Oplurus lizards are part of the family Opluridae, which is a group of small to medium-sized lizards native to Madagascar.

They belong to the infraorder Iguania, which also includes iguanas and chameleons.

Oplurus lizards are characterized by their long, slender bodies, which can grow up to 20 centimeters in length.

These lizards are primarily herbivores, feeding on leaves, flowers, and fruits.

Classification

Classification of Oplurus is a bit complex, but let's break it down. The genus Oplurus comprises two distinct clades: the Spiny-tailed arboreal clade and the Saxicolous (rock dwelling) clade.

These clades are part of the larger group called Squamata, which includes lizards. Oplurus is also related to the iguana family, but it's now recognized as a distinct family, Opluridae, which was previously considered part of the Iguanidae family.

Here's a simplified breakdown of the classification hierarchy:

  • Eukaryota
  • Animalia
  • Reptilia
  • Squamata
  • Opluridae
  • Oplurus

Note that the classification hierarchy goes all the way back to the kingdom level, but for simplicity, we've stopped at the genus level.

Species

The Oplurus genus is home to six recognized species, which can be grouped into two distinct clades. These clades are the spiny-tailed arboreal clade and the saxicolous (rock dwelling) clade.

The spiny-tailed arboreal clade is a notable group, but we don't know much about its characteristics beyond its name.

Some species within this clade may have a larger body size compared to others.

The saxicolous clade, on the other hand, consists of species that live in rocky areas.

A recent discovery on the Comoro archipelago led to the naming of a new species, Oplurus comorensis. However, molecular phylogeny research suggests that this species may not be distinct enough to warrant full species status.

Here's a summary of the two clades:

Taxonavigation

Taxonavigation helps us understand the classification of a species, and for Oplurus cyclurus, we can follow its taxonomic path.

The species Oplurus cyclurus belongs to the superregnum Eukaryota, which includes all eukaryotic organisms.

Eukaryota is further divided into several cladus, including Amorphea, Obazoa, Opisthokonta, Holozoa, Filozoa, Choanozoa, and others.

At the regnum level, Oplurus cyclurus is classified as Animalia, which includes all animals.

Within Animalia, we have several subregna, including Eumetazoa, which is the subregnum of Oplurus cyclurus.

Eumetazoa is further divided into several cladus, including ParaHoxozoa, Bilateria, Nephrozoa, and others.

Moving down the taxonomic hierarchy, we find that Oplurus cyclurus belongs to the superphylum Deuterostomia, which includes all deuterostomes.

Deuterostomia is further divided into the phylum Chordata, which includes all chordates.

Within Chordata, we have several cladus, including Olfactores, Vertebrata, Gnathostomata, Eugnathostomata, Osteichthyes, Sarcopterygii, Rhipidistia, Tetrapodomorpha, Eotetrapodiformes, Elpistostegalia, Stegocephali, Tetrapoda, Reptiliomorpha, Amniota, Sauropsida, and others.

Here is a simplified taxonomic hierarchy for Oplurus cyclurus:

  • Eukaryota
  • Animalia
  • Eumetazoa
  • Deuterostomia
  • Chordata
  • Vertebrata
  • Gnathostomata
  • Osteichthyes
  • Squamata
  • Iguania
  • Pleurodonta
  • Opluridae
  • Oplurus
  • Oplurus cyclurus

Oplurus cyclurus is specifically classified as a member of the family Opluridae, genus Oplurus, and species Oplurus cyclurus.

Vernacular Names

Vernacular names are an essential part of classification, as they provide a common language for people to refer to different species.

Pages that list taxonavigation templates often also include vernacular names, which can be found in the same section as the template.

Taxonavigation templates help organize and categorize species, and vernacular names are a useful addition to this process.

Pages with vernacular names are typically listed in a separate section, making it easy to find and access this information.

  • Taxonavigation templates and vernacular names are often found together on the same page.
  • Pages with vernacular names are easily identifiable and accessible.

Relation to Iguanas

Swifts are often confused with iguanas, but they belong to a distinct family.

The Opluridae family, which includes swifts, is not closely related to iguanas.

Prior to 1996, swifts were actually considered part of the Iguanidae family, but they're now recognized as a separate group.

Frequently Asked Questions

How do you care for an Oplurus cyclurus?

To care for an Oplurus cyclurus, provide a warm and humid environment with a temperature range of 25-30°C (77-86°F) and a basking area, along with UVB lighting. This arboreal environment should mimic the open forest habitat of its natural range.

How big are spiny-tailed iguanas in Madagascar?

Spiny-tailed iguanas in Madagascar typically grow to 9.8-15.4 inches (25-39 cm) in length. They have a distinctive greyish color with spotted patterns and enlarged, spinous scales on their back, tail, and legs.

What is the giant spiny-tailed lizard in Madagascar?

The Oplurus cyclurus, also known as the giant spiny-tailed lizard, is a widespread endemic species found in dry areas of southern and western Madagascar. It's a unique iguanid that can adapt to various habitats, from forests to savannahs.
