About Causus Rhombeatus Snake:

Causus rhombeatus, commonly known as the rhombic night adder, is a venomous viper species endemic to subsaharan Africa. No subspecies are currently recognized.

Description:

With an average total length (body + tail) of 60 cm (24 in), this is the largest member of the genus Causus.

The longest individual ever recorded was a male, 93 cm (37 in) in total length, collected in eastern Zimbabwe.

The head has a snout that is relatively blunt (i.e., more rounded than in other members of this genus), on the sides of which the nostrils are positioned.

The circumorbital ring consists of 2-3 preoculars, 1-2 postoculars, and 1-2 suboculars that separate the eye from the supralabials.

The temporal scales usually number 2+3, sometimes 2+4, but very rarely 2+2 or 3+3.

There are 6 supralabial scales, very rarely 7.

The sublabial scales usually number 7 or 10, rarely 8, and very rarely 11, 12 or 13. The first 3-4 sublabials are in contact with the anterior chin shields.

The posterior chin shields are small and often indistinguishable from the gulars.

Geographic range:

Savannas of subsaharan Africa from Nigeria east to Sudan, Ethiopia, Somalia and Kenya, south through Tanzania, Uganda, Rwanda, Burundi, DR Congo, Angola, Zambia, Malawi, Zimbabwe,

northern Botswana, Mozambique, Eswatini, and eastern South Africa to Riverdale in the Western Cape Province.

No type locality is listed.

Behavior:

This is an active species that can often move relatively quickly—up to an estimated speed of 92 cm per second (3 feet per second).

They are usually found on the ground, but have no trouble climbing or swimming.

They are largely nocturnal, but are often seen basking in the early morning or late afternoon.

However, Harper (1963) reported collecting a dozen specimens that were all active during the heat of the day.

Feeding:

The diet consists mainly of toads, but it also includes frogs and small mammals.

Reproduction:

Females produce an average clutch of two dozen eggs that require a lengthy incubation period of approximately four months.

The hatchlings are 10–12.5 cm (3.9–4.9 in) in total length and feed on tiny frogs and toads.
