A tarantula being consumed by the parasitic Cordyceps fungus. When the cordycep’s fungus attacks a hosts body it gradually replaces the host’s tissue, while it’s fruit body projects in complex shapes, as seen above. Some cordycep’s species are even able to influence the behaviour of their host, for example directing their host to climb and attach to a plant before it dies, ensuring optimum temperature and humidity for the growth of the fungus, and maximal spread for the fungal spores.
