The Indian giant squirrel, or Malabar giant squirrel, (Ratufa indica) is a large tree squirrel species genus Ratufa native to India. It is a large-bodied diurnal, arboreal, and herbivorous squirrel found in South Asia. It is called ‘Shekru’ in Marathi and is state animal of Maharashtra.
The Indian giant squirrel is an upper-canopy dwelling species, which rarely leaves the trees, and requires “tall profusely branched trees for the construction of nests”.It travels from tree to tree with jumps of up to 6 m (20 ft). When in danger, the Ratufa indica often freezes or flattens itself against the tree trunk, instead of fleeing. Its main predators are the birds of prey and the leopard.The Giant Squirrel is mostly active in the early hours of the morning and in the evening, resting in the midday. It is a shy, wary animal and not easy to discover.

They are typically solitary animals that only come together for breeding. The species is believed to play a substantial role in shaping the ecosystem of its habitat by engaging in seed dispersal.
