Overview
The dugong is a large marine mammal closely related to manatees and is the only fully marine herbivorous mammal in the world. In the waters around Tawau, dugongs depend almost entirely on healthy seagrass meadows.
Identification
- Streamlined, grayish body with a whale-like tail
- Downturned snout adapted for grazing seagrass
- Slow-moving and usually seen alone or in pairs
Seagrass Habitat
Dugongs are highly specialized feeders. They inhabit shallow coastal waters where seagrass grows, usually at depths of less than 10 meters.
Seagrass meadows also act as nurseries for fish, stabilize sediments, and store carbon, making them among the most valuable coastal ecosystems.
Diet & Feeding Behavior
Dugongs feed almost exclusively on seagrass. As they graze, they create distinctive feeding trails on the seabed.
This grazing helps maintain healthy seagrass beds by encouraging new growth and preventing overcrowding.
Dugongs in the Tawau Region
Dugongs are rarely seen and naturally elusive. In the Tawau region, they are occasionally reported in:
- Quiet coastal bays
- Shallow nearshore waters with extensive seagrass
- Areas with minimal boat traffic
Their presence indicates relatively intact coastal ecosystems.
Threats & Challenges
- Loss of seagrass due to coastal development
- Boat strikes in shallow waters
- Fishing gear entanglement
- Water pollution and sedimentation
Conservation & Protection
Dugongs are protected under Malaysian wildlife law and are classified as Vulnerable globally. Conservation priorities include protecting seagrass meadows, reducing boat disturbance, and raising public awareness.
Did You Know?
- Dugongs can live for over 70 years.
- They may consume up to 40 kg of seagrass per day.
- The name “dugong” comes from a Malay word meaning “lady of the sea”.
