deep trouble

one of the special features of the blue planet series dvd is called "deep trouble", in which they tried to draw people's attention to the human impact to the fish, or, life in the ocean. polution of course is fatal, but equally devastating is fishing.

blue planet

this is a series produced by bbc, describing the beauty and marvel worlds of the seas.

both of the two of the most astonishing scenes are related to killer whales. in the first one, a group of killer whales attacked the migrating grey whales, just off shore california. a mother grey whale traveled with her calf, which was the target of the killers. they chased the greys for five hours, until the calf was totally exhausted, then drowned and torn apart the calf.

in the second, killer whales attacked seal calfs while they were learning to swim. in one particular case, a calf was caught, but was not eaten right away. instead, the killers tossed it high above the ocean surface like playing volley ball. cruel creatures.
