Public Aquarium update, Self decapitating sea slugs, and Underwater Acoustics with Guest host Hilary Jaffe All that and more on episode #158 of the Reef News Network!


Hilary: Self Decapitating 2 types Sacoglossen (Elysia sp.) Sea Slugs! Defense mechanism against parasites. Head pops off and regens a body in 7-22 days, the discarded body eventually dies and this process can happen multiple times.

Peter: The CoralVue Hydros Wireless Feeder is a new aquarium tool that delivers both convenience and a very attractive price.

Main Topic: Sound is all around us including and especially underwater. Over 800 species of fish use sound to communicate, to help in finding food, in reproduction displays, and to show aggression, but some of those things are being dampened. The oceans have become an increasingly noisy place and all that sound is changing how fish and other ocean animals relate to their surroundings. There have been studies looking at the impacts of sound in the wild and even in freshwater ornamental species, but there has been limited work done on ornamental saltwater species. How does the equipment we use on our tanks and ambient noise from where they are located impact them?
