Body Covering and Characteristics

Class Reptilia has dry, scaly skin as its body covering.

Parental Care

Crocodilians exhibit a high level of parental care, unlike other reptiles, which is characterized by guarding their eggs and young.

Kidneys and Water Conservation

Reptiles possess metanephric kidneys, which are adapted for water conservation.

Heart Structure

Crocodilians have a four-chambered heart.

Respiration

Reptiles respire using lungs.

Cranial Nerves

The typical number of pairs of cranial nerves in the brain of Class Reptilia is 12.

Skull Characteristics

The group of reptiles characterized by a skull with no openings in the temporal area behind the orbit is anapsids.

Diapsids and Synapsids

Diapsids are distinguished from synapsids by having two openings in the temporal area of the skull.
A distinguishing feature of synapsids is the presence of one opening in the temporal area of the skull.

Amniotes

A common adaptation to all amniotes is the presence of an amnion in the amniotic egg.
The main function of the amnion is to provide a watery environment for the embryo to grow.

Order of Reptiles

The order of reptiles that includes crocodiles, alligators, and birds is Archosauria.

Nitrogen Excretion

In reptiles, the adaptation that leads to water-conserving nitrogen excretion is urea.

Classification

Reptiles are classified as tetrapods, meaning they have four limbs, and amniotes, meaning they lay eggs with an amnion.
The group that includes lizards, snakes, and worm-lizards is Squamata.
