Exercise 73: True, False, Not Given 
Read the following text and answer true, false or not given. 
The killer whale, commonly referred to as the orca, and less commonly as the 
blackfish, is a toothed whale belonging to the oceanic dolphin family. Killer 
whales are found in all oceans, from the frigid Arctic and Antarctic regions to 
tropical seas. As a species they have a diverse diet, although individual 
populations often specialize in particular types of prey. Some feed exclusively on 
fish, while others hunt marine mammals such as sea lions, seals, walruses and 
even large whales. Killer whales are regarded as apex predators, lacking natural 
predators and preying on even large sharks. 
Killer whales are highly social; some populations are composed of family groups 
which are the most stable of any animal species. Their sophisticated hunting 
techniques and vocal behaviors, which are often specific to a particular group 
and passed across generations, have been described as manifestations of 
culture. 
Questions: 
1. 
Killer whales are predominantly found in cold water areas.
2. 
Some killer whale groups only eat fish.
3. 
They may even eat large sharks.
4. 
Killer whales are able to pass on skills to their young.
