Biodiversity, plants & animals Medium

Regarding Peacock tarantula (Gooty tarantula), consider the following statements:

  1. I.It is an omnivorous crustacean.
  2. II.Its natural habitat in India is only limited to some forest areas.
  3. III.In its natural habitat, it is an arboreal species.

Which of the statements given above is/are correct?

Answer & explanation

Answer: (d) II and III

The Gooty (peacock) tarantula, Poecilotheria metallica, is a spider, so it is an arachnid and not a crustacean, and it hunts animal prey rather than being an omnivore. It is a tree-dwelling species restricted to a few forest patches in the Eastern Ghats, so II and III are correct.

  • ✗ I Tarantulas belong to the class Arachnida (order Araneae, family Theraphosidae), not to the crustaceans, and Britannica says they feed mainly at night on insects and occasionally on small frogs, toads and mice, so 'omnivorous crustacean' is wrong on both counts.
  • ✓ II The species is endemic to India and is Critically Endangered because it is restricted to a small, highly degraded forest area in the Eastern Ghats (between Nandyal and Giddalur, Andhra Pradesh); a later record extended its range to the Eastern Ghats of Tamil Nadu, but it remains confined to a few forest areas.
  • ✓ III Its genus, Poecilotheria, is the only tarantula genus that is specifically arboreal, living in trees in the forests of peninsular India and Sri Lanka.

Remember · Gooty (peacock) tarantula, Poecilotheria metallica: an arboreal spider (arachnid), endemic to a small Eastern Ghats forest area in India; IUCN Critically Endangered.
