100 years ago: A huge python on board a steamer

1. At a Glance

• An archival news item, reprinted in The Hindu's "100 years ago" column. It reports that a python was found coiled among cargo in the hold of the steamer "Creeve Hall" at Calcutta in October 1926 [1].
• The ship had arrived from Colombo (Ceylon, now Sri Lanka). This makes it an early recorded case of a live animal travelling as a stowaway in maritime cargo [1].
• UPSC relevance: it links colonial port history (Calcutta) with today's issues of invasive alien species (IAS), biosecurity at ports and wildlife trade. Ports are a recognised entry pathway for stowaway organisms [3].
• It also gives a glimpse of colonial-era administration (a Reserve Force, a River Traffic Police), port labour (the "coolies") and the Anglo-Indian press (the "Englishman") [1].

2. Why in the News

• The item was reprinted in The Hindu's archival column (International page, Page 9) on its centenary [1].
• There is no policy trigger. It is a static/historical topic that is useful as a hook for invasive species and port biosecurity. Burmese pythons remain a well-known invasive-species case in the USA [3][4].

3. Background & Evolution

• 1926 (Oct 4, Monday forenoon): an alarm was raised on the "Creeve Hall", lying at No. 6 jetty, Calcutta, the day after it arrived from Colombo [1].
• Discovery: coolies unloading the twin decks of No. 6 hatch found the python coiled in a corner beside the cargo [1].
• Response: the chief officer told the police. Inspector Humble (Reserve Force) and Sergeant Green (River Traffic Police) came on board, both armed with shot guns. Police, ship's officers with electric torches and coolies shifting cargo then hunted for the snake [1].
• Reporting: the account came via the Calcutta paper the "Englishman". There was no issue of The Hindu dated Oct 6, 1926, so the column used the Oct 5, 1926 issue [1].
• Modern parallel: in the early 1980s, a few escaped or released pet pythons at the southern end of Everglades National Park founded a wild Burmese python population in Florida [3]. Hurricane Andrew (1992) allowed more snakes to escape [3].

5. Multi-Dimensional Analysis

Historical

• Calcutta was a major colonial port with regular steamer links to Colombo, part of the Indian Ocean trade circuit [1].
• The response involved specialised colonial policing (a River Traffic Police) and a manual labour force (the "coolies"), which shows how the port was organised [1].

Environmental

• Ships and cargo are pathways for stowaway organisms. Closer inspection of international shipments is recommended to catch them [3].
• Once established, large constrictors cause severe declines in mammals, as in the Everglades (≥87% for several species) [3].

Administrative / Governance

• In 1926, the response was ad hoc: police with shotguns. Today, the job of preventing such entries falls to quarantine and biosecurity agencies at ports [1][3].
• The Florida case shows that pet-trade escapes and releases, not only stowaways, drive invasions [3].

Economic

• Large-scale exotic pet trade (>300,000 pythons imported into the U.S.) creates spillover risks to ecology and the economy [3].

Ethical

• In 1926, the only response was armed extermination. Today the approach weighs animal welfare against humane capture, rescue and repatriation (an interpretive point, not from the sources).

6. Recent Developments (last 12–18 months)

• Oct 2026: The Hindu reprinted the 1926 report in its "100 years ago" column [1].
• The retrieved sources contain no specific dated 2025–26 policy development tied to this topic. Static topic: no recent trigger.

7. Prelims Hooks

• The python was found aboard the steamer "Creeve Hall" at Calcutta, Oct 1926 [1].
• The ship had arrived from Colombo the previous day [1].
• It was berthed at No. 6 jetty, and the snake was in the twin decks of No. 6 hatch [1].
• The 1926 report was originally carried by the Calcutta daily the "Englishman" [1].
• River Traffic Police and the Reserve Force responded, armed with shotguns [1].
• The Burmese python is Python bivittatus [2][5].
• The U.S. imported >300,000 Burmese pythons in about 30 years for the exotic pet trade [3].
• The Florida wild population started in the early 1980s at the southern end of Everglades National Park [3].
• Hurricane Andrew (1992) let captive pythons escape [3].
• Pythons have reduced Everglades deer, bobcat, raccoon and opossum numbers by ≥87% [3].
• Pythons have effectively eliminated foxes and rabbits in parts of the Everglades [3].
• Pythons have invaded Big Cypress National Preserve in addition to Everglades NP [3].

