The Legend is a 4m (13') male great white shark who was first identified at Isla de Guadalupe in 2014. Unlike many of Guadalupe's white sharks, The Legend is not generally camera shy. I have had moments where I thought he was going to bump my camera's dome.

Keyser Söze, one of Guadalupe's male great white sharks, captured as he briefly turns toward the camera. While a shot like this might suggest Keyser has turned his attention toward me, it's a actually just a shot caught mid-turn, and Keyser was unbothered by my presence.

Resharing one of my favorite images of my favorite great white shark of all time...the legendary Cal Ripfin/Shredder, since every week is shark week. This guy was a rock star at Guadalupe and was likely the most photographed shark on the planet for many years in the first decade of the 2000s.

Stormy is a female great white shark, who was first identified at Isla de Guadalupe in 2016. In my encounters with her she was very curious, which made for quite a few photo opportunities.

It was mildly terrifying, because there is a $10K fine touching the whale sharks there and our dive master did not tell us they'll try to eat your air bubbles. He had a good laugh when we got back on the boat and told me they don't issue fines for "the whale sharks touching you."

I have been chased by an adult whale shark in Gladden Spit where the whale sharks come to feed on cubera snapper spawn. The air bubbles exhaled from a regulator resemble the spawn, which attracts the whale sharks. The short version is if a whale shark chases you, you're not going to outswim it.

Screaming Mimi, an adult female great white shark, approaches from below with her pilot fish companions. Pilot fish can help clean sharks from parasitic copepods. In return, the smaller fish enjoy a safe haven from some predators in the shark's presence.

It's a remote volcanic island. Not an easy trek to get to it, but it was definitely worth it when diving was permitted there.

Guadalupe great white shark Paul Walker (named after the late actor) makes a close pass in front of the camera. This individual was the shark we saw most frequently at Guadalupe during the final year (2021) that the island was open to diving.

Lucy is one of Guadalupe's most easily recognizable great white sharks, due to an injury that left her caudal fin (tail) permanently deformed. Despite fears that she would no longer be able to hunt when she first showed up with the injury back in 2007, she continued to thrive.

Relic is a sub-adult female great white shark most easily recognized by a permanent notch in her caudal fin (tail) where the upper and lower lobes meet. This notch is not visible in this shot, due to how Relic is positioned.

A reminder to everyone: while this year's number of shark incidents seems high, it's actually nowhere near the maximum NSW has had historically. In fact, for the last 5 years, shark bite rates have been similar to what they were 20 years ago.

Graph of shark bite numbers across time in NSW, Australia, separated into fatal and injured categories. Both trends are very slightly increasing since year 2000, with the greatest number of bites in 2015.

Alba the Brave, a sub-adult female great white shark, was first identified at Isla de Guadalupe in 2016. She was only about 8' (2.5m) in length at the time. Hopefully she's continuing to flourish and has grown significantly by now.🤞

One of my favorite shots of the legendary Cal Ripfin/Shredder from 2008. While it might come as a surprise, many of the great white sharks I've encountered at Guadalupe (>200 individuals) are quite shy. As this image illustrates, Cal/Shredder was not one of the shy ones.

Screaming Mimi on the rise. This female great white shark is one of the more easily identified individuals at Guadalupe due to a noticeable spinal deformity in her pre-caudal region, which is not visible in this close up. Mimi was first documented at the island in 2016.

Crazy Tryss, a sub-adult female great white shark, on an unusually "cloudy" day of the coast of Guadalupe. The waters off Guadalupe are typically clear and offer visibility sometimes over 30m (100'). However, the occasional moments of less than ideal viz do occur.

One of Guadalupe's OG great white sharks, Bite Face, all the way back in 2008. Bite Face earned his name by showing up routinely with bite marks from other sharks around his face. This is a rare shot of him without any major bites to his face.

The G.O.A.T. Cal Ripfin (aka Shredder) was one of the most photographed great white sharks on the planet in the first decade of the 2000s. His inquisitive nature presented divers with plenty of photo opportunities over the years, prior to his disappearance after 2011.

Drogin, a male great white shark, and his trusty pilot fish rising from the depths. Drogin has noticeable deformation of his primary dorsal fin, due to a 4-bolt SPOT tag that was attached to him over a decade ago. This design is no longer used in favor of less permanent options.

Stumpy is a male great white shark who is missing a noticeable portion of his primary dorsal fin. While most injuries to white sharks heal up remarkably well. Injuries to the fins are often permanent due in part to a lack of nerves and blood supply.

Jenni Walmsley, a sub-adult female great white shark, heads toward the surface. The dark patch you see under Jenni's lower jaw is a large cluster of parasitic copepods. Jenni was one of the smallest white sharks I had seen at Guadalupe when she first showed up in 2015.

A spearfish remora hitches a ride on "Monkey," one of Isla de Guadalupe's male great white sharks. The remora possessed a dorsal fin that can function as a suction cup to attach to larger animals. In return for the free ride, the remora can help keep the shark free of parasites.
