Abstract

Tail autotomy is a common and highly effective defensive mechanism observed in many lizard species, allowing individuals to escape predators by shedding a portion of their tail. This behavior, while beneficial for survival, can sometimes result in typical outcomes during tail regeneration. One such rare disorder is tail bifurcation often due to incomplete or misdirected regenerative processes. On June 23, 2025, during fieldwork in the rural areas of Afyonkarahisar Province, a female snake-eyed lizard (Ophisops elegans), belonging to the Lacertidae family, was observed with a clearly bifurcated tail. The specimen was captured and examined briefly, and morphometric, biotic, and environmental data were recorded. Photographs were taken to document the anomaly, and the specimen was subsequently released in its habitat. This field observation contributes to the growing number of bifurcated tail reports in Lacertidae and emphasizes the value of in situ herpetological monitoring. Observations in this study enhance our understanding of caudal autotomy and tail regeneration and also provide insights into developmental biology, wound healing, and ecological implications of tail malformations in natural populations.

Batı Anadolu’dan Ophisops elegans’ta Nadir Bir Kuyruk Çatallanması Vakası

Abstract

Kuyruk ototomisi, birçok kertenkele türünde gözlemlenen yaygın ve son derece etkili bir savunma mekanizmasıdır. Bu mekanizma, bireylerin kuyruklarının bir kısmını bırakmaları sayesinde yırtıcılardan kaçmalarına olanak tanır. Hayatta kalma açısından faydalı olsa da bu davranış, bazen kuyruk yenilenmesi sürecinde alışılmadık sonuçlara yol açabilir. Bu nadir düzensizliklerden biri, eksik ya da yanlış yönlenmiş yenilenme süreçleri sonucunda ortaya çıkan kuyruk çatallanmasıdır. 23 Haziran 2025’te, Afyonkarahisar ilinin kırsal bölgelerinde gerçekleştirilen arazi çalışmaları sırasında, Lacertidae familyasına ait dişi bir tarla kertenkelesi (Ophisops elegans) bireyinde belirgin şekilde çatallı bir kuyruk gözlemlenmiştir. Örnek kısa süreliğine yakalanarak incelenmiş; morfometrik, biyotik ve çevresel veriler kaydedilmiştir. Anomaliyi belgelemek amacıyla çeşitli fotoğraflar çekilmiş ve birey, yakalandığı habitatta tekrar doğaya salıverilmiştir. Bu arazi gözlemi, Lacertidae familyasında çatallı kuyrukla ilgili sınırlı fakat artan sayıdaki raporlara katkı sağlamakta ve yerinde (in situ) herpetolojik gözlemlerin önemini vurgulamaktadır. Bu tür gözlemler, yalnızca kuyruk ototomisi ve kuyruk yenilenmesi hakkındaki bilgilerimizi geliştirmekle kalmaz, aynı zamanda doğal popülasyonlarda kuyruk malformasyonlarının gelişim biyolojisi, yara iyileşmesi ve ekolojik etkileri konusunda da önemli içgörüler sunar.
