What is the main difference in pronunciation between the English "t" and the Spanish "t"?

"The English and Spanish "t" are pronounced similarly, although the sound in Spanish is softer and with the tongue placed lower. "T" in both alphabets comes via Latin from the Semitic family of languages. In words shared by the two languages, the Spanish t is usually "t," "th," or "c" in English."
