Introduction
If readers are looking for an Eritrean sea monster, the most likely answer is not a hidden beast but a very real marine mammal: the dugong. Along Eritrea’s Red Sea coast, especially around the Dahlak Archipelago, people encounter an environment filled with large, unfamiliar sea animals, extensive seagrass meadows, coral reefs, turtles, dolphins and occasional whales. In such waters, reports of strange shapes at the surface do not automatically require unknown creatures. Dugongs in particular have long been linked to mermaid traditions and marine folklore across the Indian Ocean and Red Sea, making them one of the strongest natural explanations for many sea-monster stories associated with Eritrea’s coast.[eritreaembassy-japan.org]eritreaembassy-japan.org1. Biodiversity & FisheriesOnly one species of Dugong (Dugong dugon) is found in the Eritrean Red Sea. Dolphins and whales are the most c…
That does not mean every unusual sighting can be identified with certainty. The Red Sea contains enough large wildlife to generate genuine surprises. Yet the pattern is revealing: where monster stories flourish, researchers also find dugongs, sea turtles, dolphins and other marine animals capable of producing confusing glimpses in difficult viewing conditions.[eritreaembassy-japan.org]eritreaembassy-japan.org1.

Dahlak Islands and Strange Marine Sightings
The Dahlak Archipelago sits off Eritrea’s coast east of Massawa and contains some of the most important marine habitats in the country. The islands are surrounded by coral reefs, shallow bays, lagoons and extensive seagrass beds that support a rich variety of marine life.[padi.com]padi.comDiving in EritreaThe Dahlak Archipelago, made up of hundreds of islands, features untouched coral reefs, lagoons, walls, and drop-off…
For anyone interested in mystery-animal traditions, this setting matters. Sea-monster legends tend to appear where three conditions overlap:
- Large animals are present.
- Visibility is often poor because of distance, glare or waves.
- Encounters are brief and unexpected.
The Dahlak region fits that description well. Dugongs feed in shallow seagrass areas, sea turtles regularly surface for air, dolphins travel offshore, and larger cetaceans occur elsewhere in the Red Sea. A person seeing only part of an animal at dawn, dusk or from a moving boat may witness something genuinely unusual without obtaining a clear identification.[eritreaembassy-japan.org]eritreaembassy-japan.org1. Biodiversity & FisheriesOnly one species of Dugong (Dugong dugon) is found in the Eritrean Red Sea. Dolphins and whales are the most c…
Modern descriptions of Eritrea’s marine biodiversity consistently note dugongs as part of the local fauna. Government and conservation sources describe the species as occurring in shallow coastal habitats associated with seagrass and mangroves, exactly the kind of places where fishermen and travellers are most likely to encounter unexpected shapes in the water.[eritreaembassy-japan.org]eritreaembassy-japan.org1.

Dugongs as Sea Cows and Mermaid Fuel
The dugong is one of the world’s few surviving sirenians, the group of mammals often called “sea cows”. Unlike manatees, dugongs are entirely marine and spend much of their lives grazing on underwater seagrass meadows. Adults can reach several metres in length and weigh hundreds of kilograms.[UCL Blogs]blogs.ucl.ac.ukmyths in the museum the dugong and the mermaidUCL BlogsMyths in the Museum: The Dugong and the Mermaid21 Jul 2018 — Dugongs are slimmer than their cousins, but this is relative — they…
Their appearance helps explain why they became linked to legendary sea beings. From a distance, a dugong surfacing vertically, lifting a calf, or exposing only part of its body can produce a surprisingly human-like silhouette. Historians and marine biologists have frequently cited dugongs and manatees as likely contributors to mermaid stories reported by sailors.[si.edu]ocean.si.eduSmithsonian OceanFrom Mermaids to Manatees: the Myth and the Reality(The truth is that mermaids are entirely fictional.) dugong feeds on…
For Eritrea, this connection is especially relevant because dugongs are not hypothetical visitors. They are known inhabitants of the Eritrean Red Sea. Reports of a mysterious marine creature with a rounded head, smooth back or strangely human posture are therefore more plausibly linked to dugongs than to an undiscovered sea monster.[eritreaembassy-japan.org]eritreaembassy-japan.org1. Biodiversity & FisheriesOnly one species of Dugong (Dugong dugon) is found in the Eritrean Red Sea. Dolphins and whales are the most c…
A useful detail is that dugongs rarely behave like the aggressive sea serpents of popular fiction. They are generally shy herbivores. This mismatch between the animal’s real behaviour and its legendary reputation shows how folklore often transforms ordinary wildlife into something more dramatic. A fleeting encounter may become a tale, and a tale may gradually become a monster.[Smithsonian Ocean]ocean.si.eduSmithsonian OceanFrom Mermaids to Manatees: the Myth and the Reality(The truth is that mermaids are entirely fictional.) dugong feeds on…
Sea Snakes, Turtles and Mistaken Monsters
Dugongs are not the only candidates behind unusual Red Sea sightings.
