"Terrestrial pulmonate snails have got a hermaphroditic gonad producing egg cells as well as sperm cells. "
The word "got" is not necessary in this sentence.
"While most snails have a definite sex, or in case of the terrestrial pulmonates, generally are hermaphrodites, it may also happen in some species, that the sex changes during the lifetime. "
The final comma is not needed in this sentence (the one between species and that).
"The sperm cells the snail has received during several copulations, are collected in a sperm pouch"
The comma is not necessary in this phrase.
"Only later the juvenile snail managed to harden its shell by accumulating lime, to achieve a shell so hard, that the hardness of helmet shells (Cassinae, Tonnidae) or conches (Strombidae) only can be imitated with great effort by modern material research."
Another unneeded comma: the second one (between hard and that).
Also, I think you meant to say manages rather than managed (it's a common typo).
Other than those minor issues, I found the web page to be just fine. ;D

Hi there,
thank you very much for that information. I am absolutely hopeless with English punctuation, also with the division of words, but thank goodness that's usually not necessary on web pages.
By the way: The systematic name Tonnidae, Cassinae for the helmet shells has been returned to Cassidae, looks like the subfamily status was insecure anyway...
Best wishes
Robert

Punctuation can be tricky, especially commas. I help Mr Coyote with punctuation all the time in his writing. I'm lucky in that I have a good feeling for what's right. Glad to help.  |
