Vaquita actually don’t drown when they get entangled in gillnets. Despite being able to hold their breath for long periods of time, they quickly go into a state of shock and their heart stops usually before they can escape. This is a natural, but very unfortunate, reaction that eliminates the possibility of catch-and-release in gillnet bycatch.

Yes. And their way of panicking is to roll when they impact the “invisible” net. I recommend watching http://vaquita.tv/documentary/why-are-vaquita-disappearing/ to learn more about this specific topic.

This is new to me. I know that they experience extreme stress when captured and die. So basically they panic and have a heart attack when entangled in gill nets??
