Discover the weird and wonderful world of sea horses with Dr James Ord! On Thu, 13 June at Culture Bar Naiiv (Vallikraavi 6). The event is FREE and in English. And there will be tea, coffee and snacks to make the discussion even cosier.

With over 33,000 species, fish represent one of the most diverse groups of animals on the planet. This diversity is well illustrated by the many different ways that they reproduce. Male fish, for example, often pitch in a lot more to the next generation than mammals typically would. This is taken to the extreme by seahorses in which males undergo full-on pregnancy. Most remarkably, both female and male fish - whether they get pregnant or not - can 'teach' their offspring before they have even been born, by means of strange mechanisms which scientists are only just beginning to understand.

Dr James Ord is a molecular biologist at the University of Tartu, specialising in non-genetic inheritance. He completed his PhD at the University of Sheffield, UK, where he studied environmental influences on reproduction and offspring in small fish.
