Sperm evolution across reproductive and fertilization modes

Project description

Spermatozoa are the most diverse cell type, a fact that has intrigued evolutionary biologists for centuries. So far, only studies within animal groups that vary mostly in minor (size), not major (shape) sperm design have been conducted. Consequently, this key question remains unanswered. Water bears (Tardigrada) are tiny eight-legged animals, best known for surviving extreme conditions (even outer Space!). But their spermatozoa are equally strange – tufted tails, hinged heads, no mitochondria… all the diversity needed to finally tackle the issue within a single group. This project will also brings tardigrade research into Finland, providing a source of new and charismatic creatures to inspire the next generation of scientists.
