Documentary Overview
“Vaquita -The Search for the Desert Porpoise” is an online documentary series based on the field experiences of documentary filmmaker and photographer Chris Johnson.
Over two years (2008-2009) Chris journeyed to the northern Gulf of California, Mexico. His purpose was to search for and document the most endangered marine mammal on the planet, while giving a voice to those involved in vaquita conservation, and the locals whose livelihood depends on the fishery that is killing the desert porpoise.
With black ringed eyes and a black-lipped smile, vaquita (Phocoena sinus) is the smallest of all cetaceans (whales, dolphins and porpoises). Only an estimated 200 animals remain in a small, isolated pocket of the Sea of Cortez where their numbers continue to decline due to entanglements in gill nets set by local fishermen to catch shrimp.
With the major threat to the vaquita’s survival identified, the solution seems obvious – simply remove the entangling nets. Unfortunately, if this were done, the implications for local communities, whose livelihoods depend on the shrimp fishery, would be significant. The challenge lies in finding an amicable and cooperative solution that allows porpoises and fishermen to live together and thrive, and to find it in time.

Classroom Activity –
Objective:
Utilize information obtained from the website www.vaquita.tv’, from class discussion and from research into the extinction of the baiji (Yangtze River dolphin). Create a comparison chart/poster to address the following critical question – ‘The baiji is extinct, will vaquita follow? Students can work in pairs or small groups.
Materials:
Procedure:
(NOTE: If possible, a guest speaker from the field of ocean/cetacean research will give students further insight and access to this field of science and conservation)
Activity Answer:
Students use what they learned about the vaquita in Mexico as a catalyst for a comparative study between two species related to the issue of extinction. Students see the connectedness between species survival and human induced pressures. They will explore our responsibilities to other life on this planet, and the role of human values.
This activity gives students a real worldview of extinction, its causes, its implications and most importantly, what can be done to prevent it. It challenges students to explore their own values in regard to the natural world, and to question how human population growth is shaping life on this planet. They will also assess the relevance of science and conservation and consider its applications closer to home?
Classroom Application:
The ‘Expedition Vaquita’ activity program can be directed and adapted to a range of year levels from Grades 9-12 science, environmental education, political science, and ICT subject areas. Lateral thinking allows activities encompassing whales, dolphins and porpoises collectively called cetaceans, to link into a wide range of secondary curriculum areas. An awareness of other animals, particularly the study of charismatic keynote species, is crucial for students to learn about the issues involved in conservation and how the choices we make affect the world around us. Learning about the lives of other animals changes our ‘world view’, fosters a sense of responsibility and encourages action. The topic of cetaceans fits most obviously into the science learning area. However, there is ample opportunity to incorporate cetaceans into the geography, English and art frameworks.
