The ploughshare tortoise, also known as the Angonoka tortoise, is one of the rarest tortoise species in the world, with only a few hundred individuals left in the wild, and it shares its habitat with other endangered species such as the radiated tortoise.
Background on Ploughshare Tortoises
The Ploughshare tortoise (Astrochelys yniphora) is a critically endangered species of tortoise native to Madagascar. They are also known as Angonoka tortoises and have been listed as one of the world’s 25 most endangered turtles and tortoises by the Turtle Conservation Coalition.
This is why keeping Ploughshare tortoise as a pet is a very controversial topic and I highly recommend you consider the ethical and legal aspects before getting one as a pet.
Natural Habitat and Distribution
Ploughshare tortoises are found in a small area of northwest Madagascar, near the town of Baly Bay. They inhabit a range of different habitats, including dry deciduous forests, spiny thickets, and rocky outcrops. These tortoises are also found in the Baly Bay National Park, which is the only protected area for this species and is considered their last stronghold.
While the ploughshare tortoise is critically endangered, the western painted turtle is a common sight in many North American waterways.
Biology and Anatomy
Ploughshare tortoises are medium-sized tortoises, reaching an average length of 30-40 cm (12-16 inches) and weighing between 6-8 kg (13-17 pounds). They have a distinctive golden-yellow color on the carapace (upper shell) and the plastron (under shell). They also have a unique pattern of raised, serrated scales on their carapace, which gives them their common name. Their head, legs, and tail are a dark brown color and have a slightly pointed tail.
Ploughshare tortoises can live for over 100 years in captivity with proper care. It is important to note that this species is long-lived and should be considered a lifelong commitment.
Behavior and Temperament
Ploughshare tortoises are generally calm and docile, but they can be shy around new people and surroundings. They are also very active and enjoy exploring their enclosure, so it’s important to provide them with plenty of space. They are also known to be very social animals and can be kept with other tortoises of the same species.
The ploughshare tortoise is a critically endangered species that requires specialized care, much like the red eared slider.
Housing and Enclosure
Ploughshare tortoises require a large, well-constructed enclosure that mimics their natural habitat as much as possible. A minimum enclosure size of 8×4 feet is recommended for one adult, but larger is always better. The enclosure should be equipped with a basking spot that provides a heat source and UVB lighting, a hiding spot, and a large area for them to explore and move around. It is also important to provide them with a shallow water dish for drinking and soaking. The enclosure should be kept clean and the bedding should be changed regularly.
Lighting and Temperature
Ploughshare tortoises require a basking spot that provides a heat source and UVB lighting. The basking spot should be kept at a temperature of 85-90 degrees Fahrenheit, and the rest of the enclosure should be kept at a temperature of 75-80 degrees Fahrenheit. UVB lighting is essential for the proper absorption of calcium, which is necessary for the growth and health of the tortoise’s shell. A UVB bulb should be replaced every 6 months.
Diet and Nutrition
Ploughshare tortoises are herbivores and their diet should consist mostly of leafy greens, such as collard greens, turnip greens, and dandelion greens. They also enjoy a variety of fruits, such as papaya, berries, and melon. It is important to provide a calcium supplement, such as a cuttlebone or a calcium powder, to ensure proper shell growth. A balanced diet and proper nutrition are essential for the overall health and well-being of the tortoise.
Health and Medical Care
It is important to regularly check your tortoise for any signs of illness or injury. Signs of illness include lethargy, loss of appetite, and abnormal feces. It’s also important to take them to a veterinarian experienced with reptiles, at least once a year for a check-up. It is important to note that Ploughshare tortoises are critically endangered species and it is illegal to capture or trade wild individuals, thus you should obtain them from reputable breeders or rescue centers.
Breeding and Reproduction
Ploughshare tortoises reach sexual maturity at around 15-20 years of age. They have a distinct breeding season, which usually occurs between November and January. During this time, males will engage in aggressive courtship behaviors, such as head-bobbing and biting, to attract females.
Incubation and Hatchling Care
After mating, the female will lay a clutch of 2-8 eggs in a nest that she digs in the ground. The eggs will incubate for an average of 120 days. It is important to maintain a high humidity level and a consistent temperature during incubation. Hatchlings should be kept in a separate enclosure and provided with a heat source and UVB lighting. They should also be fed a diet of leafy greens and a calcium supplement.
Challenges and Considerations
Breeding Ploughshare tortoises can be challenging and requires a lot of knowledge and experience. It is also important to consider the ethical and legal implications of breeding this critically endangered species.
Additionally, it is important to consider the possibility of not being able to find homes for all of the hatchlings and to have a plan in place for their care and management. It is also crucial to only breed from captive-bred individuals, not wild-caught ones, in order to not contribute to the decline of a wild population.
My Private Notes
As someone who has had experience with Ploughshare tortoises, I can attest to the fact that they are truly fascinating creatures. They are not only beautiful, but they also have a unique and fascinating biology and history. Here are some non-obvious tips that I’ve learned through my experience:
- Ploughshare tortoises are very active and enjoy exploring their enclosure, so it’s important to provide them with plenty of space. I recommend adding hiding spots, climbing structures, and other enrichment items to keep them mentally stimulated.
- It’s important to be consistent with their diet and feeding schedule. I’ve found that my Ploughshare tortoises tend to be more active and explore more when they are well-fed.
- Be prepared for the long-term commitment. As I’ve mentioned before, these tortoises can live for over 100 years, so it’s important to be prepared for the long-term care and responsibility that comes with owning one.
- Keep an eye on their hydration levels. I’ve found that my Ploughshare tortoises are more prone to dehydration than other species I’ve kept, so it’s important to make sure they have access to fresh water and to mist them regularly.
- Finally, it’s important to stay informed and educated about the conservation status of this species. Supporting conservation efforts and being a responsible pet owner is crucial for the survival of the Ploughshare tortoises in the wild.
