What anatomical feature related to feeding position distinguishes the whale shark's mouth compared to many other sharks?
Answer
It is located terminally at the front of its flattened head
A key morphological detail used in the taxonomy of *Rhincodon typus* concerns the placement of its mouth. Many shark species possess an underslung mouth, meaning the opening is situated on the underside of the head. In contrast, the whale shark features a massive mouth positioned terminally, meaning it is located directly at the very front end of its head. Furthermore, this terminal opening is situated on a head that is characteristically flattened. This physical arrangement is intrinsically linked to its feeding strategy, facilitating the massive intake of water necessary for its filter-feeding existence.
