Question: List of territorial entities where Portuguese is an official language -- Although Brazil is the only Portuguese-speaking nation in South America, it has the largest population, area and economy on the continent. Thus, the South American trade bloc Mercosul uses Portuguese alongside Spanish as its working languages. A Spanish influenced Portuguese dialect is spoken in the northern Uruguayan border area with Brazil.

Question: Spiny dogfish -- The spiny dogfish, spurdog, mud shark, or piked dogfish (Squalus acanthias) is one of the best known species of the Squalidae (dogfish) family of sharks, which is part of the Squaliformes order.
