密河鳄

创造深潜最高纪录的是这个偶尔会入海的:密河鳄,达18米,咸水鳄的纪录是15米,其他鳄可能是大多数栖息地水都不深,没什么突出纪录,鳄鱼可能可以潜得更深,当然这须要更多数据。

在佛罗里达群岛海里发现的这条密河鳄,就是创造18米的纪录者。密河鳄不具备生活在海里的条件,但大型密河鳄可以忍耐几个小时在海里,其他鳄也可以生活在半咸水/咸水里,不过需要定期获得淡水。

This American alligator was spotted by Lazaro Ruda in 18 m of water off the Florida Keys. Note how it is partly buoyed by
the water; buoyancy issues are discussed in Chapter 4. Little or nothing is known about how deep crocodylians can dive and future
studies are awaited with interest. Alligators are not equipped physiologically to live in sea water, but large animals can tolerate it for
some hours and many alligators feed routinely in brackish or salty habitats (but they need periodic access to fresh water, as discussed
in Chapter 11). (Photo Lazaro Ruda, TheLivingSea.com)
