Chelonoidis becki, also known as the Volcán Wolf Giant Tortoise, is a species of tortoise native to the Galápagos Islands. This species is recognized for its impressive size and distinctive saddle-backed shell, which allows it to reach higher vegetation.

Scientific Classification

• Kingdom: Animalia
• Phylum: Chordata
• Class: Reptilia
• Order: Testudines
• Family: Testudinidae
• Genus: Chelonoidis
• Species: C. becki

Common Names

• Volcán Wolf Giant Tortoise

Identification

Description:
Chelonoidis becki is characterized by its large, saddle-backed carapace, which enables the tortoise to extend its neck to browse on higher vegetation. The carapace is typically dark brown or black, with scute growth lines visible on older individuals. The limbs are sturdy and covered in scales, adapted to the rugged terrain of the Galápagos Islands.

Sexual Dimorphism:
Males are generally larger than females, with more pronounced saddlebacks on their shells. Additionally, males have longer tails and concave plastrons, which aid in mating.

Native Origin and Distribution

Geographical Range:
Chelonoidis becki is native to the northern part of Isabela Island in the Galápagos Archipelago, particularly around the slopes of Volcán Wolf.

Preferred Habitat

This tortoise species inhabits arid zones with sparse vegetation, including cacti and shrubs. It can also be found in the more humid highlands, where there is greater vegetation diversity.

Behavior

Feeding Habits:
Chelonoidis becki primarily feeds on cacti, grasses, and other vegetation. The species has also been observed consuming fruits and other plant matter found on the ground.

Predators:
Adult Chelonoidis becki have few natural predators due to their size and tough shell. However, hatchlings and juveniles are vulnerable to predation by introduced species like rats, cats, and dogs.

Reproduction

Breeding Season:
Breeding generally occurs during the warmer, wetter months, typically from January to May.

Reproductive Method:
Females lay eggs in nests dug into the soil. Clutches usually contain 2 to 16 eggs, depending on the size of the female. The eggs incubate for several months before hatching.

Conservation

Extinction Status:
Chelonoidis becki is currently listed as Vulnerable on the IUCN Red List.

Threats:
The species faces threats from habitat destruction, invasive species, and climate change. Human activity and introduced predators continue to impact the survival of young tortoises.

Conservation Measures:
Conservation efforts include habitat protection, breeding programs, and eradication of invasive species on Isabela Island. The Galápagos National Park and other organizations are actively involved in preserving this species.

Economic Importance

Chelonoidis becki has significant ecological and economic importance, particularly in terms of tourism. The species is a key attraction for eco-tourists visiting the Galápagos Islands, contributing to the local economy.