8. Why the Ship Was the Smaller Risk: Today the Danger Comes by Trade

• A stowaway is one accident. The pet trade brings animals in again and again, on purpose
• In 1926, one python came in hidden in cargo, by chance [1].
• Florida's pythons did not come that way. More than 300,000 Burmese pythons were brought into the U.S. as pets, and escaped or released pets started the wild population [3].

• So the bigger threat is the steady, legal or illegal flow of animals people want to keep, not the odd snake in a ship's hold.

• In India, this flow now comes mostly through airports, not the docks

• In 2022 alone, WWF-India recorded 56 seizures involving about 4,000 exotic animals [7].
• Most of the trafficking goes through the Chennai, Bengaluru (Kempegowda) and Mumbai airports, with Kochi, Visakhapatnam and Sri Vijaya Puram (Port Blair) also used [7].

• Royal ball pythons are among the animals traded [7]. The 1926 story's 'python on board' has become a python in a passenger's bag.

• Why this matters for the exam: a GS-III answer that talks only about 'port biosecurity' misses the main pathway. Name both. A pathway is the route by which a species reaches a new place: cargo stowaways are one, the pet trade is another.

9. Why India Still Does Not Know How Many Exotic Pets It Has

• The 2020 count depended on owners choosing to come forward
• The 2020 Voluntary Disclosure Scheme let owners declare their exotic pets, meaning animals that are not native to India [7].
• Over 40,000 people across 30 states and UTs declared exotic pets [7].

• The scheme was voluntary, so anyone who did not want the government to know simply stayed silent. The report itself says this is likely only a fraction of real ownership [7].

• The market is growing faster than the rules

• India's exotic pet market was about US$42.6 million in 2024. It is projected to reach US$75.8 million by 2030 [7].
• That is a CAGR (average yearly growth rate) of 10.2% [7].

• Experts say the Wildlife (Protection) Act, 1972 and the Biological Diversity Act, 2002 give a strong base, but are not equipped for the size and changing nature of this trade [7].

• What this means: if a pet python escapes in India, nobody may know who owned it or how many more exist. That is exactly the blind spot that let Florida's problem grow unnoticed for years [3].

10. Why Plans on Paper Do Not Stop Invaders

• Most countries have written a target. Very few have a law behind it
• The IPBES (an intergovernmental science panel on nature, like the IPCC for climate) assessed invasive alien species in 2023 [6].
• 80% of countries have invasive-species targets in their national biodiversity plans [6].
• Only 17% have specific national laws on them, and 45% do not invest in managing them at all [6].

• A target without a law cannot stop a shipment, fine a trader or fund a response team.

• The cost of doing nothing keeps rising

• Invasive alien species cost the world more than US$423 billion in 2019 [6].
• They were a major factor in 60% of recorded plant and animal extinctions, and the only cause in 16% [6].

• About 200 new invasive species are reported every year [6].

• Once an invader settles in, it is too late to undo the damage cheaply

• In the Everglades, deer, bobcats, raccoons and opossums fell by 87% or more after pythons spread [3].
• Pythons have also spread to Big Cypress National Preserve and other protected lands [3]. This shows how hard it is to stop them after they are established.

11. How to Stop the Next Python Before It Leaves the Hold

• MoEFCC should turn the one-time 2020 disclosure into a regular, compulsory register
• The 2020 scheme was voluntary and gave only a partial picture [7].

• A compulsory register of exotic pets, with renewals, would show who keeps what and where. Then an escaped animal could be traced back to its owner.

• Customs should focus checks on the known trafficking airports

• Seizures are concentrated at Chennai, Bengaluru and Mumbai airports [7].

• Putting reptile-trained staff and scanners at these few points covers most of the known flow [7].

• Port and airport authorities should follow the IPBES formula: prevent, detect early, respond fast

• IPBES says preparedness, early detection and rapid response can prevent future invasions [6].
• USGS recommends closer inspection of international shipments to catch stowaways [3].

