A tagged white shark like this one, ended up in the gill net of Mozambique fishermen.

OCEARCH is reporting that a female white shark tagged in South African waters was killed after being caught in a gill net in Mozambique waters. The shark, nicknamed “Brenda,” was tagged earlier this year in Mossel Bay by OCEARCH along with a team of South African researchers.

According to OCEARCH the shark’s carcass was harvested. Its meat was given to a local village, while its fins were sold. Eyes on the Horizon, a Mozambique NGO, were able to recover the SPOT tag.

Could focusing on white sharks’ processing of visual stimuli lead to a more effective repellent?

The Telegraph reports that new studies involving the dissection of shark brains has indicated that a large portion of the white shark’s (Carcharodon carcharias) brain is associated with visual input. Researcher Kara Yopak of the University of W. Australia believes that understanding how the white shark’s brain functions could be vital to developing repellents that are based on visual stimuli.

Existing repellents tend to target the ampullae of Lorenzini, which are electroreceptors used by sharks to detect electrical fields in the water. According to Yopak, these types of repellents failed to deter attacks from white sharks in all cases. Yopak believes that focusing on the effects of neurobiology on white shark behavior could help to develop a more effective deterrent.

The past few days have seen quite a few photos either misrepresenting the effects of Hurricane Sandy or just flat-out faking them. Some gullible news outlets have been running with photos that appear to show a shark swimming through a flooded neighborhood in New Jersey. A few of the photos have already made the rounds during other major storms, but there are a couple of new ones that claim to show sharks swimming around a New Jersey that are brand-new exclusives to Hurricane Sandy.

The photos apparently originated as a hoax on a Facebook page and have since been circulated by some as genuine.

The Atlantic has a fairly extensive page that debunks or verifies some of the photos from Hurricane Sandy that have been going viral, as of late.

While Hurricane Sandy is definitely presenting some real-life dangers to many, sharks are pretty far down on the list of worries that those affected by the storm are dealing with.

A “Paddle-Out” was held Sunday (10/28) to honor a California man who was killed in a tragic shark attack last week. The victim was remembered as someone who “loved the beach and surfing,” and “embraced those around him with a smile and a mellow attitude” according to a Lompoc Record article.

The surfers who participated in the memorial paddled out about 100m and formed a circle, where family members, transported by boat, briefly spoke. The surfers then each dropped a flower into the water in a sign of remembrance.

YouTube user Melissa Galieti captured this footage of what is described as a 10-foot (3m) great white shark (Carcharodon carcharias) feeding on a Pacific harbor seal (Phoca vitulina richardsi) off La Jolla, California. The footage was shot on October 2, 2012.

It’s unclear from the video how large the harbor seal involved was, as the carcass had already been fed upon to some extent prior to what is seen in the video. Preying on pinnipeds (seals and sea lions) is a behavior generally associated with larger white sharks. The shark seen in the video would likely be considered on the smaller end of the scale, in terms of size, of white sharks that target pinnipeds as prey items.

Vimeo user Surya P recently added this video, which features some nice whale shark (Rhincodon typus) footage filmed in Indonesia’s Cendrawasih Bay. The video includes a lot close-ups, along with some footage of a couple of whale sharks grabbing a snack from fishing nets.
