Crocodile Station does a Cumbarjua crocodile spotting cruise. This Canal is the link that connects the Zuari and the Mandovi rivers. This 15 km long canal is the best place for crocodile spotting in Goa. There is an interesting legend attached to the canal and the crocodiles that have given the crocodiles the name "muggers". It is believed that about a 100 years ago, some of these crocodiles were floated in the waters to keep away enemies.
The one unique feature that separates these "muggers" from other crocodiles is that they have successfully adapted and prospered in saline water, whereas crocodiles are freshwater creatures. The mangrove forests are also home to various fishes and mollusks. You will also get glimpses of the colorful bird life that is present here.
