what's the rarest Creature you've encountered? doesn't have to be a frog but any kind of amphibian or perhaps even a non-amphibian

I saw two Astrochelys yniphora specimens in the wild in 2006, while I was in Madagascar on my first trip with my father and a group of other herp enthusiasts. At the time, there were an estimated 800 specimens in the wild. By 2008, the population had dropped to ca 400 individuals, and as of 2018 the species has been considered functionally extinct in the wild, according to Pedrono & Clausen (2018) and the Durrell Wildlife Conservation Trust.

I think this is very probably the rarest creature I have seen in the wild. I guess I have seen some animals in zoos that are also extinct in the wild, or close to it, but I think that doesn't really count. I have also collected the only known specimens of quite a number of frog and reptile species, but those species are probably mostly fine in terms of population numbers, just no-one has checked. And I have seen and handled quite a large number of specimens of extinct species at museums, but that's a very different thing, of course.

The Radiant Radiated Tortoise

One of the rarest tortoise species in the world, the radiated tortoise (Astrochelys radiata) is only native to the island of Madagascar. They can be found throughout the island, but they are most abundant in the southern part of the island, among the scrub and thorny brush. In addition to their home range, this species has also been introduced to the nearby island of Reunion.

Like all tortoises, the radiated tortoise is an herbivore. Grasses, leaves, and decaying vegetation constitute about 80-90% of their diet, and is supplemented with flowers, fruits, and cacti- particularly prickly pear cacti. Finding food also makes up the majority of their daily activity, as they move around their territories to find fresh growth. A. radiata’s thick shell deters most predators, but reptiles and birds are known to feed on eggs and hatchlings.

The radiated tortoise mates all year round, due to the relatively consistent climate and food supply. When a male encounters a suitable female, he seduces her by bobbing his head and smelling her hind legs. If she’s receptive, he will mount her in a surprisingly noisy, violent affair-- both parties hiss and grunt, and in some cases the female’s shell may crack from the force of the male’s plastron striking it. 

If mating is successful, the female lays a clutch of 3-12 eggs in an excavated burrow. These eggs incubate anywhere from 5 to 8 months, depending on the average temperature of the nest. The young that emerge are quite small, only 3-4 cm (1-1.5 in) long and lacking the distinctive patterned dome shell. These tortoises will take 16-20 years to reach their full size and become ready to mate. The lifespan of this species varies widely; most individuals live only 40-60 years, but some have been recorded reaching 188.

A. radiata has a very distinctive look. The shells are extremely curved, and is dark brown or black with a striking yellow star pattern that gives the species its name. The rest of the body is dusty yellow, except for a dark patch on the back of the head. The limbs and tail are also covered in thick, raised scales that offer extra protection against predators and help the tortoise retain moisture. Compared to other tortoise species in terms of size, the radiated tortoise is right in the middle: at their maximum, they can reach 40 cm (16 in) long and weigh up to 15 kg (35 lbs).

Conservation status: The IUCN has classified the radiated tortoise as Critically Endangered, due to habitat loss and overcollection for the pet trade. Wild populations have been Many zoos and conservation programs keep captive populations for breeding and reintroduction.

The spider tortoise (Pyxis arachnoides) is a species of tortoise in the family Testudinidae that is endemic to Madagascar and is one of only two species in the genus Pyxis.

The remaining tortoises are found only in south western Madagascar, where they inhabit the spiny vegetation of the sandy coastal areas.

Very little is known about the life cycle of this endangered tortoise, which is believed to live for up to 70 years. Here they feed on young leaves, insect larvae, and even the droppings of larger animals. When the wet season arrives, the dormancy period ends and the tortoises begin to mate. Females only lay one egg when they reproduce, and the egg is incubated for about 220–250 days.

Their trade is illegal in Madagascar, but they are extensively smuggled for food, body parts, and illegal pets.
