De schauensee's anaconda
The Dark-spotted anaconda (Eunectes deschauenseei) is a semi-aquatic boa species endemic to northeastern South America. Like all boas, it is a non-venomous constrictor.
Adult males of this species measure 130-211 cm (51-83 in) and adult females 120-231 cm (47-91 in) in snout–vent length.
Dark-spotted anacondas are found in South America, in northern Brazil (the Pará and Amapá states), and in French Guiana. There they live in swampy, seasonally flooded freshwater areas of the Amazonian savanna.
Dark-spotted anacondas spend all their lives in and around water and are proficient swimmers and divers. When not in water they will climb up in trees where they also can hunt their prey or just sunbathe hanging from large branches above bodies of water.
Little information is known about the diet habits of this species.
The breeding time of Dark-spotted anacondas probably occurs from autumn to spring (May to December). Gestation may last as long as 9 months. Litter size among 5 gravid females ranged from 3 to 27 (mean 10.6) young. Newborns measure 29-53 cm (11-21 in) in snout–vent length.
There are no major threats facing the Dark-spotted anaconda. The savanna habitat where these snakes occur is highly threatened by agricultural expansion, but the threat posed to this species is not known.
The IUCN Red List and other sources don’t provide the number of the Dark-spotted anaconda total population size. Currently, this species is classified as Least Concern (LC) on the IUCN Red List.
