The electric eel - actually part of a family of small electric fish mostly found in South America - stands out for its ability to generate hundreds of volts. This made it the favourite experimental subject for pioneering studies of electricity in the 17th and 18th Centuries. Professor Ken Catania from Vanderbilt University explains how using modern equipment helped unveil sophisticated ways in which the electric eel uses its high power output to kill prey.

Clams
Giant clams have evolved to become living greenhouses by growing symbiotic algae as a source of food. Professor Alison Sweeney of the University of Pennsylvania explains how we can learn about efficient solar energy harvesting from these clams. This research could lead to new types of solar panels or improved reactors for growing biofuel.
