If you read the passages you posted you will see that it is NOT referring to his ‘tail’ but to another appendage.

[Sopater]

When I read the passages, all of the English ones specifically use the word "tail".

The Hebrew word which was translated as "tail" is זנב (zânâb ).

Strong's dictionary says: the tail (literally or figuratively): - tail.

Brown-Driver-Briggs’ Hebrew Definitions says: tail, end, stump

If you're seeing a reference a specific appendage other than a tail that might belong to a hippo, elephant or rhino, it's because you want it to be that appendage. Shame on you. ;-)
