Rose bushes have thorns.
After stomping through the weeds and thorns, we took our clothes off underneath the water tower and began making love in broad daylight.
However, experiments in which crown of thorns larvae have been suspended in cages in various parts of the tropical ocean have not supported this idea.
Care is taken to leave the thorns intact, and the thick end of the stalk is broken off.
None of the studied plant species had spines or thorns.
In this literature, it is rare to find some roses blooming amongst the thorns of negative case studies.
The major defensive mechanisms of acacia are mechanical (thorns) or qualitative-defence chemicals (cyanogenic glucosides) that are apparently more effective against vertebrate than invertebrate herbivores.
