Yellow anaconda

Eunectes notaeus

The yellow anaconda is smaller than the better known green anaconda (Eunectes murinus); it typically reaches lengths of between 2.5m and 4m and weights up to 40kg, with females being larger than males.

It is an ambush hunter and a constrictor. It hides in the water and among vegetation to attack passing prey. When it catches its prey, it begins to wrap its body around it and begins to contract, then swallows the prey’s head first by unhinging its jaws.

It is distributed in eastern Bolivia, Paraguay, western Brazil, northeastern Argentina.

Anacondas do not lay eggs; instead, they give birth to offsprings. The offsrpings are attached to a yolk sac and surrounded by a transparent membrane, not a shell, as they develop in their mother’s body.
