Humans are, without a doubt, the most intelligent animal species. But that doesn’t mean we are the only intelligent animal out here. According to research, wild animals are far more intelligent than we give them credit for.
Intelligence in animals comes in different forms. Some animals demonstrate intelligence through the use of tools, others can solve complex puzzles, while others have a unique ability to communicate.
Although there is no comparison between human and animal intelligence, some animals are more brilliant than their counterparts.
In this article, we will have a closer look at the most intelligent marine animals.
Bottlenose Dolphins
Habitat: They are commonly found in tropical, subtropical, and temperate regions, inhabiting environments such as bays, estuaries, lagoons, and open waters.
Intelligence level: Bottlenose dolphins exhibit advanced social behavior, problem-solving skills, self-recognition, and communication through a complex system of clicks, whistles, and body movements.
Bottlenose dolphins top the list of the most intelligent marine animals. They are adorable, fun-loving, and brilliant animals.
They have larger and more complex brains than most animals, including humans. Their brain weighs about 3.5 pounds, about 0.9% of their total body weight. But size isn’t everything. They have complex clusters of neurons which are responsible for self-awareness, decision-making, and problem-solving abilities.
Besides, they also have a complex social language, using clicks and whistles to communicate. They use this language for coordinated hunting.
Dolphins also have a remarkable memory. They can remember the calls of other dolphins even up to 20 years. They can also remember the location of food sources and navigate long distances to find them.
On top of that, they are also capable of problem-solving and using tools. For example, they have been observed using sponges to protect their noses while foraging. Further, they also show compassion to others. They care for the injured, sick, and elderly within their pod. They even mourn their own dead.
Orcas
Habitat: Orcas are found all over the world’s oceans, from the polar regions to tropical waters.
Intelligence level: Orcas exhibit problem-solving skills, the ability to communicate through various vocalizations, and they also create their own social system.
Also known as killer whales, orcas have enormous brains. They have the second largest brain (almost 4 x that of a human!) of any marine mammal, after sperm whales. This feature allows them to store memories and interpret nerve signals.
Orcas also have complex social networks, forming strong family bonds and alliances with other members. In addition, they pass on knowledge from the previous generations to the younger ones.
Their intelligence is also evident in their ability to communicate through a range of vocalizations and dialects. They also exhibit problem-solving abilities and have been observed using advanced hunting techniques, such as beaching themselves to capture prey.
Sea Otters
Habitat: Sea otters are found in temperate waters, commonly inhabiting rocky shorelines and kelp forests.
Intelligence level: They are known to use tools such as rocks to crack open shellfish for food.
Sea otters have developed skills that allow them to use tools like rocks to source thier food. Recent research shows that sea otters started using tools millions of years ago.
In addition to using tools, they exhibit complex learning and problem-solving abilities. They are also known to solve puzzles and can recognize different human faces.
They also possess an impressive memory, which helps them locate their favorite hunting spots. They have also evolved into excellent swimmers, using their intelligence to navigate and survive in marine environments. For that reason, they rank as one of the most intelligent marine animals.
Octopuses
Habitat: Octopuses are most abundant in warm tropical and sub-tropical waters around the world.
Intelligence level: Octopuses have the ability to solve puzzles, open jars, and also exhibit self-awareness.
When it comes to intelligence, vertebrates generally outdo invertebrates. But octopuses are a prove that you don’t need a backbone to have a big brain. So, octopuses have a large brain and an extensive nervous system, with two-thirds of their neurons located in their eight arms.
Their intelligence is comparable to that of dogs, and their brilliant problem-solving skills have been widely documented. For instance, octopuses in captivity have been observed to use water jets to turn out lights they find annoying. They have also been observed to sneak into neighboring tanks to steal fish.
Using their intelligence, octopuses use tools to solve problems. For example, they can steal tentacles from jellyfish and use them as weapons.
Another revelation of octopuses’ intelligence is their complicated use of camouflage. They copy elaborate textures or imitate other animals to keep off predators. They are also able to recognize individual people, enjoy playing with toys, and can solve mazes too. They can also open jars.
Manta Rays
Habitat: Manta rays are pelagic and mainly inhabit tropical, subtropical, and temperate waters around the world.
Intelligence level: They have remarkable learning abilities and impressive memory. They also display emotional intelligence and form unique individual relationships with each other.
Manta rays are remarkably one most intelligent marine animals. While they may not possess the same level of cognitive abilities as dolphins and whales, mantas still display remarkable behaviors and problem-solving skills.
According to research, they have an exceptional capacity for learning and a great memory, as they can remember specific feeding areas. Additionally, mantas show a sophisticated social system. They are able to recognize and interact with each other.
Their intelligence is further demonstrated by their ability to communicate through body language and collaborate during hunting. These animals also get inquisitive around people. They will even associate and play with them. A new study shows that giant manta rays can recognize their reflection.
Sea Lion
Habitat: Sea lions live in shallow temperate and subpolar waters in all the world’s oceans, with the exception of the Northern Atlantic Ocean.
Intelligence level: They possess remarkable skills for social learning, problem-solving abilities, effective communication, and an impressive memory.
Sea lions are highly intelligent animals. They show great ability for social learning. They are able to learn from each other’s behavior and communicate effectively using barks and growls. They use these vocalizations to identify themselves, organize group hunting, and take care of their young ones.
They also possess problem-solving skills, the ability to recognize themselves in mirrors, and even use tools to solve problems. Besides, they are also trained to perform certain tasks and are often used in areas such as military and rescue operations.
According to research, their brain-to-body ratio is comparable to that of dolphins, which are one of the most intelligent marine animals.
Penguins
Habitat: Penguins primarily live in the Southern Hemisphere, with the exception of the Galapagos Penguin.
Intelligence level: They are incredibly good at creating mental maps, are able to recognize each other’s calls, and hunt as a team.
Adding to our list of the most intelligent marine animals are penguins. Although they are not as intelligent as bottlenose dolphins, they are smart in their own way. One fascinating aspect of their intelligence is their ability to create mental maps.
Even after being away for extended periods, penguins are still able to find their way back to their colonies. This is because of their great memory and their ability to use visual cues such as hills and rivers.
Another aspect that makes penguins intelligent is their ability to hunt in groups and work together as a team to increase their chances of catching prey. Also, despite their nearly identical looks, they are able to recognize their mates and offspring in a colony of hundreds.
Further, they use a range of vocalizations, such as loud noises and barking, to communicate and identify one another. They also possess problem-solving abilities as they know how to get around obstacles in their surroundings.
Great White Sharks
Habitat: Great white sharks are mainly found in temperate coastal waters all over the world.
Intelligence level: When hunting, they work together as a group and make calculated attacks.
The great white sharks are apex predators and one of the most feared animals in the ocean. But how intelligent are they? Recent research has shown that great white sharks are undeniably one of the most intelligent marine animals.
Their prey includes seals and dolphins, which are highly intelligent animals. The sharks, therefore, must have enough brains to hunt them down.
They are extraordinarily clever, with cognitive abilities comparable to those of primates. They are also fast learners with impressive memory and can remember answers to puzzles for up to a year.
At the same time, they exhibit social learning, whereby they learn by observing their peers. And despite their reputation as lone hunters, they in some cases, team up to hunt in groups and then share the spoils.
