Rose poem about animals

A word- fish is not at ease with carpentry
it uses its natural weapon for hunting other fishes
which is ok for us when lost on a raft
in the middle of the ocean.

A blue whale is too big to be used as circus
entertainment there not a tent big enough to house it.

Relatively expressed It is about an aquarium, size.
Onlookers would be drenched when it turns around
Simply because they have no big umbrella.
extremities of this sort should be left in the ocean
