夏威夷和尚密封

On a group of islands far, far away lives one of the most endangered mammals in the world.

Residing only in the most isolated island chain on Earth, the夏威夷和尚印章((Monachus Schauinslandi) calls paradise home. With a population estimated to beless than1,500只动物,夏威夷和尚印章是Hawaii’sonly地方性哺乳动物。

濒临灭绝

他们最接近的亲戚是地中海和尚印章,最后的人口(少于400只动物)在希腊小岛和灭绝的加勒比和尚海豹(1952年)中幸存下来。

这些可爱的生物从孤独的天性和头部上的皮肤褶皱中获得了褶皱,可以在夏威夷群岛的沙滩和熔岩海滩上找到,在阳光下午睡。

Hawaiian Monk Seal

On the main Hawaiian Island, the seals are given priority beach treatment. When seals are seen onshore, they are surrounded by bright yellow caution tape so that tourists do not disturb their slumber.

Physiology & Threats

夏威夷和尚印章是Phocidae家族的一部分或真正的印章。他们没有外耳,无法旋转自己的后部肢体下方的后方,因此,他们没有像耳朵的密封堂一样将自己的脚伸入土地上,而是从侧面到另一侧向弯曲到岸上的身体。

成人海豹长七到八英尺;女性稍大。

鲨鱼是和尚海豹唯一的天然捕食者,尤其是在夏威夷西北群岛,鲨鱼对少年和尚海豹的死亡率很高。Humans also pose a threat.

污染,尤其是废弃的钓鱼线和网状,可能会导致纠缠。在1800年代和1900年代,还狩猎了和尚印章,以喂水手以及其皮肤和油。这大大耗尽了人口,这导致当前人群的遗传多样性非常低。1zplay这增加了疾病可以消灭整个人口的可能性。

Recently, several diseases have shown up in the seals, including the feline parasite, toxoplasmosis, which they are likely picking up from feral cats when they sleep on the beaches. Monk seals are also threatened by ciguera, found in the fish they eat, and leptospirosis, a bacteria found commonly in fresh water in the Hawaiian Islands.

Behaviour

Monk seal mating can be very aggressive with几名男性试图与一位女性交配,有时会杀死雌性或留下容易感染的大开放伤口。如果少年和尚印章妨碍男性试图与女性交配,他们也会处于危险之中。

大多数夏威夷僧侣海豹位于西北部Hawaiian Islands,但是他们中有100多个生活在主要岛屿上,可以从大岛到考艾岛。

僧海豹以珊瑚礁鱼、龙虾、鳗鱼、地壳aceans and octopus. Originally, it was thought that they fed on the near shore reefs, but recently, thanks to a critter cam, the seals were discovered to be feeding in deeper than 1000 feet of water.

Hawaiian Monk Seal

创造Papahanaumokuakea海洋国家纪念碑, which spans the extent of the Northwest Hawaiian Islands, will help in protecting the monk seals. The Endangered Species Act and the Marine Mammal Protection Act also protects them.

The population seems to be doing well at the moment, with more and more seals being seen in the main Hawaiian Islands.

幸运的海滩游客总是有机会发现阳光下的和尚海豹。同样,夏威夷的任何1zplay潜水员水下都可能有一个海豹在水下飞行。

However, the best chance for scuba diving with monk seals is to diveLehua Rock, off Ni’ihau. Ni’ihau is a private island northwest of Kauai that cannot be visited without invitation.

但是Kauai潜水操1zplay作,例如Seasport Diverstakes divers across the channel May through September. Even in good weather these crossings can be rough, but most dive trips there result in a few monk seal encounters that can last entire dives or momentarily.

Hawaiian Monk Seal

海豹有时对潜水员的好奇心很好奇,有时它们会在非常近的气泡中游泳,模仿潜水员。1zplay1zplay他们通常看起来很好奇,反复游泳,然后再往外。1zplay潜水员绝不应该追随密封件(通常这只是吓到它们),而是让密封控制着遭遇。

Any dive that has a seal encounter makes for a great dive, but seeing the endangered Hawaiian monk seal can make it even more special!
