Shark in a Trance

I came across this on Yahoo News and couldn't resist posting it b/c I think it's inspiring that she uses this technique to do good things for sharks. The other story that it links to is sadder.

A diver in the Caribbean balanced a vertical 10-foot shark thanks to her unusual ability to put it into a trance. To create the state, the Italian diver rubs the ampullae of Lorenzini, the name give to hundreds of jelly-filled pores around the animal’s nose and mouth. She has used the technique to remove parasites and fishing hooks caught in shark mouths. It has been a big week in shark moments, after this photo of a Cyclops shark also made the rounds.

White Shark Evidence off West Vancouver Island

The great white shark (Carcharodon carcharias) is one of the largest and most revered sharks in our waters. In Eastern North Pacific waters white sharks range from Alaska to Mexico, but are most common off the California coast. A very low number of white sharks have been identified in Pacific Canada, a total of 14 were recorded between 1961 and 2004. However, we have received 8 unconfirmed sightings of white sharks in waters off the west coast of Vancouver Island from 2000 to the present day. These white shark sightings were made by fishers and surfers. Sighting descriptions are usually of “smaller” white shark (3 to 4 metres) suggesting juvenile white sharks. Recent satellite tagging research off the California coast suggest that juvenile white sharks spend a lot of their time in nearshore coastal waters, most likely looking for prey.

The only photo evidence we have received to date of white sharks are from injured or dead animals. In 2005, Tanya Dowdall found a Harbour Porpoise (Phocoena phocoena) washed up on MacKenzie beach in Tofino. The bite was later confirmed by the late Aiden Martin from ReefQuest Centre for Shark Research as an inexperienced juvenile white shark bite. In 2008, a local marine mammal biologist, Wendy Szaniszlo, photographed a Stellar Sea Lion (Eumetopias jubatus) with a large bite on a pinniped haulout in Barkley Sound. Ralph S. Collier from the Shark Research Committee confirmed the bite as one made by a white shark. Ralph cited four points that confirmed a white shark attack: 1) location of bite on the sea lion, 2) accompanying individual tooth insertion impressions, 3) perimeter of exposed musculature and accompanying tissue, and 4) “interspaces” between the individual impressions. To ease the minds of local swimmers and surfers there has never been a white shark attack recorded in Pacific Canadian waters.

If you have any past or recent shark sightings in the waters off British Columbia we want to hear from you. Email your sighting details to shark_reports_bc@yahoo.ca

Basking Sharks

Basking sharks (Cetorhinus maximus) are the world’s second largest shark, reaching up to 12.2 metres long. These gentle giants are filter feeders and feed on tiny animals called plankton. Basking sharks were once abundant in BC waters and the population was thought to migrate between waters off California and BC. However, numbers greatly declined between 1940 and 1970 as sharks were entangled in fishing gear, part of a directed fishery and targeted in an eradication program. By the 1970s basking shark sightings were rare along the coast of BC, estimated that the decline from pre-exploited numbers exceeds 90%.

Basking sharks were listed as endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 2007. In March 2010, the basking sharks were scheduled under the Species at Risk Act (SARA) and now receive legal protection. This protection makes it illegal to kill, harm, harass, and disturb these sharks. In addition, experts are working towards a recovery strategy over the next year that will outline research and actions that need to be achieved to ensure the recovery of these gentle giants.

Do you want to help basking sharks on their road to recovery? Well here’s what you can do! Fisheries and Oceans Canada are leading a sightings network for basking sharks. If you see a basking shark in BC waters go to the following website to report your sighting http://www.pac.dfo-mpo.gc.ca/SharkSightings or call the shark line toll free at 1-877-50-SHARK (1-877-507-4275).

An adventure with a Salmon Shark

Here is a very nice story and we commend Ken and Kim for their shark-saving efforts! You can see in the video that one has to be very careful though--the teeth are very sharp and the small jaws powerful. That didn't stop anyone in this rescue though! Running exhausted seabirds over to the calm inlet side is common practice for us--I can't believe I have never thought of doing this with Salmon Sharks! Great idea and one I will employ with caution if I ever get the chance. It would be cool to know where she(I didn't see any claspers) went after her rescue from stranding. Thank you Ken and Kim.

Dear Editor,

We visited your lovely town of Tofino October 15 to 17 and had an encounter with a shark. We were told it was a salmon shark, and rare for the area. We found him washed up on Chesterman Beach, exhausted, and sure to die.

Even the surfers tried to carry him out past the waves, but to no luck. So my hubby picked him up, put him in our trunk and we zipped over to the inlet side and tried to revive him.

After about 15 minutes, he came around. He swam around in the little bay, then headed out to the currents of the inlet, and hopefully back out to the ocean.

Just thought we may share this experience with you.

Ken and Kim Foreman,

Westbank, B.C.
