我看不太懂
The beach was not only able to support the weitght of a 6 tonna orca,
but with enough wiggling the cetacean could squirm its way back to the
safety of deeper water.
第二行的but大概就是but also，那主词是with...cetacean?
with +.. 当主词，是有省略什么吗?
谢谢!

with enough wiggling 的 cetacean

主词是the cetacean

看懂了，谢谢大家

可以告知这句话的出处吗？我google不到。我想跟朋友讨论这句的句子结构
