Hidden life stories in fish ears
Fossilized fish ear stones – known as otoliths – can reveal far more than previously thought. In a recent study, a team of palaeontologists from the University of Vienna demonstrated that a refined electron microscopy technique can make even the finest growth rings visible. These microscopic structures may reflect a fish's life story down to just a few hours – an important breakthrough for understanding fish growth, biomineralization, and environmental change across millennia. The study was recently published in Limnology and Oceanography: Methods.

Some more otoliths, now. Rita Almeida looks at the shape and chemistry of #otoliths from European #SeaBass. The use of freshwater habitats is not well understood. Early overlap in chemical signatures at an early life age, because they share a similar nursery ground. However, in older #fish, more individuals started clustering with freshwater #habitats. Migratory #behaviour seems to be associated with ontogeny #FSBI2025

Photographer Yvette Monahan: ‘Otoliths, or ear stones, have revealed a fascinating world of fish senses. Otoliths can serve as biological timekeepers and storytellers – much like tree rings, holding the collective memory of the aquatic world. These remarkable otolith structures hold a biochronology– a map of life experiences embedded and made visible within their physical forms’
