YouTube user ruste13, recently posted the above video, which shows a pair of dogs “rounding up” several shark near the shore. At one point, one of the dogs decides to take a dive and, according to the narrator, bite one of the sharks. While the dogs seem to be having a pretty good time, it looks like the sharks dispersed after the dog went for a dive.

According to NBC San Diego a diver was physically unscathed after being bitten by what is believed to be a sevengill shark (Notorynchus cepedianus). Justin Schlaefli was spearfishing off La Jolla when the incident took place.

Schlaefi said the shark bit his calf three times. He believes the shark was after a calico fish on his stringer. After punching the shark, Schlaefi said it swam toward one of his diving companions, who attempted to shoot it with his spear gun.

While his wetsuit did sustain puncture marks from the bites, Schlaefi himself did not sustain any physical injuries.

Sand tiger sharks are among the protected species that regulations prohibit removing from Delware waters.

According to a Delmarvanow.com changes to Delaware’s shark fishing regulations are set to go into effect on June 11, 2011 in attempt to discourage the targeting of protected species. The new regulations state:

It shall be unlawful for any hook and line fisherman to remove from the water sandbar shark, or any other species of shark when prohibited from harvest under §3541.

Delmarvanow.com quoted fisheries administrator for Department of Natural Resources and Environmental Control’s Fish and Wildlife Division, Craig Shirey, as saying, “if you have to get out there in the water with the shark to let it go, then maybe it will discourage people from fishing for them.” DNREC fisheries scientist, Scott Newin, said that the current regulations need to be defined more clearly and also noted that the public needed to be better educated about how to properly handle hooked sharks to minimize injuries to the animals.

Violations of the new shark fishing regulations would carry fines of $25-$100. For more information check out Delaware’s 3541 Atlantic Sharks regulations.

NBC Philadelphia is reporting that a boater alerted the Coast Guard that he saw a 12′ great white shark (Carcharodon carcharias) off of New Jersey’s Island Beach. The boater reported that the shark was at least 200 yards from the shore, but “not too far” from the bathers at the nearest beach. Lifeguards were alerted after the report, but no beaches were closed as a result. The boater who reported the sighting was the only witness to report seeing the shark.

While some remain skeptical of the reported sighting, due to the fact that white shark sightings in the area are rare, it would not be out of the realm of possibility for a white shark would be in the area this time of year. Tracking data has shown that white sharks migrate up the East Coast as summer approaches and water temperatures rise.

For some reason, this old clip of Valerie Taylor hand-feeding a great white shark (Carcharodon carcharias) has recently been making the rounds online this week. The footage in the clip is from the Australian Geographic documentary “Shadow of the Shark.” The clip was posted on YouTube almost two years ago, but this week it has had a surge in views and has been featured on few high-traffic blogs, including Comedy Central’s Tosh.0.

The video clip shows Taylor feeding fish to a white shark and at one point patting the shark on the snout. Taylor says that she felt like she had an “understanding” with this particular white shark and thought that they could get along “quite nicely.” Taylor does point out that she did not have the same feeling with some other white sharks.

It should go without saying that white sharks are wild animals. One could make the argument that this footage and other footage of humans interacting with sharks help dispel the myth that sharks are simply “mindless killing machines.” However, the title of the YouTube video claiming that Valerie’s hand-feeding is “evidence” that great white sharks are “peaceful” is nothing short of anthropomorphism.

It should also be noted that Valerie Taylor (along with her husband Ron) have a great deal of experience being around white sharks. Hand-feeding a wild animal isn’t a wise idea for the average Joe/Jane…in other words, “kids, don’t try this at home.”

Austin’s KXAN reports that a 22-year-old woman who was bitten by a shark in Christmas Bay was treated and released from a Galveston hospital and does not expect to have any permanent physical damage.

The shark bite occurred on Monday at at a beach on Follet’s Island, Texas. Kori Robertson was in waist-deep water when she felt a “jerk” on her leg. Upon exiting the water, the woman discovered bite marks on her upper right leg.

According to the KXAN report, doctors believe the woman was bitten by a bull shark (Carcharhinus leucas).

A Long Island beach was closed yesterday due to multiple shark sightings. According to a CBS 2 report, a “pack of 18-foot sharks” was sighted “dangerously close” to the shore of a West Hamptons Dunes beach. While the report notes that some of the eyewitnesses thought the sharks were thresher sharks (Alopias vulpinus), the dorsal and caudal fins in the video do not appear to be consistent with that of common thresher sharks.

While I’m no expert on shark identification, the dorsal fin seen in the video looks more representative of a basking shark (Cetorhinus maximus) to me. If anybody can identify the sharks based on the footage, feel free to share your insight in the comments section.

On a related note, CBS 2 also reports that a seal carcass was found on the beach this morning. A connection between the seal carcass and the sharks is being investigated. (Basking sharks are filter feeders and don’t eat or attack seals.)
