Did you know that the freshwaters of the world cover only ~0.8% of the Earth’s surface, yet are home to ~6% of its species? From a conservation perspective, it’s important to appreciate exactly what we have got before we go about identifying how to protect or manage habitat for it. It’s a challenging enough problem for scientists studying terrestrial animals, let alone those hidden beneath the surface of the water. Added to that, aquatic species often exhibit less obvious differentiation in external characteristics (ie they tend to look the same), hence the term cryptic speciation.
