Here lately, the Bullock Texas State History Museum is celebrating all things fast and bitey with a “Sharks” exhibit, film screenings like short documentary “Great White Shark,” and now this free noontime lecture from Matt “The Shark Guy” Marchant. Take an immersive journey with Marchant, who’ll dive deep into shark anatomy, physiology, behavior, and more using stunning visuals and a gripping narrative taken from his years of experience as a shark photographer, author, and conservationist. – Kat McNevins
