# छुँ (रोदेन्त)

**छुँ बाय् रोडेन्ट** (Rodent) धयागु 'रोडेन्सिया' (Rodentia) पुचलय् लाःगु दुरुप्वः दुपिं प्राणीतयगु छगू तःधंगु पुचः खः। हलिंया फुक्कं दुरुपादुपिं प्राणीत मध्ये करिब ४०% प्रजातित रोडेन्ट पुचलय् ला। थ्व पुचलय् साधारण छुँ (Mice), तिछुँ (Rats), सिमाछुँ (Squirrels), चुसा (Porcupines), व बीभर (Beavers) थेंज्याःगु प्राणीत ला। थ्व प्राणीतयगु दकलय् मू विशेषता धयागु इमिगु निरन्तर बुयाच्वनिगु इन्सिजर 'वा' (Teeth) खः।

## म्हया दयेका

रोडेन्टतयगु म्हया दयेकाय् छुं विशिष्ट खँत दइ:

* **निरन्तर बुयाच्वनिगु वा (Incisors):** रोडेन्टतयगु म्हुतुया न्ह्यःनेया च्वय्या व क्वय्या प्यपू वा (Incisors) जीवनभर बुयाच्वनि। उकिं इमिं न्ह्याबलें छुं न छुं वस्तु न्यानाच्वनेमाः (gnawing), गुकिं यानाः इमिगु वा तसकं ताःहाकः जुइ मखु।
* **इनामेल (Enamel):** इमिगु वाया न्ह्यःनेया भागय् तसकं क्वातुगु इनामेल दइ धाःसा ल्यूनेया भाग भचा नाइसे च्वनि। थुकिं यानाः वस्तु न्याइबलय् वा थःहे ज्वया (sharp) वइ।
* **चिधंगु म्ह:** अप्वः थें रोडेन्टत म्हया आकारय् चिधं जुइ, तर 'क्यापिबारा' (Capybara) थेंज्याःगु रोडेन्ट तसकं तःधं नं जुइ।
