उत्तर
Classification of threatened species of animals:
- Endangered species: These are the species whose either number is declined or habitat is shrunk to such an extent that they can be extinct in the near future if conservative measures are not implemented. e.g. Lion-tailed monkey (Lion-tailed macaque), Lesser florican.
- Rare species: Number of these organisms is considerably declined. Members of this species being endemic may become extinct very fast. These species are rarely encountered and very uncommon. e.g. Red Panda, Musk deer.
- Vulnerable species: Number of these organisms is extremely less and continues to decline. Continuous decline in their number is distressful. These species can quickly move to rare or endangered species groups if appropriate conservation measures are not implemented. e.g. Lion, Tiger.
- Indeterminate species: These organisms appear to be endangered but there is not enough information about these organisms due to their behavioral habits (like shyness). e.g. Giant squirrel (Shekru).
