Records of Dhofar toads duttaphrynus dhufarensis from Al Ain, Abu Dhabi Emirate, United Arab Emirates.

Introduction

Two amphibian species are recorded in the United Arab Emirates, UAE, the Dhofar toad Duttaphrynus dhufarensis and the Arabian toad Duttaphrynus arabicus. Dhofar toads can usually be found further away from permanent water sources whilst Arabian toads are usually restricted to areas near water. The distribution of both species in the UAE is mainly confined to the wadis of the Northern Emirates. The known distribution of the Dhofar toad in the UAE and Oman is shown in Fig. 1.

Dhofar toads in Wadi Al Ain

Dr. Arshad Toosy, Manager Veterinary Operations, Al Ain Zoo, had reported that he had seen a toad during 2010 and had heard toads calling in Wadi Al Ain, which runs through the Zakher area of Al Ain city. A daytime survey was done in the Wadi Al Ain on 14 February 2011 and no presence of toads was recorded. On 3rd April 2011 at 19:30 hrs a gravid female was recorded next to Wadi Al Ain at N24.201941[degrees], E 055.726632[degrees] by Arshad Toosy as shown in Fig. 1. The wadi was again searched on 4 April during the morning hours and no further presence of toads was recorded. On 16 April 2011 at 22:15 hrs the wadi was checked again.

On arrival, toads could be heard croaking in the wadi from a distance of at least 150 m. Upon inspection, at least four Dhofar toads were recorded in an area centred on the following location N24.202052[degrees], E055.723477[degrees]. This area was searched again on 17 April 2011 at 22:00 hrs. No toads were heard calling and no tadpoles or egg masses were observed in the water. Water had been observed flowing in this wadi since February 2011., this appearing to be the run-off from nearby irrigation. There were also Tilapia fish present in the water, these being visible along the length of this wadi.
