Marine safety officials temporarily closed access to the ocean off San Clemente's city beaches Monday morning following a reported sighting of a Great White Shark off the end of the Municipal Pier. Lifeguards prohibited people from going into the water from North Beach to Lasuen Beach at 9:40 a.m. as a precaution after a fisherman reported the sighting and verified it with a photograph. The closure was lifted at 11:40 a.m. without incident. Photograph courtesy of Zachary Harmon.

A man who was bitten by a shark while surfing off the Northern California coast over the weekend is expected to survive.

Samoa Peninsula Fire District Chief Dale Unea said the man was bitten on the upper left thigh Sunday morning near Humboldt Bay close to Eureka, KTVU-TV reported.

The man, whose identity was not released, paddled to shore and met rescue crews about 8:45 a.m. He was aided by other surfers, who wrapped his wound and kept him warm.

The injury was minor, authorities said, and the man is expected to survive.

Another surfer, Scott Stephens, also survived a shark attack in the same area last year.

While snorkeling the shallows I observed approximately 30 female Leopard sharks aggregating in the shallows at the east end of the cove. This is an annual aggregation and it is thought that the females come into the warm shallows to incubate their developing embryos.

Two great white sharks battled from Manhattan Beach Pier
A fisherman on Manhattan Beach Pier hooked two great white sharks Tuesday, one estimated to measure 5-6 feet and the other 7-8 feet.

Both sharks were cut loose after being reeled to the surface and both catches were witnessed by Eric Martin, director of the Roundhouse Marine Studies Lab and Aquarium at the end of the pier.

White sharks are protected off California and landing them is illegal.

While the unnamed angler released both specimens, and may not have broken any laws, he appears to have been walking a fine line.

"He has steel leaders, and I looked in his bucket and saw that he's using large dead mackerel for bait, so he seems to be fishing for this stuff," Martin said.

These were the fifth and six white shark battles Martin has witnessed from the pier since mid-July. The first incident became tense because the angler was insistent on gaffing and hauling his catch onto the pier. He consented to let Martin cut the line only after a heated argument and a threat to call the police.

There has been a large abundance of market-sized squid in South Bay waters in recent weeks. This could be attracting rays, small sharks and and other prey items preferred by juvenile white sharks.

"It's so weird because I've also seen two swim-bys recently, including one that involved about a 7-footer that ended up about 20 feet from a surfer," Martin said. "The surfer had no idea."

From the Shark Research Committee:

On July 20, 2011, Myung Kil was surfing at Ocean Beach, San Francisco, almost opposite Beach Chalet. It was about 8:30 AM and he had been on the water 45 minutes. The sky was clear with air and water temperatures estimated in the low 60s and 50s Fahrenheit, respectively. The ocean was calm with decent swells for good small to midsized surf. No marine mammals were observed in the area. Kil reported: “I was waiting on my board for a set, looking outbound when slightly to my left, perhaps 10 o’clock and about 25 yards away, I saw a fairly large triangle fin a good foot to foot and a half and part of the sharks brownish back exposed from the trough of an incoming swell. It was moving perpendicular to me, cruised under the incoming swell and disappeared. I don’t recall much water thrashing when the shark broke the surface. I’d seen birds dive into the ocean for baitfish previously. I waited for seconds, registering that I had seen a shark, looked at the other surfers around me then saw a decent wave to catch back to shore perhaps minutes later. The shark had a very large dorsal fin, light and water shimmered on the back end of the shark, which was visible slightly out of the swell for a moment. In the light, and water, the shark looked brownish and I would guess 8 feet in length from my perspective.”

Sighting at Steinhart Aquarium Provided by docent Gail Hurley

Collected along the Pacific Shore, these sharks are also part of our San Francisco Bay Shark Study, where we catch, tag, measure, sample for DNA and release.

AXONOMY

CLASS Elasmobranchii (sharks and rays)

ORDER Carcharhiniformes (Ground sharks)

FAMILY Triakidae (Houndsharks)

GENUS/SPECIES Triakis semifasciata,

GENERAL CHARACTERISTICS
Short, broadly rounded snout. First dorsal fin is moderately large and its origin is over the pectoral fins inner margins. Second dorsal fin is nearly as large as the first one. Anal fin much smaller than the second dorsal fin. Pectoral fins broadly triangular. Grey to bronze-grey upper body with dark saddles and dots and a light ventral (bottom) surface. Max length : 198 cm or 78 in.

DISTRIBUTION/HABITAT
Common from Oregon state to Baja California,Mexico. Prefers sandy and rock-strewn substrate near rocky reefs. Most commonly in enclosed muddy bays, including estuaries and lagoons, typically at less than 3.7 m or 13 ft depth, but ranges to 91m or 300 ft.

DIET IN WILD

Fishes (especially northern midshipman, sanddab, shiner perch, bat rays and smoothhounds), siphons of clams, crustaceans such as crabs and shrimp. Feeds heavily on fish eggs (herring, jacksmelt and topsmelt) attached to rocks and plants.

REPRODUCTION

Ovoviviparous. Litters 4–29. Young average 21 cm or 8 in at birth.

PREDATORS

Can live to at least 30 years. Part of the commercial shark fishery and very popular as a sport “fish.” Preyed upon by other sharks.

REMARKS

In San Francisco Bay, leopard sharks tend to remain in the Bay throughout the year, with some emigration during fall and winter.
Fossils of leopard sharks have been discovered in deposits dated to more than 1,000,000 years old in southern California.
