Reptiles

Description
Description

Reptiles, under the class Reptilia, are cold-blooded vertebrates characterized by their dry, scaly skin, which enables them to thrive in various habitats, from deserts to rainforests. Their evolutionary lineage dates back to the late Carboniferous period, over 300 million years ago. Reptiles were the dominant terrestrial vertebrates during the Mesozoic era, the age of dinosaurs. Modern reptiles include snakes, lizards, turtles, crocodilians, and tuataras. They exhibit diverse reproductive strategies, from egg-laying to live birth. Reptiles play crucial ecological roles, often as predators and prey, and their adaptive resilience has allowed them to persist through multiple mass extinctions.

Anatomy
Anatomy

Reptiles are a diverse group with varying anatomies, but they share key traits. They have scaly, waterproof skin, which helps retain moisture and withstand different environments. Most reptiles are ectothermic, relying on external heat sources to regulate body temperature. They have strong, muscular bodies adapted for crawling, climbing, or swimming. Limb structure varies: snakes lack limbs, while lizards and crocodilians have well-developed ones. Reptiles don't have vocal cords for speech, but some can hiss or make sounds by expelling air. They typically have sharp senses, like excellent vision in many lizards and heat-sensing pits in some snakes for detecting prey.

Human Interaction
Human Interaction

Humans and reptiles have a complex relationship. Historically, reptiles have been both revered and feared, appearing in various mythologies as symbols of power or evil. In modern pop culture, reptiles like dinosaurs and dragons captivate audiences in films like "Jurassic Park" and "Game of Thrones."

However, human activities like habitat destruction and climate change pose significant threats to many reptile species. Conservation efforts are crucial, with initiatives like habitat protection, breeding programs, and legislation to prevent illegal trade. Understanding and respecting these creatures is vital, as they play crucial roles in ecosystems and contribute to our planet's biodiversity.

Common Questions
Common Questions
What do reptiles eat?

Reptiles are typically carnivores and feed on eating other animals like insects, mollusks, birds, frogs, mammals, fishes, or sometimes other reptiles. Some reptile species like land tortoises are vegetarians and eat leaves, grass, or cactus while the marine iguana dives into the sea to obtain seaweed for consumption.

Why do reptiles shed?

Reptiles shed their skin so that they can continue to grow. When they shed, reptiles grow a new layer of skin underneath their old skin and then shed their old one. When they shed their skin reptiles also get rid of any parasites during the process. The process of shedding is referred to as sloughing.

When did reptiles first appear?

Reptiles first appeared 315 million years ago during the time period known as the Late Carboniferous Period. This time period is also referred to as the Pennsylvanian and the Coal Age. The first reptile is considered to be the Hylonomus lyelli and is also the first animal known to have fully adapted to life on land.

Dilophosaurus (Dilophosaurus wetherilli)
Scale illustration of an average Dilophosaurus compared to a person

The Dilophosaurus is a theropod dinosaur that lived in North America during the Early Jurassic. In 1940 three skeletons were discovered in northern Arizona, and its genus name, ”two-crested lizard”, honors John Wetherill, a Navajo councilor. It was an active and bipedal species that may have hunted both large and small animals as well as fish. While smaller than some later theropods, the Dilophosaurus was one of the earliest large predatory dinosaurs; it was slender and lightly built with a proportionally large skull. The skill was narrow with a pair of longitudinal, plate-shaped crests.

The Dilophosaurus had an overall length between 16’-20’ (4.88-6.1 m), standing height of 5.7’-7.4’ (1.75-2.25 m), and body width of 15.75”-23.6” (40-60 cm). The weight of the Dilophosaurus was between 650-1,000 lb (295-454 kg).

Loggerhead Sea Turtle (Caretta caretta)
Comparison illustration of the size of a Loggerhead Sea Turtle to other turtles and a person

Known as the largest of the hard-shelled turtles, the Loggerhead Sea Turtle (Caretta caretta) is an oceanic turtle with a broad habitat range with populations found in the Atlantic, Pacific, and Indian Oceans. Within this large distribution, it prefers to dwell in shallow, open waters of coastlines and will travel far to reach these desired habitats. The Loggerhead Sea Turtle is omnivorous and considered a keystone species due to its diet, providing food for other animals at the bottom of the ocean through its expelled waste. Its size also makes it the second largest existing turtle following the Leatherback Sea Turtle.

The Loggerhead Sea Turtle has a carapace length between 30”-42” (76-107 cm), carapace width of 24”-33.5” (61-85 cm), body height of 12.6”-18.1” (32-46 cm), and weight in the range of 154-375 lb (70-170 kg). The typical lifespan of the Loggerhead Sea Turtle is between 45-60 years in the wild and 50-77 years in captivity.

The Spectacled caiman has the ability to change its skin color and darken it during the winter months. They can be found in Brazil, Colombia, Costa Rica, Ecuador, El Salvador, and Mexico. The Spectacled Caiman lives in rivers, lowland wetlands, and still waters. They typically hunt at night and eat birds, fish, amphibians, insects, and small mammals. They are not considered endangered and have a lifespan of 75 years in the wild.

The Spectacled Caiman has an overall length between 3.6’-8.2’ (1.1-2.5 m), body width of 5.9”-13.8” (15-35 cm), body height of 5.5”-11.8” (14-30 cm), and weight between 30-132 lb (14-60 kg). The typical lifespan of the Spectacled Caiman is between 30-70 years.

Deinonychus (Deinonychus antirrhopus)
Size comparison drawing of the Deinonychus compared to a person

The Deinonychus, ”terrible claw” in Greek, is a dromaeosaurid theropod dinosaur. It is an active and agile predator with a small body, sleek horizontal posture, ratite-like spine, and enlarged raptorial claws on the feet. ”Terrible claw” is in reference to the large and sickle-shaped talon on the second toe of each hind foot. It lived in the early Cretaceous Period, and its fossils have been recovered from the US States of Montana, Utah, Wyoming, and Oklahoma. With John Ostrom’s study of the Deinoychus in the late 1960s, he revolutionized the way scientists thought about dinosaurs- igniting the debate on whether dinosaurs were warm-blooded or cold-blooded.

The Deinonychus had an overall length between 9’-16’ (2.74-4.88 m), standing height of 2.8’-4.75’ (.85-1.45 m), and body width of 9.4”-16.5” (24-42 cm). The weight of the Deinonychus was between 160-220 lb (73-100 kg).

Bog Turtle (Glyptemys muhlenbergii)
Size comparison drawing of the Bog Turtle compared to other small reptile species

The Bog Turtle (Glyptemys muhlenbergii) is the smallest turtle in North America, commonly found in the eastern United States. It prefers open habitats with slow-flowing water such as fens, bogs, meadows, or sedge marshes. The bog turtle is omnivorous and has a low reproduction rate, making it considered a threatened species. Its skin and carapace are black or dark brown, while its head, neck, and limbs show yellow or orange spots. Besides, each side of the neck shows distinctive yellow-orange or red spots. This coloration is used to distinguish it from the spotted turtle. The bog turtle has a domed and rectangular-shaped carapace, narrowing towards the head and widening towards the tail.

The Bog Turtle has a carapace length between 3”-3.5” (7.6-8.9 cm), carapace width of 2.36”-2.75” (6-7 cm), body height of 1.4”-1.73” (3.5-4.4 cm), and weight in the range of .2-.24 lb (.09-.11 kg). The typical lifespan of the Bog Turtle is between 20-30 years in the wild and 40-60 years in captivity.
