  • Both hatched during 1997 and were private donations to the Zoo
  • Are very hard to tell apart — keepers use subtle differences in shell patterns to identify them
  • Arrived at the Santa Barbara Zoo in May 1998

From the Keepers

These tortoises are like puppy dogs! They follow us, walk in circles around us, and brush up against us, and seem to enjoy shell scratches. Sure, they move slowly, but they are very engaging. They also are attracted to bright colors, like shoes, and walk towards them.

Will Work for Food

At the Zoo, the radiated tortoises eat dandelion greens, cilantro, kale, collard greens, grass hay, herbaceous plants, and specially formulated low-starch/high-fiber tortoise pellets. Keepers position the food around their enclosure so the tortoises have to “work” to get it, encouraging them to be active. Enrichment includes cactus paddles, which the species eat in the wild. Fun fact: the paddles are often sourced from the Zoo’s own prickly pear plants.

Madagascar Native is Critically Endangered

Radiated tortoises have disappeared from more than half of their historic range, the spiny forest ecoregion in southern Madagascar. They are now critically endangered due to hunting for food and capture for the black market international pet trade.

In 2011, Utah’s Hogle Zoo and the Turtle Survival Alliance (TSA) started a public awareness campaign about tortoise conservation in Madagascar, including an eight-minute long video about the crisis.

In January 2018, the Association of Zoo’s and Aquarium (AZA) added radiated tortoises to their SAFE: Saving Animals from Extinction initiative, bringing the number of SAFE species to 14.

SAFE combines the power of zoo and aquarium visitors with the resources and collective expertise of AZA-accredited zoos and aquariums and partners to save the most vulnerable wildlife species from extinction and protect them for future generations.

Black Market Crisis

In Madagascar, huge numbers of radiated tortoises destined for the black market in Asia have been recently confiscated and rescued.

In April 2018, 10,000 tortoises were found in just one house in Tulear, Madagascar. Another 7,350 were seized elsewhere in October 2018.

Nearly 70 conservation-related organizations globally, including 38 AZA zoos and aquariums, have rally to help the confiscated tortoises by sending medical supplies and personnel, and contributing funds.

Why are the numbers so high? The majority of the smuggling of these animals out of Madagascar is due to the black market pet trade. But in Asia, radiated tortoises are also considered a delicacy and are believed to have aphrodisiac powers. A live radiated tortoise can fetch the equivalent of $1,000 to $2,000.

Madagascar supports nearly 5% of the plant and animal species on Earth, but is only around the size of Texas. The island is also home to hundreds of species found nowhere else on the planet, such as radiated tortoises, lemurs, and fossa.

Conservation Status

Radiated tortoises are critically endangered on the IUCN Red List. Should current declines continue, the species could be extinct in the wild within the next 45 years.
