A sad story of the demise of a rare whale, possibly due to man's intervention
Cuvier's Beaked Whale Skeleton的点评
点评:Wednesday 17th June we visited the town of Gran Tarajal which is located on the south-east coast of the Island.
Having walked along the Promenade we found ourselves outside the gates of the Port.
It was here that we saw the skeleton of Cuvler's Beaked Whale outside the gates of the Port. The bones are held together with metal bolts and wire and is supported by metal rods and mounted on a blue painted concrete column.
Alongside the skeleton there is an information board that provides the following information about it:-
"Senda de los Cetáaceos - The natural skeleton you are looking at belongs to a Cuvler's Beaked Whale that was found stranded lifeless in April 2005 at Rogue Negro (Tuineje) in an area near the Entallada light house lt was an adult female measuring 5.5 metres. This species has been subject to significant mass strandings. The investigation of mass strandings in 2002 coinciding with military manoeuvres led to a ban on military sonar within a 50 nautica mile perimeter around the Canary lslands in Spain in 2004 .
Beaked whales measure between 4 and 10 metres in length. They are dlstributed throughout the oceans, although the true distribution of many species is largely unknown. Oceanic habits and evasive behaviour mean that sightings of live animals are rare. Beaked whales are some of the least known creatures on the planet and in some cases have never been seen at sea.
It is possible to determine the species, sex and age of a beaked Whale by the shape and location of the single pair of teeth in its jaw. lts diet is based on squid and crustaceans that it catches at depths of more than 1,000 metres. It can remain under water for up to 2 hours without coming up for air
Know, protect and conserve the sea and its biodiversity".

沿着海滨大道漫步,我们来到了港口大门外。
就在这里,我们看到了港口大门外的库氏喙鲸骨架。这些骨骼用金属螺栓和铁丝固定在一起,由金属杆支撑,并安装在一个涂成蓝色的混凝土柱子上。
在鲸鱼骨架旁边有一块信息牌,上面提供了以下信息:
“鲸鱼搁浅处——您现在看到的这具天然鲸鱼骨架属于一头库氏喙鲸,它于2005年4月在罗格内格罗(图伊内赫)附近的恩塔利亚达灯塔附近被发现搁浅死亡。这是一头成年雌性,体长5.5米。该物种曾多次发生大规模搁浅事件。2002年,由于军事演习,大规模搁浅事件的调查导致西班牙于2004年在加那利群岛周围50海里范围内禁止使用军用声呐。
喙鲸的体长在4到10米之间。它们分布于各大洋,但许多物种的真实分布范围仍然未知。由于它们在海洋中的生活习性和躲避行为,人们很少能见到活体喙鲸。喙鲸是其中最不常见的物种之一。”地球上已知的生物中,有些甚至从未在海洋中被发现过。
通过喙鲸颌骨中那对牙齿的形状和位置,可以确定其种类、性别和年龄。喙鲸以鱿鱼和甲壳类动物为食,捕食深度超过1000米。它可以在水下停留长达2小时而无需浮出水面呼吸。
