Algerian prawns, especially those of Bona, are large and of a delicate flavour.
This estuary they called the Rio dos Camaroes (the river of Prawns), from the 2 abundance of the crustacea found therein.
The name of "pink shrimp" is given to Pandalus montagui or annulicornis, which turns red on boiling and which resembles in form the larger "prawns," having a long rostrum or beak, saw-edged above and below.
The larger shrimp-like crustacea are generally known as "prawns," the name being especially applied in Britain to the species Leander serratus, formerly called Palaemon serratus, which is highly esteemed for the table.
The large river-prawns of the genus Palaemon (closely allied to Leander) found in most tropical countries are also often used as food.
