The Dorsal Fin

Underwater filmmaker Joe Romeiro has released yet another awesome white shark (Carcharodon carcharias) video. “Battle Scars” focuses on my favorite shark on the planet, “Cal Ripfin” (aka “Shredder”). Cal is a regular around Isla de Guadalupe in the fall months and is easily recognizable by his distinctive dorsal fin damage (as well as his many other “battle scars”).

Kudos to Joe for putting together another great video!

Shark Diving International recently posted video footage of a white shark (Carcharodon carcharias) feeding on a northern elephant seal (Mirounga angustirostris) off of Mexico’s Isla de Guadalpue. White shark predation events on pinnipeds are somewhat rare around the island, so this footage is definitely worth a look.

Here’s another Shark Week 2011 promo from DiscoveryNetworks YouTube Channel. The clip is taken from the program “Great White Invasion” and features Chris Fallows free diving off Mexico’s Isla de Guadalupe with multiple white sharks (Carcharodon carcharias). Guadalupe is know as one of the premiere locations for viewing great white sharks during the fall months.

Shark Week 2011 programming premieres July 29 at 9pm on the Discovery Channel.

Lawrence Groth has posted some impressive great white shark footage from Isla de Guadalupe to his YouTube Channel which was filmed from what the video description calls the SPSC (Self-Propelled Shark Cage). Several of Guadalupe’s “regulars” can be seen in the video, including Lucy, Cal Ripfin (aka Shredder), and Zapata (aka Bruce).

According to the Great White Adventures website, the SPSC was designed for use by Film and Documentary crews.

From National Geographic:

On this episode, the crew has reached their last days at Guadalupe Island, and want to make the most of it. They catch one more female great white, Annika, and Dr. Domeier hopes that a blood sample from her will complete his Guadalupe breeding ground research. They also wrangle Apache, a male, a fighter, and their biggest shark to date. The record-breaking shark, measured 13 inches longer than their previous record-holding white shark capture, weighs approximately 4,225 pounds.

“Shark Men: Biggest and Baddest” premieres Sunday at 10pm ET/PT on the National Geographic Channel.
