Trawl
  • Gillnet
  • Seine Nets
  • Hook and Lines

They are caught for their meat but most importantly their fins. While the meat is mostly consumed locally the white fins are a delicacy and highly sought after. They are the most valuable part of Rhinopristiformes therefore their fins are in high demand. Both the combination of overfishing and the high desire for their fins the Rhinopristiformes population is depleting rapidly
