Psammophilus Habitat and Behavior Explained

Psammophilus are primarily found in the wild in the deserts and dry scrublands of India and Sri Lanka, where they bask in the warm sun on rocky outcrops.

These lizards are diurnal, meaning they're active during the day and rest at night, often in burrows or under rocks. They can also be found in dry forests and grasslands with rocky terrain.

Psammophilus are known to be solitary animals, only coming together for mating. They have a complex communication system, using a variety of sounds, visual displays, and even scent markings to convey information.

In the wild, Psammophilus are carnivores, feeding on insects, spiders, and other small invertebrates.

The Psammophilus lizard has a distinctive large head that is elongated and depressed, especially in adult males.

Its snout is longer than the diameter of the orbit, which is a key characteristic to look out for.

The lizard's upper head scales are unequal and smooth or obtusely keeled, with larger scales on the brow than on the back of the head.

A clear and sharp edge is visible on the canthus rostralis and supraciliary, and two small separated spines or groups of spines are often present above the ear.

The diameter of the tympanum is half or a little more than half that of the orbit, which is a notable feature.

The lizard's body is slightly flattened, with dorsal scales that are small, uniform, smooth, or feebly keeled in adults, and strongly keeled in young ones.

The dorsal crest is reduced to a ridge of enlarged scales, and ventral scales are as large as the dorsals, but smooth.

Around the middle of the body, there are between 115 and 150 scales, and the gular scales are a little smaller than the ventral scales.

Four or five enlarged scales occur on the chin parallel with the anterior labials, separated from them by two rows of scales.

The legs are strong, covered with uniform, keeled scales, and the hind limb reaches the ear or the rear end of the eye when extended forward.

In adults, the tail is slightly flattened and covered with keeled scales, which are larger below than above, and is distinctly swollen at the base in males.

The Psammophilus lizard is quite the social creature, with males often basking openly on exposed rocks. They even show off with head push-up displays to impress their peers.

In fact, the larger males tend to take up higher perch positions, giving them the best view of their surroundings. This is likely a strategy to assert dominance and attract females.

When birds fly overhead, Psammophilus lizards will flatten their bodies to remain hidden, suggesting they're not too fond of aerial predators. Densities of about 90 lizards per hectare have been noted in certain areas, indicating a relatively high population density in these regions.

Males of this species bask openly on exposed rocks, showcasing their impressive head push-up displays.

These displays are a clear indication of dominance, with larger males taking up higher perch positions to assert their authority.

They also have a unique way of coping with overhead bird traffic - by flattening their bodies to blend in with their surroundings.

Densities of about 90 lizards per hectare have been observed in certain areas, highlighting the social nature of this species.

The habitat of this species is widespread across several Indian states.

Bihar, Orissa, and Madhya Pradesh are some of the key regions where it can be found.

It's also common in Karnataka, Andhra Pradesh, and Goa.

The species has a strong presence in Kerala and Tamil Nadu as well.

Psammophilus can be found in southern India, specifically south of about 16°N latitude. This region includes the Western Ghats, where they inhabit hilly areas at elevations up to 6000 ft above sea level.

The Nilgiris, a part of the Western Ghats, is home to this species, with some areas having a very common presence. In fact, it was noted by M.A. Smith that they are particularly common near Bangalore.

This species is listed as an IUCN Red List least concern species, indicating that it is not currently threatened with extinction.

The geographic range of the Psammophilus dorsalis is quite fascinating. They can be found in southern India, specifically south of about 16°N latitude.

In the Western Ghats, they inhabit the hilly regions at altitudes up to 6000 ft above sea level in the Nilgiris. This region is home to some of the most beautiful and diverse landscapes in the country.

The Nilgiris, South Arcot, and Nallamalai Hills are all part of their habitat, where they thrive in the unique environment. It's not uncommon to spot them in these areas, particularly near Bangalore.

Here's a breakdown of their geographic range:

The hematological and plasma biochemistry of Psammophilus blanfordanus has been studied.

Psammophilus blanfordanus, a species of lizard, has been analyzed for its hematological parameters.

Hematocrit values in Psammophilus blanfordanus range from 28.5 to 34.5%.

The species' hematocrit values are within the normal range for lizards.

Red blood cell count in Psammophilus blanfordanus is between 3.6 and 5.3 x 10^12/L.

White blood cell count in Psammophilus blanfordanus is between 1.5 and 3.5 x 10^9/L.

The plasma biochemistry of Psammophilus blanfordanus has also been examined.

Albumin levels in Psammophilus blanfordanus range from 1.5 to 2.5 g/dL.

Total protein levels in Psammophilus blanfordanus range from 4.5 to 7.5 g/dL.

Alkaline phosphatase levels in Psammophilus blanfordanus are within the normal range for lizards.

These studies provide valuable insights into the hematology and plasma biochemistry of Psammophilus blanfordanus.
