Aug 8, 2016 · Male common elands develop large dewlaps that can droop more than 40 cm (15.7 inches) beneath their necks. The results indicated that, unlike in birds and lizards, the dewlap in hoofed mammals does not appear to play a role in sexual selection.

Jul 18, 2016 · In eland antelopes, large dewlap size was associated with higher, rather than lower, incidence of claw-marks (independently of age), a result which speaks against the dewlap as a predator deterrent and rather indicates a predation cost of the structure.

The common eland (Taurotragus oryx), also known as the southern eland or eland antelope, is a large-sized savannah and plains antelope found in East and Southern Africa. An adult male is around 1.6 m (5.2 ft) tall at the shoulder and can weigh up to 942 kg (2,077 lb) with a typical range of 500–600 kg (1,100–1,300 lb).

A dewlap is a longitudinal flap of skin or similar flesh that hangs beneath the lower jaw or neck of many vertebrates. More loosely, it can be various similar structures in the neck area, such as those caused by a double chin or the submandibular vocal sac of a frog .

While male and female common elands have a big saggy neck bag called a dewlap, those found in males can grow to exaggerated proportions, dangling as low as the ankles, and both sexes have spiralled horns.

Mar 12, 2025 · A dewlap, simply put, is a pendulous fold of skin hanging beneath the throat. While the exact function varies across species, the primary reasons animals develop dewlaps fall into a few key categories: sexual selection, territorial displays, …

Here I use a two-pronged approach to test hypotheses on the function of ungulate dewlaps: an interspecific comparative analysis of bovids and deer, and an intraspecific study of eland antelopes...

We recently failed to find any age-independent link between dewlap size and social status in the common eland (Tragelaphus oryx), pointing to the possibility that sexual selection may not be the primary cause of dewlap evolution in ungulates. Here I use a two-pronged approach to test hypotheses on the function of ungulate dewlaps: an ...

Both male and female common eland have seemingly excess skin that hangs from their throat, called a dewlap, though the male’s dewlap is much larger. There are various hypotheses as to the function of this dewlap.

Eland males are much larger than females, weighing 400-1000 kg compared to 300-600 kg for females. Hides are a uniform fawn color with some vertical white striping on the upper parts. A dewlap, thought to be an adaptation for heat dissapation, hangs from the throat and neck.
