Orca's eye are located in the left-most corner of the eye patch. The white patch serves as camoflage, but also the females can choose the males with the biggest eye patch.
Why do orcas have fake eyes?
They are dwarfed by the huge eyespot or false eye above and behind the real eyes. Eyespots also called eye patches, may have evolved to help whales identify each other, or to protect their real eyes from the attacks of sharks. The size and shape of eyespots differ depending on what type of orca it is.21-Sept-2021

Why are orcas eyes red?
It's why we call it the 'red eye' because all around their blue iris, these blood vessels look like they've burst because they are so stressed. The whale whose death I was present for, actually ended up trapped in a net.09-Mar-2016
Are orcas friendly to humans?
Many young orca or adults with young will approach and play with and alongside humans too. Generally speaking yes and in the wild almost always. They might be aloof and not particularly keen to let humans near or bother them in the wild but if and when they've had enough, the worst they'll do is swim away.
How intelligent are orca whales?
Orcas' brains are 2 1/2 times average — similar to those of chimpanzees. But scientist think that looking just at the brain-body ratio seriously underestimates the thinking power of larger marine mammals. In other words, orcas might be even much smarter than the size of their big brain suggests.06-Mar-2010

What colors can orcas see?
“Whales only have one cone, which is sensitive to green light, so they see in black and white in light and dark,” Fasick said. They have one cone and one rod, both of which are sensitive to light in the blue/green range of the color spectrum. “They match their cones and rods to the color of the water.22-Nov-2011
Do orcas have good vision?
Orcas have excellent eyesight in and out of the water. They also have a well-developed sense of hearing. And like other cetaceans, Orcas receive sound through receptors in their jawbones. The jawbone acts like a conduit, transmitting the sounds to the ear canal and auditory nerves.10-Aug-2011