• In practice: a trained team and a fixed plan at each port. Compare this with 1926, when the response was policemen with shotguns making it up on the spot [1].

• Learn from Florida's timeline

• Florida's wild population began with a few pets in the early 1980s [3].
• Hurricane Andrew in 1992 then let more captive snakes escape [3].
• Lesson for India: disaster plans for zoos, breeders and pet shops in cyclone-prone coastal states must include stopping animals from escaping.

12. Reading a 100-Year-Old Clipping Like a Historian

• Notice who is named and who is not
• The British officers are named: Inspector Humble and Sergeant Green [1].
• The 'coolies' (port workers) who found the snake and moved the cargo during the hunt are not named at all [1].

• They faced the real danger, but the record leaves them out. This is a common pattern in colonial records, and a useful point for GS-I answers on colonial labour.

• Notice whose eyes we are seeing through

• The report came from the Englishman, a paper of Calcutta's British community [1]. It tells the story from the officers' side.

• Notice what is missing

• The species of the python is not given [1]. Nobody records where it came from, or whether it was caught or killed.
• In 1926, a snake in cargo was a security scare, not a biological risk. That shift in thinking is itself the story's link to today.

13. Anchors for Answers

• Data: Invasive alien species cost the world over US$423 billion in 2019. They were a major factor in 60% of global extinctions [6]
• Data: Only 17% of countries have specific laws on invasive species, though 80% have targets in their plans [6]
• Data: Over 40,000 people in 30 states and UTs declared exotic pets under the 2020 disclosure scheme. WWF-India recorded 56 seizures of about 4,000 exotic animals in 2022 [7]
• Report/Committee: IPBES Thematic Assessment Report on Invasive Alien Species, 2023 [6]
• Law/Case: Wildlife (Protection) Act, 1972 and Biological Diversity Act, 2002. Both are seen as not equipped for the exotic pet trade [7]
• Comparison: USA (Florida). More than 300,000 pythons were imported as pets, and escaped or released pets started a wild population. Everglades mammals fell by 87% or more [3]
• Scheme: Voluntary Disclosure Scheme for exotic live species (2020), India's first attempt to count exotic pets. It was voluntary, so the count is incomplete [7]

14. Mains Relevance

• GS-I: Modern Indian History (colonial economy, ports, urban Calcutta). GS-III: Environment, biodiversity conservation, invasive species; security challenges at ports and borders.
• Possible question stems: 1. Invasive alien species are a silent threat to biodiversity. Examine the role of trade pathways and suggest a biosecurity framework for Indian ports. 2. Using the case of Burmese pythons in the Everglades, discuss how the exotic pet trade can trigger ecological disasters. What lessons does it hold for India? 3. Colonial port cities were nodes of both commerce and ecological exchange. Discuss with reference to Calcutta.

16. NCERT Concepts to Revise

• Invasive alien species (Geography): The note's main hook: stowaway and pet-trade animals can become invasive species that harm native wildlife, as in Florida.
• Exotic species (Geography): A python carried abroad is an exotic species, one introduced outside its natural range, deliberately or by accident.
• CITES (Geography): This treaty regulates international trade in wild animals such as pythons, which is the exotic pet trade angle.
• Wildlife (Protection) Act 1972 (Geography): India's main wildlife law, amended in 2022 to cover exotic live species and implement CITES.
• Syama Prasad Mookerjee Port (Geography): This is today's Kolkata port, the colonial Calcutta port where the steamer docked.
• Port of call (Geography): Colombo was the ship's last stop before Calcutta, so this explains how sea routes link ports.

17. Common Errors / Trap Areas

• Indian python vs Burmese python: P. molurus (Indian) and P. bivittatus (Burmese) are now treated as separate species. The Burmese python was formerly a subspecies, P. molurus bivittatus [2][5].
• Cause of the Florida invasion: the main driver was pet-trade releases and escapes, not shipping stowaways. Hurricane Andrew (1992) added escapes [3].
• The source of the 1926 item: the "Englishman" was the original reporter, not The Hindu. The Hindu reprinted the Oct 5, 1926 item because there was no Oct 6 issue [1].
• Wrong police unit: it was the River Traffic Police, not the Port Police or Customs [1].
