Answer:
$16 million (provided that it is in US dollar) is equivalent to 16 orca/killer whales (each costs $1 million)
Step-by-step explanation:
I'm not sure what equivalent you're looking for, but $16 million is worth a lot of money. You can actually purchase 16 killer whales with that. An orca whale is the largest member of the dolphin family and most of them can be purchased from Russia.
You may also use the money for a sharing program, such as the 16-million-dollar bike sharing program in Los Angeles. It would be a great advancement in the people's mobility. This will give more liberty to public spaces.
