The Beaked Sea Snake, also known as the Hook-Nosed Sea Snake, is one of the most venomous sea snakes in the world. Found in coastal waters, estuaries, and river mouths, this highly aggressive species poses a significant threat to both marine life and fishermen in the Sundarbans. With its potent neurotoxic venom and secretive nature, it is one of the most deadly reptiles in the marine ecosystem.

🌍 Habitat & Distribution

The Beaked Sea Snake is found in shallow marine waters, estuaries, and river deltas across South and Southeast Asia.

🌎 Key Habitats:
✅ Sundarbans (India & Bangladesh) 🌿 – Abundant in estuarine and mangrove regions.
✅ Indian Ocean & Bay of Bengal 🌊 – Thrives in warm, shallow coastal waters.
✅ Southeast Asia & Australia – Found in coastal lagoons and river mouths.

📌 Preferred Habitat:

Mangrove forests & estuaries – Ideal for hunting small fish and crustaceans.
Shallow coastal waters – Prefers depths of 1-30 meters.
Soft, muddy seabeds – Helps ambush prey.

✨ Special Features & Adaptations

1️⃣ Extremely Venomous – Contains potent neurotoxin & myotoxin, causing paralysis, muscle breakdown, and death. ☠️
2️⃣ Aggressive Behavior – More territorial and hostile compared to other sea snakes. 😠
3️⃣ Adapted for Marine Life – Uses a paddle-like tail for fast swimming. 🌊
4️⃣ Can Hold Breath for Over 5 Hours – Special lung adaptations allow it to stay underwater for long periods. 🌬
5️⃣ Feeds on Fish & Crustaceans – Ambush predator that hunts in shallow waters. 🦐

🌿 Presence in the Sundarbans

The Sundarbans, with its brackish waters, estuaries, and tidal creeks, provides an ideal habitat for the Beaked Sea Snake.

📌 Key Areas in the Sundarbans:
✔ Mangrove-lined riverbanks – Hunting ground for fish and crustaceans.
✔ Estuarine waters near the Hooghly & Raimangal Rivers – Common sightings.
✔ Coastal shallows and muddy seabeds – Ideal for ambush hunting.

⚠️ Threats & Human Encounters

🚨 Highly Dangerous to Fishermen – Many bites occur when snakes get entangled in fishing nets.
🚨 Bycatch in Fishing Gear – Often caught accidentally, leading to injuries and fatalities.
🚨 Habitat Degradation – Pollution and climate change affect their natural habitat.
🚨 Saltwater Intrusion – Changes in water salinity can impact their prey availability.

✅ Conservation & Safety Measures

✔ Awareness Programs for Fishermen – Educating local communities about sea snake safety.
✔ Use of Protective Fishing Gear – Reducing accidental bites.
✔ Mangrove Conservation – Protecting estuaries ensures healthy snake populations.

🚨 Conservation Status

📌 IUCN Red List: Least Concern (Stable Population).
📌 CITES: Not Listed.
📌 Indian Wildlife Protection Act: Schedule IV (Moderate Protection).

Despite not being endangered, the Beaked Sea Snake’s population is affected by habitat destruction, accidental capture, and pollution.

The Beaked Sea Snake is a deadly yet fascinating predator of the Sundarbans. It plays a vital role in maintaining fish populations and the balance of marine ecosystems. However, human encounters can be fatal, making awareness and conservation efforts crucial for both humans and sea snakes to coexist safely. 🐍🌊
