There is a large pool of interesting defense mechanisms in all ecosystems, however this blog will focus on those found in marine systems. This is because these species have not received attention like those of the terrestrial systems, and new incredible species are uncovered almost periodically.
This blog is not intended to provide an overview of all defense mechanisms of all marine species. But, with a heavy load of bias, show selected few species, certain defense mechanisms they possess, and their evolution.
