Bordallo Pinheiro's sardine.


A sardine (sardina pilchardus, "sardinha" in Portuguese) is a fish commonly found in the Northeast Atlantic and Mediterranean, where it inhabits the water column in coastal zones between 25-100 m of depth. It has an elongated body covered with scales, with a darker blue-silvery coloured back and lighter silvery coloured sides and belly. It spawns from October to April when it is leaner, and females can release 50,000 to 60,000 eggs. Sardines are a much appreciated delicacy in Portugal, most prominently at city summer festivals such as Santo António festival in Lisbon.
