Star Tortoises are terrestrial (living on land) animals found in semi-dry forests and grasslands
of our country. IIT Madras campus and adjacent Guindy National Park (GNP) have few of
these reptiles. Star tortoise gets its name from the star-like radiating yellow patterns, centered
on a bump, found on its black coloured shell (carapace). The head and front legs
of the Star Tortoise have small scales. They are
mostly active during the twilight. The rest of the day,
they lie under cover. They are most active during
the rainy season, and can be seen even during the
day. Star tortoise is omnivorous, but, mostly veg-
etarian. It feeds on succulents like Cissus
quadrangularis,('Perandai' in Tamil) which grows
in plenty in GNP and IIT, fallen fruits, grass and
similar vegetation. Sometimes they feed on snails,
and animal and bird excreta. The female lays eggs
(usually 3 to 7) in a pit dug with her hind feet. The
young tortoise start feeding voraciously within a week of birth, on the same food as the adult.
The young attain maturity in about two years. Indian Star Tortoise can live up to about 80
years. (Source: The book of Indian Reptiles and Ambhibians, J.C.Daniel, BNHS, 2002)
Deepavali or Sabdavali?
Deepavali signifies the removal of ignorance (symbolized by darkness) with knowledge (symbolized by
light). The main message of Deepavali is to celebrate this freshness as symbolized in the customs of
taking oil bath, lighting lamp and wearing new clothes. Bursting of crackers do not constitute the tradition
of celebration of Deepavali.
Bursting of crackers release a large number of harmful chemicals which pollute air, water and soil. Chemicals found
in common crackers include highly toxic heavy metals like cadmium and lead in addition to other metals like copper,
manganese, zinc, sodium, magnesium and potassium. Oxides of sulphur, phosphorous and nitrogen, which are very
corrosive and highly acidic while carbon monoxide is poisonous are formed during the burning of crackers. Sudden
burst of loud noise is harmful and terrifies animals, birds etc.not to mention sick and elderly humans and infants.
Should we be so inconsiderate to these fellow-creatures? Cracker industry employs mainly children. Should we
support a system that robs children of their childhood and keeps India illiterate? Light a lamp of hope, love and
kindness rather than noise, destruction and damage. Parents may think of buying good books for the money spent on
crackers. Remember that Deepavali is the Festival of Lamps, not the festival of crackers!
Do You Know?
Answer
Butterflies are seen on a
tree called Divi divi
(Ceasalpenia coreara),Inki
maramin Tamil which is a
native of Central America.
When you see a star tortoise: In IIT Madras campus, the Star Tortoises are seen mostly around the Stadium. When
you see them in the open areas, they are mostly going in search of grass to eat. Do not pick them up and do not put
them in wells or lake or water. They live on land and not in water. They also need some sort of protection from the hot
sun. This protection can consist of vegetation, rocks, under-growth or even planted hedges. Cutting and clearing forest
areas and under-growth will destroy home of such small animals, which escape our notice. It is illegal to keep Star tortoise
at home as pet (Schedule IV, Indian Wildlife Act). Star tortoises are declining in the wild due to illegal wildlife pet trade
in India, Singapore, Hongkong and some Gulf countries. If you see anybody involved in catching star tortoises, please
inform the Security Officer and the Wildlife Warden of Chennai (Tel: 24321471).
