认识“Lucy”瓜达卢佩岛的大白鲨


Instagram的 
我爱"露西", 和我'我不是指50年代流行的电视节目。"露西" is a large female Great White Shark, that is regularly visiting 瓜达卢佩岛。大多数成年女性每隔一年见一次。他们在瓜达卢佩岛(Guadalupe Island)交配,然后远离该岛,直到他们在瓜达卢佩岛怀孕约18个月后在巴哈海岸和科尔特斯海分娩。



Unfortunately "露西"没有'似乎怀孕了。 2008年,她的尾巴受了伤,很可能是被另一只鲨鱼咬伤了。她的尾巴几乎整齐,可能影响她的速度。我不知道't know if that'她这样做的原因'似乎没有怀孕,但在过去的9年中,我们每个季节都见过她。


"露西's" tail makes it very easy to identify her. Usually we identify the individual 鲨鱼 by their coloration. The transition from the white underbelly to the grey top is unique for every individual. Some people try to identify the 鲨鱼 by their scars. That is how "咬脸" got his name. The problem with scars is that they heal and if that is the only identifying characteristic you have, you would not recognize that same 鲨鱼 when it comes back the following year. Mutilations, like 露西's tail don't change and can be used in conjunction with the markings to identify her. We have a photo id database that is managed by 妮可·纳斯比·卢卡斯(Nicole Nasby-Lucas) from the Marince Conservation Science Institute, with over 220 individual 鲨鱼 in identified.

If you are coming out on one of our "科学"探险,你'll get a chance to learn how to identify these 鲨鱼 来自妮可本人。您还将获得完整的带照片的ID数据库,这样您可以识别遇到的所有鲨鱼和真正酷的鲨鱼,然后可以识别在电视上看到的鲨鱼。当您在电视上看到一条鲨鱼并意识到这是一个从您的脸游到几英寸远的人时,它将有多棒 瓜达卢佩?




即使她的尾巴使她放慢了脚步,她似乎也以其他方式保持健康。她肯定得到了足够的食物,并在所有鲨鱼中占有一席之地。 岛。 露西 is a very curious 鲨鱼 and she swims very close to the cages, making eye contact with our divers as she is gliding by slowly.


I hope to see 露西 when we return in the fall. I do have mixed emotions though. While I would love to see her, it would of course mean that she didn't get pregnant again last season.