Large sea turtles are common around Eritrea’s islands and coastal waters. A turtle surfacing repeatedly can create the impression of multiple humps moving through the sea, a feature commonly reported in lake-monster and sea-serpent traditions worldwide.[Eritrea Ministry Of Information]shabait.comEritrea Ministry Of InformationEritrea's Marine Biodiversity13 Apr 2019 — Similar to the land mammals, there are also marine mammals, suc…
Sea snakes provide another possibility. The Red Sea hosts several species, and long, dark bodies moving through calm water can easily resemble miniature sea serpents. Although most sea snakes are far smaller than legendary monsters, distance and poor visibility can dramatically distort perceived size. The same process has contributed to sea-serpent reports in many parts of the world.[eritreaembassy-japan.org]eritreaembassy-japan.org1. Biodiversity & FisheriesOnly one species of Dugong (Dugong dugon) is found in the Eritrean Red Sea. Dolphins and whales are the most c…
Dolphins can also create surprising illusions. When several animals surface in sequence, observers may perceive a single long creature. This effect becomes stronger in rough seas or when only parts of the animals are visible above the waterline. Eritrean waters support multiple dolphin species, making this a practical explanation for some reports of strange marine forms.[eritreaembassy-japan.org]eritreaembassy-japan.org1. Biodiversity & FisheriesOnly one species of Dugong (Dugong dugon) is found in the Eritrean Red Sea. Dolphins and whales are the most c…
Even floating debris, drifting logs and wave patterns have historically contributed to monster sightings. Human perception is good at recognising familiar shapes but not always at judging scale and distance across open water.
Why the Dugong Explanation Fits Best
When evaluating Eritrea’s marine mystery stories, the dugong stands out because it satisfies several key requirements at once.
First, it is genuinely unusual-looking. Someone unfamiliar with the species can easily regard it as something extraordinary. Second, it is present in the exact coastal habitats where unusual sightings are most likely to occur. Third, it belongs to a group of animals already associated with mermaid and sea-being traditions across many cultures.[eritreaembassy-japan.org]eritreaembassy-japan.org1. Biodiversity & FisheriesOnly one species of Dugong (Dugong dugon) is found in the Eritrean Red Sea. Dolphins and whales are the most c…
Most importantly, the dugong explanation does not require an unknown species. Eritrea’s Red Sea already contains animals capable of inspiring wonder. The Dahlak Archipelago and surrounding coast are among the richest marine environments in the region, and the presence of dugongs, turtles, dolphins and other large marine animals means that strange sightings can emerge naturally from encounters with real wildlife.[padi.com]padi.comDiving in EritreaThe Dahlak Archipelago, made up of hundreds of islands, features untouched coral reefs, lagoons, walls, and drop-off…
For that reason, Eritrea’s sea-monster tradition is often most interesting not as evidence for hidden creatures, but as an example of how genuine marine biology and folklore meet. The Red Sea does not need mythical beasts to seem mysterious; its living inhabitants are unusual enough already.[eritreaembassy-japan.org]eritreaembassy-japan.org1.
