Totoaba - Totoaba macdonaldi

From WikiAnimal

The Totoaba or Totuava (Totoaba macdonaldi) is a species of marine fish, a very large member of the drum family Sciaenidae that is endemic to the Gulf of California in Mexico. It is the only species in the genus Totoaba. The totoaba is caught for its swim bladder, which is smuggled to China for sale on the black market. The illegal fishing methods used to catch totoaba, particularly gillnets, have proven disastrous for the vaquita population.
