The safari park in Cox's Bazar has failed in breeding of the sweet-water crocodiles gifted by the Indian authorities more than two years back. The Indian government gave 40 sweeter-water crocodiles as a gift to Bangladesh from its reptile bank in Chennai at the end of 2005, official sources said. Twenty-nine of them were released in the lake of the country's lone safari park near the Cox's Bazar tourist resort for their breeding while five were sent to Dhaka Zoo and the remaining released in Khan Zahan Ali mazar pond in Bagerhat. As sweet-water crocodiles have become extinct in Bangladesh long ago, the government sought the gift consignment of these species for their breeding and growth, the officials said.
