  • Passionate about Thresher Sharks in the Philippines | Biology Online Blog
    two glorious months diving and studying these magnificent sharks One of the important things to remember about working on an upstanding Conservation project is that your work is not glamorous you don t do it to get the glory photo of you with insert your dream animal here If you re doing research you do the dirt work the essential data collection that adds to the bigger picture and contributes to data that can be used to lobby for the protection of the dream animal Photo credit Steve De Neef The reason you can see Thresher Sharks in Malapascua is the presence of an underwater seamount surrounded by deep dark waters that houses coral reefs that in turn are the habitat for several reef fish that provide cleaning services to large parasite ridden fish The Threshers along with the occasional Grey Reef Shark and Manta Ray rise from the depths to visit the seamount to rid themselves of parasites Cleaner wrasse and Moon wrasse swim in their cleaning stations salons if you will until one of these elasmobranchs enters and displays a specific behaviour The Thresher Shark circles lazily round and round whilst the wrasses dart up and bite off the parasites The Grey Reef shark shakes it s tail feather across the cleaning territory to show the wrasse it s not about to eat them The Manta maybe the most graceful of all sea creatures hovers above the cleaning station flicking its wings ever so slightly to stay in place Photo credit Steve De Neef There is a substantial diving industry built around the presence of these animals Up at the crack of dawn divers head out and descend on the shoal to catch a glimpse of the sharks and if they are extremely lucky a Manta Whilst there have been several policies implemented to prevent divers from impacting the sharks whilst they clean you can imagine that a wall of bubbles from a row of divers might be a turn off In addition inexperienced divers cannot control their buoyancy and hover for the whole dive and end up kneeling on the reef to stay put This has resulted in damaged corals and in some places the reef has been reduced to rubble or even sand The presence of the diving industry no doubt brings the plight of the Thresher Shark to a global audience It raises awareness breeds emotional connection and encourages a passion for the sharks and their environment in a way that nothing else can But there should always be a balance the act of raising awareness should not significantly damage the animal or its habitat Otherwise what s the point Photo credit Steve De Neef The conservation project aims to study the natural cleaning behaviours and the impacts of divers on the reef and cleaning behaviour The extent of the disturbance is unknown and successful managing strategies should be based on robust scientific data The project aims to find out Everyday we deployed a video

  • Can dogs really recognize human emotional expressions? | Biology Online Blog
    s ability to recognize sadness There were also news reported about dogs saving their owners life from an attempted suicide One of them was a dog who was aptly regarded as a hero for successfully preventing a troubled 13 year old girl from committing suicide in Chengdu Sichuan province in China The yellow haired dog named Roman dragged the teenage girl by her shirt when the girl was nearing the edge of the roof of a three story apartment building and attempting to jump The canine kept pulling her away from the edge until firemen were able to rescue her 2 According to LifeWithDogs site dogs can even take it a step further and potentially diagnose rare and fatal diseases that their owners carry such as cancer In an article by published by Melanie of LifeWithDogs a dog actually was able to diagnose cancer and save the life of its owner These stories may not be enough proof of the ability of dogs to recognize human emotional expressions However Ludwig Huber and his research team in University of Veterinary Medicine Vienna s Messerli Research Institute recently published their findings in the Cell Press journal Current Biology 4 where they claim that their discovery is the first solid evidence implicating the ability of dogs to detect and discriminate between happy and angry human faces Not only were they able to observe the ability of dogs to discriminate faces of people they know well but they were able to do so on those they had not seen before Nevertheless their findings are not yet thorough and therefore would require further studies to gain more insight into such ability of dogs to recognize certain human emotional expressions Sources 1 Khuly P 2011 Why Does My Dog Always Lick Me VetStreet com Retrieved from
