## First Understanding: Description of Terrestrial Animals
**Quadrupedal Terrestrial Animals:** There are four types of quadrupedal terrestrial animals, namely: single-hooved, double-hooved, ghandipad (elephant-like) and sankahapad (with claws). All other similar quadrupedal terrestrial animals are also included in this category. They are broadly classified into two types: sufficient and insufficient. Their body size ranges from an infinitesimal fraction of an angul (finger width) to a maximum of 9 yojan (a yojan is approximately 8 miles). Their lifespan ranges from a moment to a maximum of 84,000 years. The lifespan of other aquatic animals should be understood in a similar manner. These animals are capable of moving in four directions and returning in two directions, and they are both individual and innumerable. This concludes the description of quadrupedal terrestrial animals, which are five-sensed, non-human beings.
**Reptile Terrestrial Animals:** What are reptile terrestrial animals? There are two types of reptile terrestrial animals: snake reptiles and lizard reptiles. What are snake reptiles? There are four types of snake reptiles: ahi (cobra), ajagar (python), asaliya (non-venomous snake) and mahorag (large snake). What are ahi? There are two types of ahi: darvikar (hooded) and mukuli (non-hooded). What are darvikar? There are many types of darvikar, such as pashvisha (venomous) and others. This concludes the description of darvikar. What are mukuli? There are many types of mukuli, such as divy (divine) and gonas (non-divine). This concludes the description of mukuli. What are ajagar? There is only one type of ajagar. This concludes the description of ajagar. What are asaliya? The description of asaliya should be understood according to the Prajnapanasutra. What are mahorag? The description of mahorag should be understood according to the Prajnapanasutra. All other similar snake reptiles are broadly classified into two types: sufficient and insufficient. The rest should be understood as before. Specifically, their body size ranges from an infinitesimal fraction of an angul to a maximum of 9 yojan. Their lifespan ranges from a moment to a maximum of 75,000 years. The rest should be understood in a similar manner as aquatic animals. These creatures are capable of moving in four directions and returning in two directions, and they are both individual and innumerable. This concludes the description of snake reptiles.
**Lizard Reptiles:** What are lizard reptiles? There are many types of lizard reptiles, such as goh (gecko) and nevala (mongoose). All other similar lizard reptiles are also included in this category. They are broadly classified into two types: sufficient and insufficient. Their body size ranges from an infinitesimal fraction of an angul to a maximum of 9 dhanush (dhanush is a unit of length, approximately 4 feet).
