Peru possesses a coastal plain running along its Pacific shore for 2,400 km (1,500 miles).  The country borders Colombia and Ecuador in the north, Brazil in the east, and Chile and Bolivia in the south. Its territory is almost four times as large as Germany. More than 50% of the surface area is covered with rainforest.

As a result of the geographical situation, the climatic conditions prevailing in this country are highly variable. The most important zones include the arid coastal region (costa), the Andean highlands (sierra) whose peaks are covered by eternal snow above 5,000 m (16,400 ft), and the selva, the Amazonian lowlands in eastern Peru covered with subtropical and tropical rainforest.

The selva is the home of the Peruvian Boa c. constrictor. This rainforest region occupies almost 60% of Peru’s total surface area. The average annual temperature is 26° C (79° F), and the annual precipitation nearly reaches levels of 3,800 mm/m² (150 in/m²). The rains last from December to April, but heavy rainfall is by no means exceptional during the dry season.

Iquitos is the largest city of this region.  Its name cannot be separated from the Peruvian Boa c. constrictor kept in private collections.

It also deserves being mentioned that Boa c. constrictor equally occurs in the surroundings of Olmos, a city situated west of the Andes, i.e. within the distribution area of Boa c. ortonii! These snakes cannot be distinguished from members of the same subspecies living in the Iquitos region. Apparently, the local Andes are neither sufficiently high nor as impassable as to form a barrier for Boa constrictors. We therefore may assume that the Olmos region also harbors transitional forms between Boa c. constrictor and Boa c. ortonii.

Until the late 1990s, Peruvian Boa constrictors were rarely exported legally. Only after this period, the export of so-called farm-bred snakes was legalized, and Peruvian red-tailed boas were  seen in captivity more frequently since. The exports usually took place via Iquitos and Pucallpa, and the exported animals almost exclusively came from that regions, too.

However, the imported boas were mainly wildcaught specimens who were mislabelled as farmbred ones. By the way, this was not the fault of the European dealers who had ordered the animals. The farmbreeders violated the regulations.

To our knowledge these breeding farms were shut down several years ago. Therefore the export of Boa c. constrictor from Peru came to an end. Since the mortality rate in the imported Peruvian redtail boas is very high many of the imported animals are dead meanwhile.

The result: The demand exceeds the supply by far again.

The Boa c. constrictor found in the various parts of Peru are difficult to distinguish from each other. Boa constrictors from the Iquitos region in northeast Peru absolutely match members of the same species collected near Pucallpa in the east, or specimens from the surroundings of Madre de Dios in the south - although Iquitos and Madre de Dios are separated by a distance of approximately 2,000 km (1,240 miles).


Peruvian red-tailed boas can usually be identified by their ochre ground coloration and hourglass-shaped saddle patches. In our opinion, these animals possess the highest growth potential observed in any Boa c. constrictor: They can weigh 100 g. (3.5 oz) at birth, whereas ‘normal’ Boa c. constrictor only weigh 60-80 g (2-2.8 oz).

In spite of these typical characteristics, it would be a mistake to believe that animals showing this appearance are automatically Peruvians. As we have already mentioned, Colombian Boa c. constrictor from the Leticia region have the same look. The same applies to the red-tailed boas inhabiting the eastern Amazonian Basin of Ecuador.

This group of Boa c. constrictor (i.e. the animals from Peru, Leticia (Colombia) and Ecuador) show a coloration and pattern which differ so strikingly from Suriname and Guyana red-tailed boas that they should not be crossed with the aforesaid snakes under any circumstances.

As a conclusion, it deserves being mentioned that Peruvian Boa c. constrictor were erroneously classified as Boa c. ortonii right into the late 1990s. However, this error has been corrected.
