Humans’ fascination with sharks seems insatiable. Consider the popularity of Discovery Channel’s Shark Week, the resonating legacy of Jaws, and even the cult hit Sharknado. For Santa Barbarans, shark sightings aren’t just via television, however; the toothy critters have been spotted up and down our coastline. To educate folks about the giant finned fish, the S.B. Maritime Museum (SBMM) has invited Ralph Collier, a leading expert on Pacific Coast white shark behavior and ecology, to give a talk titled Should I Get a Bigger Boat? Shark Attacks on Boats, People, Dogs, and Seals. Collier will share current theories as to why sharks go after surfboards, boats, crab traps, and people. Peter Howorth, the director of the S.B. Marine Mammal Center, will join Collier, giving insight into how studying shark attacks on marine mammals can serve as warnings of potential strikes to the human population. The lecture takes place Friday, August 8, 7 p.m., at SBMM, 113 Harbor Way. For reservations and information, call 962-8404 x115 or visit sbmm.org.
