In the present study autotomy was induced in pholcid and lynx spiders. We recorded self amputation in only 13.45% house spiders compared to 42.5% in lynx spiders. Highest self-amputation rate in house spiders was observed in leg II (21%). However, lynx spiders showed 60% self-amputation in leg II. Almost 89% house spiders removed their legs when stretched from femur. However, lynx spiders (90%) automize their leg when stretched from metatarsus. For both group of spiders self amputation was higher in adult and between coxa and trochanter. It is confirmed from the study that self amputation is an important phenomenon in spiders to protect themselves in life-threatening situations.

Abstract
In the present study autotomy was induced in pholcid and lynx spiders. We recorded self amputation in only 13.45% house spiders compared to 42.5% in lynx spiders. Highest self-amputation rate in house spiders was observed in leg II (21%). However, lynx spiders showed 60% self-amputation in leg II. Almost 89% house spiders removed their legs when stretched from femur. However, lynx spiders (90%) automize their leg when stretched from metatarsus. For both group of spiders self amputation was higher in adult and between coxa and trochanter. It is confirmed from the study that self amputation is an important phenomenon in spiders to protect themselves in life-threatening situations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
