Indeed, cnidarians are considered as the largest phylum of generally toxic animals.

This suggests a degree of partner specificity that may limit the adaptive potential of certain cnidarians to increased ocean warming.

This suggests that free-living Symbiodiniaceae may provide a supply of potentially "new" thermotolerant strains to cnidarians following a bleaching event.

The adaptive bleaching hypothesis postulates that cnidarians that can form a stable symbiosis with thermotolerant Symbiodiniaceae strains may cope better with increasing seawater temperatures.
5
The ability of some symbiotic cnidarians to resist and better withstand stress factors that cause bleaching is a trait that is receiving increased attention.
6
The lack of a coordination is consistent with previous work on many cnidarians where coordination between actively pulsing polyps and medusa has not been observed.
7
Coordinated pulsing has not been observed in many cnidarians (jellyfish, anemones, corals), as is the case for the xeniid corals considered in our corresponding paper.

In Cnidarians, cnidoblast cells contain organelles called cnidocysts, which are believed to be the product of an extremely complex regulated secretory pathway.
