Dugongs or “Sea Cows”: Protecting Gentle Giants of the Ocean

Introduction

Let’s look at the peaceful world of dugongs, the ocean’s gentle giants. These serene creatures thrive in places where warm turquoise waters meet sandy shores and play a key role in maintaining the balance of the coastal ecosystem.

Who Are the Dugongs?

Dugongs, also called Sea Cows, are the ocean’s calmest residents, closely related to manatees. With their sleek bodies and distinctive snouts, they’re perfectly built for life beneath the waves. Due to their looks, they are believed to be the original inspiration for tales of mermaids and sirens.

Their diet is all about seagrass, making them unique as the only marine mammals to stick to a strictly plant-based menu.

Why are They Called Sea Cows?

They are often called Sea Cows due to their gentle nature, size (they can weigh up to 800 pounds) and diet.

These gentle giants spend their days gliding through the water, grazing on seagrass meadows, which are crucial for both their survival and the health of the marine ecosystem.

Are They Endangered? 

They are classified by the IUCN (International Union for Conservation of Nature )as vulnerable to extinction. The main reason is the loss of seagrass habitats, which is their main source of food. This is why the conservation of seagrass habitats is so important.

Where do Dugongs Live?

Meadows are the perfect place for dugongs to relax and feed. They prefer shallow coastal waters and estuaries, enjoying the calm and abundant seagrass.

Dugongs live in lush seagrass beds stretching across the Indian or Pacific Ocean floor. They can be found in around 40 countries on the coastlines of Indian and Pacific Oceans. The most significant number lives in Australia, but they can often be found in Indonesia, even in East Africa. 

Dugongs are also known to move with the seasons, following the best feeding spots. This migration helps ensure the meadows remain healthy and supports the wider marine community that relies on these habitats.

Are Dugongs related to Manatee?

They are related to both manatees and elephants. They share many physical characteristics with manatees, including a streamlined body with a rounded, blubbery shape, a broad tail fluke, and paddle-like flippers. 

Fun Facts About Dugongs

• Dugongs have been observed using marine sponges to protect their sensitive snouts while grazing on seagrass.
• They can hold their breath for up to six minutes, surfacing every few minutes for air.
• Dugongs communicate with each other using chirps, whistles, and bell-like sounds.
• Female dugongs carry their calves for about 13 months and care for them for around 18 months, forming strong bonds with their young.
• Despite their size, dugongs are agile swimmers, reaching speeds of up to 20 kilometres per hour (12 miles per hour).
• Some dugongs travel great distances – up to 1,000 kilometres (620 miles) – in search of food and peaceful habitats.
• These ocean dwellers can live for over 70 years in the wild, making them long-term residents of the seas.

Why Dugongs Matter in Marine Ecosystems

Dugongs aren’t just passive grazers – they’re crucial to the health of the ocean’s ecosystems. As they graze on seagrass, they help maintain the meadows by keeping them from overgrowing. This grazing allows the ecosystem to flourish, creating a home for all kinds of marine life. Dugongs act as natural landscapers, shaping the ocean’s underwater environment.

Seagrass meadows, where dugongs feed, are also key to storing carbon, helping to fight climate change. So, by protecting dugongs, we’re also contributing to a larger environmental cause, ensuring the ocean remains a healthy and thriving space.

Marine Conservation: Join Efforts to Restore Seagrass and Protect Dugongs

If you’re ready to take action and help protect these incredible creatures, there are many ways to do it. You can join seagrass restoration projects.

As a student, you can find internships on ecosystem restoration, such an internship project in Thailand. Project is focused on ecosystem restoration, and some of the tasks include mangrove and seagrass restoration. 

By joining the project, you’ll play a role in protecting this unique marine habitat and helping to ensure the future of dugongs in the region.

Why It Matters to Restore Seagrass and Protect Dugongs

Dugongs are more than just gentle giants; they’re key players in maintaining the health of their ecosystems. By protecting their habitats and supporting conservation efforts, we’re ensuring that these peaceful creatures continue to thrive, alongside the many species that depend on the seagrass meadows they shape. The future of our oceans relies on the care we give today – and dugongs are a vital part of that future.
