Radiated Tortoise
Scientific Name: Astrochelys radiata
Category: reptile
Brief Description
A medium-sized tortoise with a highly domed shell featuring striking yellow radiating lines on a black background.
Characteristics
The carapace (top shell) is high-domed with a brilliant 'star' pattern made of yellow lines radiating from the center of each dark scute. They have thick, sturdy legs and a head that is often yellow with a dark crown.
Habitat
Found in dry thorny forests and coastal scrubland in southern and southwestern Madagascar.
When to Find It
Diurnal; most active during the day, particularly after rainfall when food is abundant.
Conservation Status
Critically Endangered (IUCN Red List)
Ecological Role
As herbivores, they play a crucial role in seed dispersal through their grazing and digestion, helping maintain the vegetation of their native ecosystem.
Easily Confused With
Indian Star Tortoise (Geochelone elegans). The Radiated Tortoise is larger and has a smoother, less 'bumpy' shell than the Indian Star Tortoise, which often has pyramidal growth on its scutes.
Observation Tips
Be respectful of their habitat; never touch or move them. In the wild, they are best spotted during the morning or evening during the wet season.
Interesting Facts
They are exceptionally long-lived; one famous specimen named Tu'i Malila, given to the Tongan royal family by Captain Cook, lived to at least 188 years old.
