Difference between Amphibians and Reptiles
The two separate types of ectothermic animals known as amphibians and reptiles each have their own unique biology, anatomy, behavior, and habitat. Here are 30 variations between reptiles and amphibians:
1. Class:
Amphibians are members of the Amphibia class.
The class Reptilia includes all reptiles.
2. Skin:
Amphibians have skin that is supple, wet, and porous, allowing them to breathe through it.
Reptiles have hard, dry, and scaly skin that serves as a barrier of defense and prevents water loss.
3. Skin Gland:
Amphibians have glands that produce mucus and venom on their skin.
Mucus and poison glands are absent from the skin of reptiles.
4. Types of Limbs:
Most amphibians have webbed feet or limbs that are designed for both swimming and jumping.
Reptiles have terrestrial limbs with claws, or in the case of aquatic reptiles, flippers.
5. Eggs:
To prevent desiccation, jelly-covered, soft eggs laid by amphibians need a damp environment.
Reptiles produce eggs with tough or leathery shells that can last in dry environments.
6. Life Stages:
Tadpoles, the aquatic larval stage of an amphibian, often develop into adults.
Reptiles normally do not go through a unique aquatic larval stage when they emerge from their eggs as miniature replicas of the adult.
7. Metamorphosis:
Amphibians completely transform, changing their body shape, developing new limbs, and frequently losing their gills.
Reptiles don't completely transform over their lifetimes and keep the same body types.
8. Respiration:
Amphibians mostly breathe through their skin, gills, and (in some species) lungs.
Reptiles do not breathe through their skin; instead, they breathe via their lungs.
9. Reproductive Behavior:
Amphibians frequently engage in amplexus (a mate-embracing gesture) in or around water bodies.
Although reptiles exhibit a variety of reproductive strategies, they normally do not need water to procreate.
10. Favored Habitat:
Amphibians need water for reproduction and are frequently found in wet or aquatic situations.
While certain species of reptiles can only live in watery or semi-aquatic habitats, most are adaptable to dry terrestrial environments.
11. Thermoregulation:
Ectothermic, or the ability to regulate one's body temperature, is a trait of amphibians.
Although they are similarly ectothermic, reptiles are better at controlling their body temperature since they frequently sunbathe.
12. Habits:
Amphibians tend to be more active at night (nocturnal) or when it's wet outside.
Diurnal (active throughout the day), reptiles can live in dry environments.
13. Vocalization:
Croaks, trills, and chirps are some of the vocalizations made by amphibians like frogs.
Even while some kinds of reptiles may hiss or make other noises, they are normally silent.
14. Lifespan:
Amphibians often live less time than reptiles do.
15. Osmoregulation:
Amphibians actively regulate the amount of water in their body, making them osmoregulators.
Because they enable their internal salt content to match that of their environment, reptiles are osmoconformers.
16. Feeding:
Amphibians often eat meat and eat insects and other tiny prey, especially in their larval stages.
The diet of reptiles is more diverse, consisting of herbivores, carnivores, and omnivores, depending on the species.
17. Teeth:
Amphibians typically lack teeth altogether or have weak, basic teeth.
With differences like fangs for poisonous snakes and crushing teeth for herbivorous turtles, reptiles have more specialized teeth.
18. Parental Care:
In general, amphibians give their young little to no parental care.
Some reptiles show maternal behavior, such as watching over eggs or shielding young.
19. Water Dependency:
Amphibians have a porous skin that easily loses water, making them more water-dependent than other animals.
Reptiles have less water-dependent skin and are better adapted to drier environments.
20. Circulatory System:
The heart of an amphibian normally consists of three chambers.
Depending on the species, reptiles either have a three- or four-chambered heart.
21. Fossorial adaptations:
Some reptiles have unique adaptations for living in burrows and other underground habitats.
Specialized fossorial adaptations are less common in amphibians.
22. Hibernation:
During the winter, a lot of amphibians hibernate.
Although certain reptiles also hibernate, amphibians exhibit this habit more frequently.
23. Longevity:
In general, reptiles live longer than amphibians do.
24. Venom:
Several reptiles have the ability to create and distribute venom through specialized glands and fangs, including several snakes and lizards.
Amphibians don't make venom to hunt prey.
25. Tail Regeneration:
If a lizard loses its tail, it may be able to grow one back.
Salamanders and other amphibians can regenerate their tails.
26. Scales:
Reptiles have scales covering their body that act as both a barrier and a water-retention aid.
Amphibians have skin that is more porous and lack scales.
27. Body Temperature Regulation:
Reptiles can withstand a wider variety of temperatures and have a more effective system for controlling their body temperature.
Amphibians have more limited temperature tolerances and are more sensitive to temperature changes.
28. Fertilization:
External, aquatic fertilization frequently takes place in amphibians.
Internal fertilization occurs in many reptiles, and males often use unique reproductive organs like hemipenes.
29. Size:
The size range of reptiles is much broader, ranging from tiny geckos to enormous crocodiles.
Amphibians have fewer large species and are typically smaller in size.
30. Teeth Replacement:
Reptiles frequently replace their teeth during the course of their lives, either continually or infrequently.
Amphibians normally do not grow new teeth to replace lost ones.
These variations illustrate the numerous adaptations and traits that set amphibians apart from reptiles, indicating the diversity of their ecological functions and evolutionary pasts.
