As the sponge grows it frequently attaches itself to small molluscs such as the young of Vivipara bengalensis, which finally become buried in its substance and thus perish.
I have found specimens occasionally on the shell of Vivipara bengalensis, but they are much more common on the leaves of Vallisneria spiralis.
The best Mollusks for this purpose are the Limnaea, the Planorbis, the Physa, the Vivipara and some of the "pigmies" just mentioned.
Another handsome shell belonging to this group is the Vivipara contectoides, which is about an inch in length and is encircled by several color bands.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "vivipara" in a variety of sentences. We hope that you will now be able to make sentences using this word.
