Answer:
"Cobra-de-água-de-colar" (Natrix natrix) is a Portuguese equivalent of "ringed snake" (Natrix natrix).
The feminine noun "cobra" takes "a" ("the") as its singular definite article and "uma" as its singular indefinite article. The preposition "de" means "of, from." The feminine noun "água" means "water." The masculine noun "colar" means "necklace." Its singular definite article is "o," and its singular indefinite article "um."
All together, the pronunciation is "KOH-bruh DJAH-gwuh djee KOH-luhr."
