Looks like a tea-straining spoon (has natural fenestrations) or a leaf.
The stalk of this leaf shaped structure, the petiole, attaches to the superior internal aspect of the thyroid cartilage midline via the thyro-epiglottic ligament. The hyo-epiglottic ligament attaches the anterior epiglottis to the hyoid.
In response to food/liquid boluses, there is contraction of the lateral crico-arytenoids, transverse and oblique arytenoids, and ary-epiglottic muscles brings the ary-epiglottic folds together and pulls the arytenoid cartilages toward the epiglottis.
Vagus nerve innervates some taste buds on the epiglottis.
The superior border of the epiglottis forms the inferior border of the oropharynx.
