SUFB 89: Sharks Found in Underwater Volcano

Speak Up For Blue Podcast

On today’s episode, Andrew discusses the important role that government plays in the sustainable management of our oceans, and details a unique marine ecosystem that may hold some keys to understanding how animals will respond to ocean acidification.

You may have heard us at SUFB discuss, on many occasions, how crucial it is for passionate ocean stakeholders (like yourself) to contact your local politicians and convey your interest in seeing ocean-based legislation passed through. Andrew recently reached out to one of his local Members of Parliament (MP) through social media, and was able to get a meeting with her which focused on the role he could play as an educated and concerned citizen in creating scientifically-sound policy. While it may seem at times like a feeble endeavor, it’s accurate to say that if any politician is going to listen to you, it’s going to be your local representative. These are people who are elected based on how they address issues passionate to voters like yourself, so they have a stake in your opinions and, more importantly, how you act on those opinions.

There is no way to make a seamless transition to our next topic, so I won’t even try. Researchers this summer obtained video evidence of a few shark species swimming in the Kavachi seamount, a hot and highly acidic marine environment that surrounds the active Kavachi volcano. These species, which include silky sharks, hammerhead sharks, and even a sleeper shark, were previously not known to inhabit areas with high levels of acidity. It’s unknown whether these sharks were just passing through or were permanent residents of the volcano’s surrounding waters, but as far as the team could tell they seemed unaffected by the harsh conditions. These types of environments with high acidity and temperatures are extreme examples of what our future oceans could look like if we don’t stop the adverse affects of climate change. Therefore, it’s extremely important that we continue to explore and study these ecosystems and the individuals living in them to get a better understanding of the biological thresholds and limits of our vital marine species.
