In these situations, "the juvenile did not catch the flung prey, but held on to the sea lion it had caught itself " (p. 182).
I agree that the sea lion is a mammal of different dimensions from the dolphin, for example.
I come back to the fact that the dolphin is different from the sea lion.
Surely if a trainer is said to be cruel to a dog, a cat or a chimpanzee, he will also be cruel to a sea lion or a horse.
And what about the high degree of skill of the sea lion?
When moving on land, the sea lion is able to turn its hindflippers forward and walk on all fours.
The central feature of the original zoo, ranged round the sea lion pool, was retained and the pool redesigned.
It features an underwater viewing window and is over three times as deep as the old sea lion pool, built in the 1930s.
