Where it lives:
mappa oranghi
Distribution and Habitat:
Foresta tropicale secca di Messico e Guatemala.
Size
Può raggiungere i 90 cm di lunghezza e i 2,5 kg di peso.
Behavior
Diurno, trascorre la stagione secca all’interno di una tana sotterranea, concentrando la sua attività in estate durante il periodo delle piogge. I suoi movimenti sono molto lenti, tranne quando sferra attacchi alle sue prede, e si allontana dalla tana solo per brevi periodi.
Reproduction
Per attrarre le femmine i maschi si esibiscono in combattimenti ritualizzati. L’accoppiamento avviene in autunno e le uova, da 2 a 22 deposte a dicembre, schiudono in estate durante la stagione umida.
Diet
Si nutre di piccoli mammiferi, uccelli, rettili e uova. Prima di ingoiarle, mastica le sue prede per permettere al veleno di penetrare e fare effetto.
Did You Know?
La sua pelle è costituita da osteodermi, placche ossee di protezione che gli conferiscono un’apparenza corazzata. Caratteristica condivisa da poche altre specie di rettili, come i coccodrilli.
Threat Level
È minacciato dalla perdita dell’habitat e dalla persecuzione diretta.

LEGEND

  1. CITES: The species is protected by the Washington Convention – also known as CITES – which regulates international trade in wild fauna and flora species. CITES is an agreement among over 160 governments that, through international and national laws, regulates or even prohibits the export, import, sale, and possession of many species and their derivatives such as skins or ivory.

  2. EEP/ESB: The species is part of a European conservation program coordinated by the European Association of Zoos and Aquaria (EAZA), of which the Bioparco is a member. The EEP (Eaza Ex Situ species Programme) includes various actions such as captive breeding for potential releases into the wild, public awareness, and scientific research. The European studbook (ESB) is an inventory aimed at monitoring the status of individuals of a particular species in captivity and generally precedes the EEP.

  3. RED LIST IUCN: The species is included in the Red List of Threatened Species compiled by the IUCN (International Union for Conservation of Nature). This is the most comprehensive inventory that codifies the degree of threat to species globally based on a system of categories and scientifically rigorous quantitative criteria.

WARNING

Due to the documented presence of West Nile Virus in Rome and the Lazio region, we recommend following the measures indicated by the Italian Ministry of Health: Ministero della Salute – West Nile, cosa c’è da sapere.

These measures are intended to reduce the risk of mosquito bites from mosquitoes that can transmit the virus.

We suggest:

  • using mosquito repellent on exposed skin;
  • wearing light-coloured clothing that covers as much skin as possible.

Bioparco has already taken measures to reduce mosquito numbers within the park. Visitors who do not have mosquito repellent with them can receive it free of charge at the entrance.
