Tropidurus indefatigabilis

The Santa Cruz lava lizard (Microlophus indefatigabilis) is a species of lava lizard endemic to the Galapagos island of Santa Cruz. [2]

Contents

Description

They are identifiable by a brown body with scattered black and white blotches with a distinctive red and black throat and a black chest. Females have a more uniform brown body, a bright orange face, and a black mark at shoulder level. The species is able to shed its tail without mortal injury. [3] The

Sexual dimorphism

Harems are kept, and are competed for by males using a pushup ritual to avoid physical injury. Males have a higher stamina and greater body size compared to the female. [4]

Distribution

Endemic to Santa Cruz Island, it is found within volcanic rock areas, dry shrublands, dry grasslands, deciduous forests, and urban areas, and prefers shaded locations. [3]

Microlophus is a genus of tropidurid lizards native to South America. Around 20 species are recognized and 10 of these are endemic to the Galápagos Islands, where they are commonly known as lava lizards. The remaining, which often are called Pacific iguanas, are found in the Andes and along the Pacific coasts of Chile, Peru, and Ecuador.

<span class="mw-page-title-main">Marine iguana</span> Species of marine reptile endemic to Galapagos Islands

The marine iguana, also known as the sea iguana, saltwater iguana, or Galápagos marine iguana, is a species of iguana found only on the Galápagos Islands (Ecuador). Unique among modern lizards, it is a marine reptile that has the ability to forage in the sea for algae, which makes up almost all of its diet. Marine iguanas are the only extant lizard that spends time in a marine environment. Large males are able to dive to find this food source, while females and smaller males feed during low tide in the intertidal zone. They mainly live in colonies on rocky shores where they bask after visiting the relatively cold water or intertidal zone, but can also be seen in marshes, mangrove swamps and beaches. Large males defend territories for a short period, but smaller males have other breeding strategies. After mating, the female digs a nest hole in the soil where she lays her eggs, leaving them to hatch on their own a few months later.

<span class="mw-page-title-main">Galapagos land iguana</span> Species of lizard

The Galápagos land iguana is a very large species of lizard in the family Iguanidae. It is one of three species of the genus Conolophus. It is endemic to the Galápagos Islands, in the dry lowlands of the islands of Fernandina, Isabela, Santa Cruz, North Seymour, Baltra, and South Plaza.

<i>Conolophus marthae</i> Species of reptile

Conolophus marthae, the Galápagos pink land iguana, is a species of lizard of the family Iguanidae. This critically endangered iguana is native only to the Wolf Volcano in northern Isabela Island of the Galápagos Islands (Ecuador). It has a pink body with some dark stripes, prompting some to call it the pink iguana or the Galápagos rosy iguana. The species was first discovered in 1986 and was identified as a separate species, distinct from the Galápagos land iguana, early in 2009. This species is the only example of ancient diversification in the genus Conolophus.

Microlophus delanonis, the Española lava lizard or Hood lava lizard, is endemic to the Galapagos island of Española. The species is commonly attributed to the genus Microlophus but has been attributed to the genus Tropidurus.

<i>Microlophus albemarlensis</i> Species of lizard

Microlophus albemarlensis, the Galápagos lava lizard, also known as the Albemarle lava lizard, is a species of lava lizard. It is endemic to the Galápagos Islands, where it occurs on several islands in the western archipelago: the large islands Isabela, Santa Cruz, Fernandina, Santiago and Santa Fe, as well as several smaller islands: Seymour, Baltra, Plaza Sur, Daphne Major and Rábida. It is the most widespread of the Galápagos species of Microlophus, the others only occurring on single islands. Some authors however, consider populations on Santiago, Santa Cruz, and Santa Fe to be distinct species. The species is commonly attributed to the genus Microlophus but has been historically placed in the genus Tropidurus.

<i>Microlophus bivittatus</i> Species of lizard

Microlophus bivittatus, the San Cristóbal lava lizard, is a species of lava lizard endemic to San Cristóbal Island in the Galápagos Islands. The species is commonly attributed to the genus Microlophus but has been attributed to the genus Tropidurus. They are currently under threat by invasive cats on the island. The lizard is also closely related to the Microlophus occipitalis which radiated off of the bivittatus.

<i>Microlophus occipitalis</i> Species of lizard

Microlophus occipitalis, colloquially known as the knobbed Pacific iguana, is a lizard included within the Tropiduridae family. It is a member of the Microlophus genus and thus also considered a lava lizard. The knobbed Pacific iguana is found primarily in Western Peru and Ecuador, lining the coasts. The habitats of the knobbed Pacific iguana can be considered to be both broad and diverse as they are typically found in many different places such as beaches, lomas, and all the way to desert regions. This diversity is furthered as these lizards can also be found in open areas, between rocks, or bushes.

<i>Xylocopa darwini</i> Species of bee

Xylocopa darwini, the Galápagos carpenter bee, is the only native species of bee in the Galápagos Islands, to which it is endemic. Altogether, only three species of bee are found in the islands. This species found on 75% of the largest islands. It is sexually dimorphic and is known for its complex behavior. As the only native bee, Xylocopa darwini serves as an important primary pollinator within the plant-pollinator network of the archipelago.

<i>Microlophus barringtonensis</i> Species of lava lizard

Microlophus barringtonensis or the Santa Fe lava lizard is a species of lava lizard or a population of Microlophus albemarlensis. It inhabits Santa Fe island in the Galápogos. It is the only lava lizard on Santa Fe. It is extremely common.

<i>Microlophus jacobi</i> Species of lizard

The Santiago lava lizard is a species of lava lizard in the family Tropiduridae. They are endemic to the Galapagos islands of Santiago, Bartolomé, Rábida and a few islets. They are also the only lava lizards present on these islands. This species was formerly considered a subpopulation of the Galápagos lava lizard, but is now widely considered as a distinct species.
