চুক ভেকুলী (ইংৰাজী: Asian common toad, বৈজ্ঞানিক নাম-Duttaphrynus melanostictus দক্ষিণ-পূব এছিয়াত বহুলভাৱে বিস্তৃত হৈ থকা এবিধ ভেকুলীৰ প্ৰজাতি৷[1]এই ভেকুলী প্ৰায় ২০ ছে:মি: পৰ্যন্ত ডাঙৰ হ'ব পাৰে৷ ই সাধাৰণতে বাৰিষা প্ৰজনন কৰে৷

A male in breeding colours. It turns yellowish green during the monsoon. Note the black lines behind the eye.

বিৱৰণ[সম্পাদনা কৰক]

The wart patterns of the toads are unique and have been used for individual identification in studies.

The top of the head has several bony ridges, along the edge of the snout (canthal ridge), in front of the eye (pre-orbital), above the eye (supra-orbital), behind the eye (post-orbital), and a short one between the eye and ear (orbito-tympanic); The dorsal side is covered with spiny warts. The parotoids are prominent, kidney-shaped or elliptical and elongated. The dorsal side is yellowish or brownish and the spines and ridges are black. The underside is unmarked or spotted.[2]

বিতৰণ[সম্পাদনা কৰক]

Asian common toads occur widely from northern Pakistan through Nepal, Bangladesh, India including the Andaman and Nicobar Islands, Sri Lanka, Myanmar, Thailand, Laos, Vietnam, Cambodia and southern China, Taiwan, Hong Kong and Macau to Malaysia, Singapore, and the Indonesian islands of Sumatra, Java, Borneo. They were introduced to the islands of Bali, Sulawesi, [[Ambon Island in New Guinea.

বাসস্থান[সম্পাদনা কৰক]

They have been recorded from sea level up to 1,800 মিটাৰ (5 ফুট) altitude, and live mostly in disturbed lowland habitats, from upper beaches and riverbanks to human-dominated agricultural and urban areas. They are uncommon in closed forests.[1]

আচৰণ[সম্পাদনা কৰক]

খাদ্য[সম্পাদনা কৰক]

They are often seen at night under street lamps especially in times when winged termites swarm. They have been noted to feed on a wide range of invertebrates including scorpions.[3] Tadpoles grown in sibling groups metamorphosed faster than those that were kept in mixed groups.[4]

প্ৰজনন[সম্পাদনা কৰক]

Asian common toads breed in still and slow-flowing rivers and temporary and permanent ponds and pools. Adults are terrestrial and may be found under ground cover such as rocks, leaf-litter, logs, and are also associated with human habitations. The larvae are found in still and slow-moving waterbodies.[1][5]
