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

Families

Rhinopristiformes contains the following families:[5]

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

The following fossil genera are also possibly rhinopristiforms, but phylogenetic relationships are uncertain:[7]

The spathobatids, an extinct group of rays from the Late Jurassic of Germany, convergently evolved to closely resemble guitarfishes, but are not thought to be related to rhinopristiforms.[9]

Characteristics

Species in the order Rhinopristiformes generally exhibit slow growth, late maturity, and low fecundity. Alone or in combination, such features cause fishes in this group to be susceptible to extinction.[10]

Threats

Rhinopristiformes are more prone to being caught in many different types of fishing equipment, including trawl, gillnet, seine net, and hook-and-line.

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 has caused the Rhinopristiformes population to rapidly decline.[10]
