Oceans: An Evolution Game Is Now Open For Outside Playtesting

They have been known to catch anything in the water, including blue whales, great white sharks, and even boats.
Orcas can swim up to 30 miles per hour and their teeth are sharp enough to tear apart their prey, but their most dangerous weapon is their brain.

An orca’s brain is five times larger than a human’s, but has the same structure as ours.
For example, orcas have a well-developed insular system that gives them self-awareness, social understanding and empathy. These advanced skills are useful in their hunting activities.
“Additionally, marine animals like whales and dolphins have a special part of the brain called the paralimbic system,” said Lori Marino, neuroscientist and founder and president of The Whale Sanctuary Project.
In fact, the paralimbic system of the orca brain is more complex and sophisticated than that of the human brain.

The effect is unclear, but based on their knowledge of other parts of the brain, scientists believe this complex paralimbic system helps integrate information from parts of the orca’s brain that control emotions and those that control higher-level thinking.
Orca social groups, or boats, can range from five to 30 orcas, but boats tend to join larger target groups, such as in 2021 when 80 orcas were killed by a 59-foot-long blue whale.
Footage of the incident shows how the orcas chased the whales, then groups of 6-8 took turns killing the whales and circling their holes to stop them breathing. The hunt lasted over three hours.
Additionally, their abundance helped prevent competing predators such as pilot whales and hammerhead sharks from stealing food.

A floating seal will provide protection on the ice, but it won’t be safe for long. The orcas create slow waves to break the reef and the seal slides right into the mouth of the sieve.
It’s even more interesting because bats pass on not only their hunting methods, but also their telltale clicks and whistles to future generations.
Orcas: Apex Predators Or Marine Park Stars?
Orcas are one of the few non-human animals to have developed this level of cultural sophistication, according to the Orca Network.
But that doesn’t mean orcas are human when they die. Their differences are what make them some of the largest predators in the sea, especially their brain’s ability to receive and process sound.
Sound travels four times faster in water than in air, and orcas can take advantage of this to scan their surroundings like a radar by emitting hums, clicks and whistles. — This power is called echolocation.
“Orca is very good at determining the direction of sound,” Marino said. They use echolocation not only to communicate with each other and detect obstacles, but also to hunt for food and control specific prey organs.

For example, orcas can use echolocation to locate fish up to 500 feet away, determine the size of the fish, and move on to larger meals, such as older Chinook salmon.
Echolocation helps explain how killer whales off the coast of South Africa, apparently relishing the taste of fatty, high-calorie shark livers, rip open the liver with their first bite. They need to know where the liver is and maybe an echo can help explain the cause.
Marino says that figuring out the origin and nature of each sound he hears may require “very complex neurobiological stimulation.” Scientists believe orcas are able to make these calculations because their brains vibrate.
The brain structure of most mammals is the same: there are folds outside the gray matter where all the nerve endings send messages to each other. Beneath the surface is white matter that acts like a cord that connects nerve endings to different parts of the brain.

In general, the larger the animal’s brain, the more horizontal the white matter is and connects all the extremities. But marine fish, including killer whales, don’t follow this rule.
Orcas have the most wrinkled brains of any animal, including humans. The tissue on the surface of their brain has nerve endings closer together, so it takes less time and energy to send messages back and forth.
This fast neural transmission allows them to register, process and respond to sounds faster than other marine animals. In other words, they think fast and are quick on their feet – yes, in this particular case, with fins. Great white sharks are known as one of the most fearsome predators in the ocean, but recent research shows that great whites are just plain scary. killer whale!
Not So Solitary Predators? Great White Shark Duo Appear To Be Travelling Together
In 2009, Salvador Jorgensen and his colleagues identified 17 great whites off the coast of California at the Monterey Bay Aquarium. Great white sharks often eat elephant seals. When the sound went out into the surrounding waters, the sharks disappeared and within 8 hours they were all gone. Most of them did not return for the rest of the elephant seal season (September to December). If orcas stopped roaming and hunting, the number of seals hunted would decrease by about 62%, and the young seal population would be more likely to survive the season.
The researchers looked at data from 165 whites tagged between 2006 and 2013, which is unusual. They discovered a plan – when the orcas entered the area, all the sharks fled. Some come back after a few months, some don’t come back for 1 year, even after wandering around the area. Sharks are believed to smell approaching orcas, even if they are not close enough to see them.
Why are great white sharks afraid of orcas? The relationship between the two does not end well for the shark. In 1997, the first communication between great whites and orcas was recorded. A great white shark kills two orcas and eats their liver. It is common for killer whales to remove the liver and leave the rest of the body. In 2017, 5 great whites washed up in South Africa with similar symptoms. The liver was taken in meticulous detail and the culprit is believed to be an orca.
Orcas are very intelligent and work in groups when hunting. Although their existence is short, they have a significant impact on the surrounding ecosystem. When white sharks escape, they do not hunt in the area for a year, their prey does not decrease and they affect other parts of the ecosystem. It’s always exciting and fun to learn more about the oceans and the people who live there. It seems safe to say that the biggest predator in the ocean right now is the orca whale! Megalodon ate all of today’s killer whales and was able to wander the sea without food for two months.

Megalodon, the largest shark that ever lived, was famous for its teeth as big as a human hand. However, there are few fossils showing its entire body. Using the well-preserved specimen, international and UZH researchers created a 3D computer model of his entire body. They found that Megalodon could have eaten an entire meal the size of a modern killer whale and wandered the ocean for up to two months without food.
) is 16 meters long and weighs more than 61 tons. It is believed to swim at a speed of 1.4 meters per second, capable of displacing over 98,000 kilograms per day and having a stomach volume of around 10,000 litres. These results show that Megalodon can travel far and eat up to 8 people.