Why can't orcas kill great whites?
Because they can’t. Orcas kill great whites (and other smaller sharks) by flipping them upside down, which causes what’s called Tonic Immobility. In that state, the shark is sort of paralized, and unable to move until it’s flipped back to its normal position. Tonic Immobility, by itself, doesn’t kill.
What happens if a shark attacks an orca?
If a shark attempted to attack an orca, the rest of the group would retaliate. To make matters worse for the shark, orcas coordinate their attacks when hunting in a group. 2) Orcas have a too thick layer of fat, which makes it hard, if not impossible, for even a great white to inflict a fatal wound.
What is the white patch on an orca's eye?
The white patch serves as camoflage, but also the females can choose the males with the biggest eye patch. Interesting, when I first saw a n Orca close up I was amazed how small the eye appeared in comparison to the animal’s size. To answer your question, you will find the Orca’s eyes on either side of his/her head.
Do orcas have a society?
Orca have a society and standards within that society. You are dealing with highly intelligent non human animals who have language and families and are self aware. Only if you can understand all these things, should you swim with Orca. Over many years, I have followed and come to know many Orca and their families.
Do orcas eat seals?
The Orca have decided to work with you and therefore won't hurt you. Like the seal they used to teach a pod to dump seal off an ice flow. They put the seal back each time they dumped him, and they didn't eat him. Orca have a society and standards within that society.
Where are the eyes of a killer whale?
A killer whale's eyes are on each side of its head, just behind and above the corner of its mouth, and in front of its white eyespot. A killer whale's eyes are about the same size as the eyes of a cow. The dorsal (top) part of its body is black, with a pale white to gray "saddle" behind the dorsal fin.
Who runs the pods in the dolphins?
Their PODS are run by a senior female. Your dive team would need a female leader who knew dolphin language. She would have to be aware of the messages sent to her by the pod. Usually by a juvenile Orca who has been assigned to the humans.
What color is the orca?
The Orca is counter shaded: black on the top and mostly white on the bottom. Looking down from above, the black on the dorsal side mixes with the dark ocean. Looking up from below, the white on the ventral side blends into the sunlit water. Other animals may not recognize a Killer whale until it’s too late.
What is the dorsal fin of an orca?
On females it’s a bit shorter and more curved. The dorsal fin acts like a keel, and each dorsal fin is unique for each Orca. The peduncle is the large muscular area between the dorsal fin and the flukes. The caudal peduncle is the part where the flukes meet the body.
What part of the body is where the flukes meet?
The caudal peduncle is the part where the flukes meet the body. There aren’t any bones or cartilage in the dorsal fin and flukes. Instead, they’re made up of dense connective tissue. Longitudinal muscles in the back and caudal peduncle move the flukes up and down. The Orca’s pectoral fins are paddle-shaped.
What is the name of the whale that is a killer whale?
Orcinis Orca. They’re commonly known as the Killer whale. But the Orca isn’t actually a whale: it’s in the dolphin family.#N#And while it shares a lot of the same characteristics of dolphins, the Orca has some unique features that are all its own, like its camouflage coloring. The Orca is counter shaded: black on the top and mostly white on the bottom. Looking down from above, the black on the dorsal side mixes with the dark ocean. Looking up from below, the white on the ventral side blends into the sunlit water. Other animals may not recognize a Killer whale until it’s too late.#N#Male Orcas have the largest dorsal fin of any marine mammal. It can get up to 6 feet tall. On females it’s a bit shorter and more curved. The dorsal fin acts like a keel, and each dorsal fin is unique for each Orca. The peduncle is the large muscular area between the dorsal fin and the flukes. The caudal peduncle is the part where the flukes meet the body. There aren’t any bones or cartilage in the dorsal fin and flukes. Instead, they’re made up of dense connective tissue. Longitudinal muscles in the back and caudal peduncle move the flukes up and down. The Orca’s pectoral fins are paddle-shaped. They’re used for steering and work in conjunction with the fluke for stopping. Inside these appendages is a network of veins that help regulate body temperature.#N#In between the dorsal fin and the peduncle is a grey swoosh known as the saddle patch. There are two types of saddle patches: open, which has more black in it: and closed, which has more white. The coloring varies depending on where the Orca lives. The eye is located just below and in front of the eyespot. Orcas have excellent eyesight in and out of the water. They also have a well-developed sense of hearing. And like other cetaceans, Orcas receive sound through receptors in their jawbones. The jawbone acts like a conduit, transmitting the sounds to the ear canal and auditory nerves.#N#Orcas also use echolocation. They create high frequency sound waves that are passed through the melon. The melon focuses these sounds and projects them into the water. The sound bounces off the objects and returns in the form of an echo. Just beneath the melon is the rostrum, and inside the rostrum are the Orca’s teeth. Orcas have anywhere form 40 to 56 interlocking teeth – each one around three inches long. They’re conical shaped and used for ripping and tearing, but not for chewing. Orcas eat their food in chunks or entirely whole.#N#Cetaceans are conscious breathers. They have to remember to take a breath every time they need air. Orcas breathe by opening the muscular flap of the blowhole. When closed, the blowhole is completely airtight. All of these parts working together make the Orca one ominous, awesome marine mammal.
How much does a killer whale eat?

How to tell if a killer whale is male or female?
An individual killer whale can often be identified from its dorsal fin and saddle patch. Variations such as nicks, scratches, and tears on the dorsal fin and the pattern of white or grey in the saddle patch are unique.
What do killer whales eat?
Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack baleen whale calves, and even adult whales.
How big are killer whales?
Females are smaller, generally ranging from 5 to 7 m (16 to 23 ft) and weighing about 3 to 4 tonnes (3.0 to 3.9 long tons; 3.3 to 4.4 short tons). Calves at birth weigh about 180 kg (400 lb) and are about 2.4 m (7.9 ft) long. The skeleton of the killer whale is of the typical delphinid structure, but more robust.

What do orcas eat?
Looking at all populations, orcas are generalist eaters, consuming fish, seals and sea lions, dolphins and porpoises, sharks and rays, large whales, cephalopods (octopods and squids), seabirds and more. However, some orcas specialise on specific prey, and it turns out orcas are picky eaters!
Why are orcas called killer whales?
Orcas were given the name ‘killer whale’ by ancient sailors’ observations of groups of orcas hunting and preying on larger whale species. They called orcas asesina ballenas, or ‘whale killer’ – a term that was eventually flipped around to the easier ‘killer whale’. Their Latin name, Orcinus orca, also reflects this observation ...

