Letter to the Discovery Network

Image
To the Discovery Network: Members of our Internet shark discussion forum, SHARK-L, have been asked by your marketing representatives to help promote your famous Shark Week sequence. This letter, signed by list members and friends, is our formal response to the request from your grass roots agency, New Media Strategies, for our support of the programming. How can we support Discovery Channel when we are fighting for shark conservation, and its biggest obstacle is the monster image given to sharks by the media, including Shark Week programs? Further, some of us who have been directly involved in the production of your documentaries feel disgusted at the way that our interviews were censored and our words twisted around. Our group is comprised of scientists, researchers, educators, media companies, and many NGO's, lobbyists and others. In aggregate we represent a strong network of influence that can help or hurt the efforts of any Shark related programming or initiatives. In...

On the gestation period of the blackfin reef shark, Carcharhinus melanopterus in waters off Moorea, French Polynesia

Image
Originally published in the Journal "Marine Biology" at: http://link.springer.de   Abstract Underwater visual and photographic observations, over a four year period, monitored the presence of mating wounds on female Carcharhinus melanopterus . Mating begins in November and continues until the end of March as each female follows her own temporal cycle. Correspondingly, parturition begins in September and continues until January. Each female again mates 1.5 to 2.5 months after parturition, thus completing an annual reproductive cycle. The gestation period is 286 to 305 days, with slight individual differences. All resident sharks under observation followed this pattern. Evidence of reproductive events presented by transient females conformed with the pattern of the residents. Introduction The few studies postulating a gestation period for the reef blackfin shark Carcharhinus melanopterus have varied greatly in their conclusions. Based on an examin...

SHARKS DON'T BITE like we do

Image
Though sharks have gained a mythical reputation for being biters, their behaviour in nature is the opposite of what we would expect from the vicious animals depicted in the media. I had many opportunities to observe sharks under circumstances in which I expected them to bite, as a dog, cat, horse, or bird would tend to do. Yet they did not.  All other species, wild and tame, with whom I had the intimacy I shared with sharks, had bitten me sooner or later, either by accident or in a fit of pique; even my pet dog sometimes grabs my hand in her teeth along with the offered cookie.  Further, while the blackfin reef sharks I knew enjoyed roaming with favourite companions, I never saw them fighting with each other. They had friends but no enemies ! For years people had told me, and I half believed myself, that one evening I would be bitten and would bleed to death, or faint and drown. Since I was alone far from shore as night was falling, I could expect no one to...
