Oliva porphyria - The tent olive is one of about 10 mollusk species within the Olividae family. The tent olive remains buried beneath a shallow layer of sand or mud during the day and emerges at night to begin the search for food. They use their powerful foot, an appendage large and strong enough to seize and drag their food source underneath the sand where it is then consumed. The tent olive ranges from 30 to 135 millimeters in length and is found from the Gulf of California to Peru.

El Salvador is the smallest and most densely populated country in Central America. The first people to settle the region were the Pipils, also known as Cuzcatlecs. They established a loosely defined state known as Cuzcatlán, a confederation subdivided into city states and small chiefdoms. The Pipils were skilled in weaving cotton textiles and cultivated cacao, a commodity traded as far north as Teotihuacan. The Cuzcatlán state fell with the arrival of the Spanish conquistadores in the early 16th century.
