The snake was swimming when suddenly a 'black shadow' ambushed from below, will it escape death?

A grass snake (two-part nomenclature: Natrix natrix) of the Water Snake family was swimming underwater when it was suddenly ambushed from the water. It turned out that the snake had accidentally entered the domain of diving birds (Scientific name: Podicipedidae ).

The snake had accidentally entered the diving bird's territory.

The mother bird sensed danger and attacked the grass snake to protect her cubs. Being a very good diving bird, diving birds always attack enemies from under the water. The snake was hit in the back of the head but was not seriously injured.

Grass snakes usually live near water sources and eat almost exclusively amphibians. They are not venomous, so they kill their prey by entanglement. To defend themselves, this snake will secrete a garlic-smelling liquid (from a gland in the anus), fake death or make a hissing sound to scare.
