How much does climate change impact Tasmanian seahorses and how?
Climate can impact Tasmania sea horses in many ways. To understand the total impact, we need to think about not only what warmer water will do to the seahorses themselves, but also the things the eat and the things that eat them! We are not exactly sure how this will play out, but one thing is for sure: For reef-dwelling animals that enjoy colder water for any number of reasons, there is not much space to move furth south in Tasmania before hitting the inhospitable Southern Ocean.
Specifically, we have seen a nearly 60% drop from in the population of the Weedy Seadragon in Southern Tasmania. However, it is important that this could be caused by other human impacts like poaching. And some evidence does suggest sea horses will be able to adapt to warmer waters as they already live in quite a large range of temperature conditions.
