The first use of buttons is attributed to the Indus Valley. Buttons were carved from seashells and used primarily as an ornament rather than a fastener. An individual’s social or political status could be determined by the buttons attached to their clothing. Gold buttons obviously ranked higher than those made from seashells.

Sphyrna lewini - The Sphyrnidae family consists of 11 known hammerhead shark species; “sphyrna” is the Greek word for hammer. The scalloped hammerhead is the most common shark in this family and can be found throughout the world’s tropical and temperate coastal waters. The eyes and the nostrils are set on opposite ends of its elongated head. The unusual design of having the eyes set on the side of the head provides the hammerhead shark the advantage of being able to search for prey with a wider field of vision.
