Anolis Lizards: The Thriving Lizards of Puerto Rico

Puerto Rico, an island of vibrant biodiversity, is home to an impressive array of Anolis lizard species. These remarkable reptiles, renowned for their adaptability and diversity, have captivating stories to tell.

Overview of the Anolis Genus

Belonging to the Polychrotidae family, Anolis lizards are widely distributed throughout Puerto Rico. With their slender bodies and agile movements, they inhabit a vast range of habitats, from dense forests to urban areas, showcasing their remarkable ability to thrive in various ecosystems.

Habitat Preferences and Unique Characteristics

Anolis cristatellus (Brown Anole)

The Brown Anole reigns supreme in forest edges and gardens, with its mottled brown scales providing camouflage amidst the foliage. It sports a distinctive crest along its back, and its males display flamboyant dewlaps during courtship rituals.

Anolis gundlachi (Green Anole)

In lush forests and mangroves, the Green Anole blends seamlessly with its surroundings thanks to its vivid green coloration. It possesses the ability to change its hue to match its surroundings, enabling it to evade predators and surprise prey.

Anolis krugi (Gray Anole)

Rockier habitats, such as limestone cliffs and caves, are favored by the Gray Anole. Its subdued gray scales provide camouflage against the rocky terrain. This lizard’s diet consists primarily of insects and small invertebrates.

Anolis pulchellus (Marsh Anole)

The Marsh Anole, as its name suggests, frequents wetlands and swamps. Its brown or green scales provide camouflage in the dense vegetation, and its webbed feet allow it to navigate aquatic environments with ease.

Anolis stratulus (Dwarf Anole)

The diminutive Dwarf Anole, found in both forests and urban areas, is the smallest Anolis species in Puerto Rico. Its size and cryptic coloration enable it to evade detection by predators and competitors.

Unveiling the Secrets of Ameiva Lizards

In the vibrant tapestry of Puerto Rican wildlife, Ameiva lizards stand out as fascinating reptiles that play a vital role in the island’s ecosystem. These elusive creatures captivate nature enthusiasts with their sleek bodies, glossy scales, and quick, darting movements.

The Black Ameiva (Ameiva exsul), the only Ameiva species found in Puerto Rico, is a medium-sized lizard with a blackish-brown body. Its scales are iridescent, reflecting light beautifully under the sun. This species is endemic to Puerto Rico and is primarily found in dry, coastal areas.

Ameiva lizards are excellent runners and climbers. They inhabit a variety of habitats, including scrublands, grasslands, and forest edges. These lizards are often found basking in the sun on rocks or logs, or foraging for insects, berries, and other small prey.

Captivating Characteristics:

• Elongated bodies: Ameiva lizards have long, slender bodies that allow them to navigate dense vegetation and crevices with ease.
• Powerful limbs: Their strong legs enable them to leap and bound quickly.
• Prehensile tails: Ameiva lizards can grip objects with their tails, providing them with stability and support while climbing.
• Keel scales: The scales along their backs have a raised keel, which gives them a rough texture.

Intriguing Distribution:

The Black Ameiva is found throughout Puerto Rico, with the exception of the high-elevation central mountain range. It is particularly common in the dry forests of the southern coast and the coastal plains of the north. This species has also been introduced to other Caribbean islands, including St. Thomas and St. Maarten.

By understanding the characteristics and distribution of Ameiva lizards, we gain a deeper appreciation for the remarkable diversity of Puerto Rican wildlife. These fascinating reptiles play an important role in their ecosystem and add to the island’s unique natural heritage.
