Dugong size: How big do they get?

How big does a Dugong get? Here is an overview over the average adult age:

A grown Dugong (Dugong dugon) reaches an average size of 2.55 meter (8′ 5″).

When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 70 years, they grow from 23.48 kg (51.76 lbs) to 295 kg (650.36 lbs). A Dugong has 1 babies at once. The Dugong (genus: Dugong) is a member of the family Dugongidae.

As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.

The average adult size of a Dugong is (8' 5

The dugong (; Dugong dugon) is a medium-sized marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller’s sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century. The dugong is the only strictly herbivorous marine mammal.The dugong is the only sirenian in its range, which spans the waters of some 40 countries and territories throughout the Indo-West Pacific. The dugong is largely dependent on seagrass communities for subsistence and is thus restricted to the coastal habitats which support seagrass meadows, with the largest dugong concentrations typically occurring in wide, shallow, protected areas such as bays, mangrove channels, the waters of large inshore islands and inter-reefal waters. The northern waters of Australia between Shark Bay and Moreton Bay are believed to be the dugong’s contemporary stronghold.Like all modern sirenians, the dugong has a fusiform body with no dorsal fin or hind limbs. The forelimbs or flippers are paddle-like. The dugong is easily distinguished from the manatees by its fluked, dolphin-like tail, but also possesses a unique skull and teeth. Its snout is sharply downturned, an adaptation for feeding in benthic seagrass communities. The molar teeth are simple and peg-like unlike the more elaborate molar dentition of manatees.The dugong has been hunted for thousands of years for its meat and oil. Traditional hunting still has great cultural significance in several countries in its modern range, particularly northern Australia and the Pacific Islands. The dugong’s current distribution is fragmented, and many populations are believed to be close to extinction. The IUCN lists the dugong as a species vulnerable to extinction, while the Convention on International Trade in Endangered Species limits or bans the trade of derived products. Despite being legally protected in many countries, the main causes of population decline remain anthropogenic and include fishing-related fatalities, habitat degradation and hunting. With its long lifespan of 70 years or more, and slow rate of reproduction, the dugong is especially vulnerable to extinction.
