In Jainism, "Charmavarti Jiv" (Sanskrit: चर्मावरण जीव) refers to organisms that have four senses (chaturindriya jiva) and specifically those covered by a skin (charmavritta). The term "lakshan" means characteristics or features.

Charmavarti Jiv Lakshan:

• These are four-sensed beings (have the sense of touch, taste, smell, and sight).
• They are distinguished by the presence of skin covering their body.
• Examples include scorpions and crabs.
• They are more developed than two- or three-sensed beings, but less than five-sensed beings.
• Jain scriptures categorize them under the broader classification of "chaturindriya jiva" (four-sensed beings).
• According to Jain philosophy, these beings are capable of experiencing pleasure and pain to a greater degree than lower organisms.

Summary Table:

| Category | Senses Present | Example Organisms | |------------------------|----------------------------|------------------------| | Charmavarti Jiv | Touch, Taste, Smell, Sight | Scorpions, Crabs |

In Jain cosmology, understanding such classifications helps in observing Ahimsa (non-violence) more accurately.
