Animals Living in Sand Dunes

Animals living in sand dunes always fascinated me. The extreme conditions like heat or dryness pose quite a challenge for animals living in the desert. But, sandy terrain that requires a great effort while taking each step is another problem; particularly to all animals that the sand dunes are their habitat. And Indeed many animals living in sandy terrain have special ways to overcome this.

Animals Living in Sand Dunes: The Egyptian Predator Beetle

Firstly, the Egyptian predator beetle, very common to be found in the Negev sand dunes. These beetles have an unusual life cycle; young larvae enter ants’ nests and remain there feeding on the ants and their larvae. They soon assume the scent of their ant hosts and are accepted as members of the colony.

They move about with their bodies lifted high up off the ground to avoid the heat of the substrate. Their mandibles, although large, are not strong enough for defense. Instead, they squirt an acrid fluid from the anus to disable their enemies. This defense strategy has earned them the popular name of ‘oogpister’ i.e. ‘eye-squirter’ (in French). Their large eyes, mandibles, and speed of movement are similar to those of tiger beetles, but these beetles are flightless.

Animals Living in Sand Dunes: Egyptian Sand Gecko

Unlike other geckos, dune geckos can not climb up smooth surfaces. Instead, they prefer to dig. During the day, they usually hide in burrows or in caves, though often they are out and about during the day. They sometimes appear slow, but they can be extremely fast. Camouflage in the sand helps them remain inconspicuous, especially when hunting. They eat mainly crickets and mealworms. In order to move easily in the sand their fingers are relatively big. An even better example for a lizard with a bigger foot would be Nidua fringe-fingered lizard. 

The Negev: The Little Sahara Desert

If one desires to really get to know the fauna in the sand dunes he should travel to the Western Negev. Because those are the vastest sand dunes in Israel and the most preserved. We’ll focus on animals found only here from the entire land.

Firstly, the Negev Tortoise is endemic to the Negev area. Apart from the fact that they are most active during the winter, we know little about them. We do know they are territorial and the Negev Tortoise is mostly active during the fall, winter, and spring. Contrary to most reptiles in the summer, he is a sleep in burrows, usually ones that were abandoned by rodents. The reason for that is the drying up of the Annual flowers in Israel during the summer; that due to its climate form more than 50% from the entire Flora of Israel.

Animals Living in Sand Dunes: Savigny’s Agama

Another reptile that is active during the day is Savigny’s agama. The peculiar name was given to him in honor of a French zoologist, Marie Jules César Lelorgne de Savigny. In 1798 he traveled to Egypt with Emperor Napoleon as part of the French scientific expedition to that country and contributed to the publication of the findings of the expedition in 1809 (Description de l’Egypte).  He wrote about the fauna in the Mediterranean Sea and the Red Sea.

Savigny’s agama on hot days climbs shrubs and bushes and this way distance his body from the hot ground. He hardly ever drinks and most of his water he’s getting from his food like plants and insects, even small lizards. reaching to a total of 25 cm while his tail is about the same length. When he walks he leaves marks on the ground including his tail but when he runs he lifts the tail that does not show on the sand.

The Sand Fish (Scincus Scincus)

My own personal favorite creature that populates the sand dunes in the Western Negev. This peculiar name is due to his ability to move in the sand as if he were swimming in it. Adults usually reach 20 cm in length, including the short tail. The common skink has developed a peculiar surprise way of dealing with the desert heat: it can dive into soft sand. It does this to prevent overheating (as it is cold-blooded) and whenever it feels threatened, especially by its arch-nemesis: the devil-headed Saharan snake.

This skink has a long, wedge-shaped snout with a countersunk lower jaw, shaped much like a basket. Its long, tapered compact body is covered with smooth, shiny scales that may appear only to the untrained eye, and its legs are short and sturdy with long, flattened, and fringed shovel-like feet. The tail is short, tapering to a fine point. The coloration of this species is considered attractive, being yellow-caramel with brown-black cross bands. This lizard also has bead-like eyes so it can close them to keep sand out of its eyes. Similarly, its nostrils are very small to keep all of the sand out of its nose and lungs.

Animals Living in Sand Dunes: The Devil-Headed Saharan Snake

This genus is nocturnal and terrestrial (not known to climb into bushes), often hiding by burying themselves in the sand. Although often described as slow-moving, these snakes are also capable of sidewinding. When doing so, they can move quickly across the sand.

Cerastes species are not known to be particularly ill-tempered (“fairly placid”), but when threatened they will often stand their ground and form C-shaped coils that are rubbed together to produce a rasping or crackling sound, similar to Echis. This is called stridulation. With enough provocation, they will strike from this position.

These snakes are capable of “sinking” quickly down into loose sand, using their keeled, angled and serrated lateral scales in a rocking motion. This process begins at the tail and moves forward until the entire head is buried and only the eyes and nostrils are exposed. They can bury themselves this way whether in an outstretched or a coiled position.

Animals Living in Sand Dunes: Sociable lapwing

Bird lovers from all over the world will dedicated days after days in search of this rare bird. I mean no other than the Sociable Lapwing which is a critically endangered wader in the lapwing family of birds. This species breeds on open grassland in Russia and Kazakhstan. Three to four eggs are laid in a ground nest. Then these birds migrate south through Kyrgyzstan, Tajikistan, Uzbekistan, Turkmenistan, Afghanistan, Armenia, Iran, Iraq, Saudi Arabia, Syria and Turkey, to key wintering sites in Israel, Syria, Eritrea, Sudan, and north-west India. It is a very rare vagrant in western and northern Europe, where this gregarious bird is usually found with northern lapwings. It feeds in a similar way, picking insects and other small prey. Traditionally, a flock spends the winter in the open fields of the famous powerline south of Urim in the northwestern Negev.
