Tokelau $5 Dollar Silver Proof Coin, 2012, UNC, Marine Life ,Orca, Killer Whale
Orcas are true monsters of the oceans. They grow to be between 7 and 9 meters long and can weigh up to 6 tons. Although it prefers cooler waters and therefore is not often found in tropical waters, this colossus is found in all oceans of the world.
Killer Whales are carnivorous animals and require an energy intake of approximately 290‘000 Kcal per day. In comparison humans need an average of about 2‘700 Kcal.
The mammals owe their unflattering second name “Killer Whale„ which refers to their seemingly brutal hunting methods resembling those from whalers. Whether the whalers themselves proceed more gently is anyone’s guess.
Nevertheless, Orcas are far from aggressive; but rather show a marked social behaviour with a clearly structured hierarchy. Several forms of dialect in their communication have been noticed within the individual families.
