Enviado por Pinguim Paulo Guilherme - 10h00m Turismo ajuda a preservar mares e tubarões nas Bahamas Muitos dizem que para se preservar é preciso conhecer, admirar, gostar. Os tubarões, por exemplo, são animais de maturez sexual tardia (alguns chegam a 15 anos para entrarem em idade reprodutiva) e outros tem gestação de mais de dois anos, gerando um filhote de cada vez. A melhor, e única na verdade, forma de se preservar estes magníficos animais é garantindo-se seu meio ambiente saudável, mares e oceanos, e moratória total na pesca. Não concorda? O chamado eco turismo vem se mostrando no mundo como a única opção financeiramente viável para preservação de diversos ambientes que sofrem depredação por motivos econômicos, como os mares com a pesca e as florestas com o desmatamento. Então na mesma linha de turismo para conscientização e preservação, a Scubalab, parceira do Projeto Divers for Sharks, lança uma expedição especial para estes animais. Abraços e até a próxima, Pingüim Contatos: 23h45m

Partner organization Some 220 bottlenose dolphins (Tursiops truncatus) are living in the Croatian part of the Adriatic Sea. Its small size makes this population vulnerable even to minor disturbances of the ecological balance. In 1999, GRD founded the project to "Save the Last Adriatic Dolphins" together with veterinary faculty members of Zagreb University. The Croatian team members have been actively engaged in dolphin conservation for decades. What We Do Dolphin Adoptions
Cetacean intelligence
Cetacean intelligence refers to the cognitive capabilities of the Cetacea order of mammals, which includes whales, porpoises, and dolphins. Brain size[edit] Brain size was previously considered a major indicator of the intelligence of an animal. However, many other factors also affect intelligence. Sperm whales (Physeter macrocephalus) have the largest brain mass of any extant animal, averaging 7.8 kg in mature males.[5]Bottlenose dolphins (Tursiops truncatus) have an absolute brain mass of 1500-1700 grams. The discovery of spindle cells (neurons without extensive branching, known also as "von Economo neurons", or VENs) in the brains of the humpback whale, fin whale, sperm whale, killer whale,[15][16] bottlenose dolphins, Risso's dolphins, and beluga whales[17] is another unique discovery. Brain structure[edit] Dolphin brain stem transmission time is faster than that normally found in humans, and is approximately equivalent to the speed found in rats. Problem-solving ability[edit]
Beluga whale 'makes human-like sounds'
22 October 2012Last updated at 12:02 ET Beluga whales are known as "canaries of the sea" because of their frequent, high-pitched calls Researchers in the US have been shocked to discover a beluga whale whose vocalisations were remarkably close to human speech. While dolphins have been taught to mimic the pattern and durations of sounds in human speech, no animal has spontaneously tried such mimicry. But researchers heard a nine-year-old whale named NOC make sounds octaves below normal, in clipped bursts. The first mystery, though, was figuring out where the sound was coming from. When a diver at the National Marine Mammal Foundation in California surfaced saying, "Who told me to get out?" The whales are known as "canaries of the sea" for their high-pitched chirps, but while a number of anecdotal reports have described whales making human-like speech, none had ever been recorded. Once they identified NOC as the culprit, they caught it on tape. In short, the mimicry was no easy task for NOC.

Echolocation is the process of detecting and identifying objects by emitting sounds, such as the broadband clicks used by dolphins, and listening to the echoes returning from objects reflecting those sounds. A recent discovery we made is that dolphins appear capable of directly perceiving the shapes of objects through echolocation. Prior to this finding, it had been generally assumed that dolphins learned to identify and recognize objects through echolocation by a process of associative learning-by comparing the echoes returning from targets with the visual appearance of those targets. Instead, our work has shown that echolocation can yield an immediate perception of the shapes of objects without any intervention by associative learning. We established this finding by asking the dolphin to inspect an object inside of a visually opaque box, using echolocation alone, and then to find a match for that object from among two or more objects inspected through vision alone.

Operação em curso para salvar centenas de golfinhos encalhados em Cape Cod
Centenas de golfinhos estão a dar à costa em Cape Cod, perto de Boston, na costa Leste dos Estados Unidos, desde a semana passada. Dezenas de peritos e voluntários já conseguiram salvar 300 golfinhos encalhados nas águas da baía de Wellfleet, mas o trabalho ainda não acabou. O arrojamento dos golfinhos na costa a Sul de Boston já dura há sete dias, disse esta manhã ao PÚBLICO o porta-voz do IFAW, Michael Booth, por email. Ontem, membros do IFAW (International Fund for Animal Welfare) usaram equipamentos subaquáticos dotados com sonares e embarcações para tentar orientar os golfinhos para fora das águas do porto de Wellfleet. Segundo o jornal The Boston Globe, dois animais morreram pouco depois de terem encalhado nas águas pouco profundas do porto. Um morador de Wellfleet, Gary Burgess, contou ao jornal Cape Cod Times que ontem de manhã descobriu seis golfinhos perto do rio Herring, presos no lodo. O trabalho ainda não acabou.
