It’s the most common shark in the Puerto Vallarta area, they are what you would call a vacuum shark which is how they normally feed. They tend to stay most of the time invisible and completely still in the sands of shallow waters.
Recognizable for the white tip on the tip of their dorsal, tail and pectoral fins. You need to go searching for them to see them as they rarely wander within the bay because they live in deeper and colder waters.
One shark species that is a not so rare visitor in the bay is the Whale Shark (Rhincodon typus), a harmless plankton-feeding shark, the largest fish in the ocean.