Do orcas sleep in a deep sleep?
If like us, orcas went into a deep unconscious sleep, they would stop breathing and suffocate or drown. To get around this, orcas only allow one half of their brains to sleep at a time; the other half stays alert enabling them to continue breathing whilst looking out for dangers in the environment.
Is an orca a killer whale?
Orcinus translates to ‘of the kingdom of the dead,’ and orca refers to a kind of whale. We know that orcas are top predators, yes, but not the vicious ‘whale killers’ that the ancient mariners thought them to be.
How do orcas see?
Even though orcas can see above and below water, it is their hearing and echolocation abilities that help them locate objects in the water. By emitting clicks and listening for echoes, orcas are able to determine the size, distance, shape, and direction of underwater sea life and objects.
What do orcas call?
Orcas use “calls” to communicate with one another. Within resident pods, these calls form a dialect, which is unique to the pod and gets passed down from generation to generation.
How do orcas get toxic?
Orcas also suffer from toxic chemical contamination. Chemicals like PCB and DDT, which get dumped into the ocean via mining operations, offshore oil development, and agriculture, enter the food chain through zooplankton. As they move up the chain from invertebrate to fish to orca, these pollutants become concentrated.
Why are orcas so contaminated?
Recent studies have found that orcas are among the most contaminated marine mammals in the world, making them more susceptible to disease and likely causing reproductive difficulties.
How many generations does an orca have?
A single pod often has multiple families living together, with each family spanning as many as four generations. Transient pods are smaller and usually comprised of one adult female and one or two of her offspring. There is no distinct breeding season for orcas, but it is most common in summer.

Overview
The orca or killer whale (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.
Orcas have a diverse diet, although individual populations often specialize in particular types of …
Naming
Orcas are commonly referred to as "killer whales", despite being a type of dolphin. Since the 1960s, the use of "orca" instead of "killer whale" has steadily grown in common use.
The genus name Orcinus means "of the kingdom of the dead", or "belonging to Orcus". Ancient Romans originally used orca (pl. orcae) for these animals, possibly borrowing Ancient Greek ὄρυξ (óryx), which referred (among other things) to a whale species. As part of the family Delphinidae, …
Taxonomy and evolution
Orcinus orca is the only recognized extant species in the genus Orcinus, and one of many animal species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Konrad Gessner wrote the first scientific description of an orca in his Piscium & aquatilium animantium natura of 1558, part of the larger Historia animalium, based on examination of a dead stranded animal in the Bay of Greifswald that had attracted a great deal of local interest.
Appearance and morphology
Orcas are the largest extant members of the dolphin family. Males typically range from 6 to 8 metres (20 to 26 ft) long and weigh in excess of 6 tonnes (5.9 long tons; 6.6 short tons). Females are smaller, generally ranging from 5 to 7 m (16 to 23 ft) and weighing about 3 to 4 tonnes (3.0 to 3.9 long tons; 3.3 to 4.4 short tons). Calves at birth weigh about 180 kg (400 lb) and are about 2.4 m (7.9 ft) long. The skeleton of the orca is typical for an oceanic dolphin, but more robust.
Range and habitat
Orcas are found in all oceans and most seas. Due to their enormous range, numbers, and density, relative distribution is difficult to estimate, but they clearly prefer higher latitudes and coastal areas over pelagic environments. Areas which serve as major study sites for the species include the coasts of Iceland, Norway, the Valdes Peninsula of Argentina, the Crozet Islands, New Zealand and parts of the west coast of North America, from California to Alaska. Systematic surveys indic…
Feeding
Orcas are apex predators, meaning that they themselves have no natural predators. They are sometimes called "wolves of the sea", because they hunt in groups like wolf packs. Orcas hunt varied prey including fish, cephalopods, mammals, seabirds, and sea turtles. Different populations or ecotypes may specialize, and some can have a dramatic impact on prey species. However, whales in tropical areas appear to have more generalized diets due to lower food productivity. O…
Behaviour
Day-to-day orca behaviour generally consists of foraging, travelling, resting and socializing. Orcas frequently engage in surface behaviour such as breaching (jumping completely out of the water) and tail-slapping. These activities may have a variety of purposes, such as courtship, communication, dislodging parasites, or play. Spyhopping is a behaviour in which a whale holds its head above water to view its surroundings. Resident orcas swim alongside porpoises and other d…
Life cycle
Female orcas begin to mature at around the age of 10 and reach peak fertility around 20, experiencing periods of polyestrous cycling separated by non-cycling periods of three to 16 months. Females can often breed until age 40, followed by a rapid decrease in fertility. Orcas are among the few animals that undergo menopause and live for decades after they have finished breeding. The lifespans of wild females average 50 to 80 years. Some are claimed to have lived …
