Reproduction poses certain problems for sessile organisms, since they cannot actively search for a mate. Many types of corals and sea urchins therefore employ a slightly different reproductive technique, releasing gametes into the water where they hopefully will join up with their counterparts to produce a new generation. The ultimate success of this method relies on synchronous spawning to ensure that the male and female gametes actually meet up. However, there is much debate as to the nature of the cue itself.
Native to South America, Red Imported Fire Ants make their homes underground. These nests are subject to flooding during rainy periods. On its own, a single fire ant Solenopsis invicta will struggle to stay afloat in water, and may even drown. Together though, these ants can form living rafts by linking their bodies together. These rafts enable a large group of thousands to stay alive for days or even months at a time.
