Explain why there are fewer eggs produced by mammals in comparison to amphibians and reptiles? Eggs from amphibians and reptiles are much smaller than mammals. Embryos from mammals require more time and care to develop. Amphibians and reptiles can only reproduce once in their life cycle. There are more space to lay eggs for reptiles and amphibians.

Difference between amphibians and reptiles: Among the animals in the animal kingdom, amphibians and reptiles are the most frequently interchanged. But did you know that even in early 1800, there had already been studies showing that the two are of different classes?

A zoologist named Josephus Nicolaus Laurenti termed “Reptilia” as a separate division from “Amphibia“. Since then, it became clearer that they are different in many aspects. Let’s explore the difference between amphibians and reptiles and also similarities between them in this article.

The word “amphibia” refers to a “double life” which in turn refers to the ability of the members of Class Amphibia to live both in water and on land. Basically, the Class Amphibia is composed of three orders: Anura (includes frogs and toads), Urodela (includes salamanders), and Apoda (caecillians).

Amphibians are unable to regulate their body temperature.

After hatching from eggs, they undergo through a larval stage which can range from just 10 days up to 20 years (for some species)!

During their larval stage, amphibians breathe through their gills but later on develop their lungs as they move on to land.

The impact of the Crusades may thus be summarised in general terms as:

an increased presence of Christians in the Levant during the Middle Ages.

the development of military orders.

a polarisation of the East and West based on religious differences.

the specific application of religious goals to warfare in the Levant, Iberian peninsula, and Baltic region, in particular.

the increased role and prestige of the popes and the Catholic Church in secular affairs.

the souring of relations between the West and the Byzantine Empire leading, ultimately, to the latter's destruction.

an increase in the power of the royal houses of Europe.

a stronger collective cultural identity in Europe.

an increase in xenophobia and intolerance between Christians and Muslims, and between Christians and Jews, heretics and pagans.

an increase in international trade and exchange of ideas and technology.

an increase in the power of such Italian states as Venice, Genoa, and Pisa.

the appropriation of many Christian relics to Europe.

the use of a religious historical precedent to justify colonialism, warfare and terrorism.
