There Stephanie and I learnt a ton of information about the conservation efforts, biology and history of Giant Sea Turtles!<\/p>\n
First off, they are massive; <\/strong>some adult species budding over two metres in length. Second, they are old; <\/b>at live-spans estimated at 100 years they are some of the oldest creatures around.<\/p>\n Five of the seven species of sea turtles are found in Brazil, which are distinguishable by the plates on their shells and comprise of: Loggerhead<\/em>, Olive Ridley, Green, Leatherback<\/em>, and Hawksbill<\/em>. All of which are threaten with extinction<\/strong> and the latter two being critically endangered<\/strong>.<\/p>\n Sea turtles differ from their land-loving relatives by their developed flippers and unique spawning process. From the months of September to March, female turtles migrate to the Brazilian shorelines to lay and bury golf-ball sized eggs\u00a0 within the sand, where they incubate for 45-60 days.<\/p>\n Fun fact, during this time the temperature of the sand actually determines the sex of the turtle.<\/p>\n Turns out\u00a029\u00b0C is the magic number<\/strong>.<\/p>\n Warmer?<\/strong><\/span> It\u2019s a girl<\/strong>!<\/span><\/p>\n Colder?<\/strong> <\/span>It\u2019s a boy<\/strong>!<\/span><\/p>\n When incubation is done they hatch, crawl out of the sand and scurry to the sea as fast as they can. They then go on living their juvenile lives and return again one day to those same shorelines once adulthood is reached.<\/p>\n For the past 30 years the TAMAR<\/strong> project has been very successful in the conservation of these vulnerable creatures. Back in the 1980s little was known about sea turtles, nearly all female up on the beach were killed, and all their eggs were poached\/collected. Brazil was doing nothing about it at the time but international pressure was rising. A group of oceanography students came together, surveyed the shorelines and wrote a reported to the\u00a0government.\u00a0Since then, TAMAR has grown to 23 stations, with the main national headquarter in Pria du Forte<\/strong> where we visited.<\/p>\n Working with local communities their conservation efforts range from:<\/p>\n Thanks to their efforts, within the past 30 years they have completely changed the mindsets of how turtles are managed and now only 2% of them are being poached, since they local communities realize: a turtle is<\/strong> worth more alive than dead<\/b>.<\/p>\n As considerable as the conservation effort from the TAMAR project have been, there are still many threats to these endangered species, especially moving toward the 21st<\/sup> century.<\/p>\n With coastal development and new resorts swelling in Brazil, beaches are becoming more crowded<\/b> and nests are increasing becoming threaten and disturbed. This is a crucial responsibility of TAMAR, where they monitor the beaches between 20:00-2:00 and mark the turtle nests. Once marked they put protective nets on top and monitor them, and if in a high traffic area, relocate and transfer to the beach research centre to incubate until they are ready to hatch and be returned to the sea. In the meantime valuable information such as skin, blood, and scale samples are taken to help track these turtles\u2019 health and abundances.<\/p>\n Artificial lighting from these developments and climate change also menace the turtles because of their heat sensibility (remember the 29\u00b0C magic number<\/b>). Lighting disorientates the baby turtles and gets them lost<\/strong> and dehydrated<\/strong> when they head for the sea. It also falsely heats the sand. Likewise, climate change will have a broader effect on the ocean temperature, where it can skew the equilibrium and distribution of males and females within the surrounding water.<\/p>\n It\u2019s always a treat to be able to go to another country and learn about their unique inhabitants. And to find an organization doing such a successful job at the conservation of these creatures makes me impressed and inspired. Organizations like this are important to protect those that can\u2019t for themselves, especially because it is usually our society who caused the harm in the first place.<\/p>\n If you are interested in learning more about sea turtles or the TAMAR project be sure to check out their website at\u00a0http:\/\/www.tamar.org.br<\/a>.<\/p>\n![\"TAMAR](\"http:\/\/farm9.staticflickr.com\/8203\/8245244701_bc3cc68e03_b.jpg\")
