Riftia Pachyptila: A Brief Introduction

The world is a symphonic orchestra.” The endemic giant tube worm, Riftia Pachyptila, is a strange instrument. One of the most studied deep sea species; it survives in habitats of extremes in pressure, temperature, oxygen and light (Zal et al., 1998.) Namely, the worm has no mouth or digestive system and instead relies on sulphide concentrations in the surrounding fluid. Every aspect of anatomy is a further evolutionary step towards creating an organism specialised for its environment, this blog aims to study these specialisations within R. pachyptila.
