Transcript of Killer Whales

The male killer whale is typically 5.8-6.7M, whereas the typical female size is 4.9-5.8M. However, the largest male size was 9.8 M and the largest female was 8.5m.
What we can do to help

each pod has distinctive noises that its members will recognize even at a distance
pods that associate with each other share certain calls, these pods are called a clan
rely on sound production and reception to navigate, communicate, and hunt in dark or murky waters
vocals are developed from mothers
Orca Communication
Mating Patterns
Comparisons of genders size
largest predator of warm-blooded animals alive today
individual ecotypes of orcas are often extremely specialized in certain prey
eat marine mammals such as seals, sea lions, blue whales, sharks and much more
swallow their food whole, or they may tear or shred it
adult orcas eat 2-4% of food in body weight daily
Orca Diet
Orcas
By Amy Huang, Ryan Bromley, Ellis Gao, Urvi Patel
Hunt Patterns:
have teeth that can grow up to ten centimeters (4 inches) long
known to grab seals right off the ice
hunt in deadly pods of up to 40 individuals
appear to be both resident and transient pods
different groups may prey on different animals and use different techniques

Amy's Sources:
whale hunting is incredibly cruel
Orcas hunted to exhaustion before they are harpooned
whales can slow breathing and heart rate, many that appear dead or unconscious are probably still feeling extreme pain
many painful deaths
animal advocates and the general public has put the captivity of orcas under scrutiny

The killer whale gives birth typically at any time, but prefers to give birth in the winter. They are a polygamous species, meaning that they may have multiple partners in a mating season. Males will typically reach sexual maturity at the ages of 6-10 and females will typically stop mating at the ages of 14-15 years old. It takes 15-18 months for females to give birth.

Daily life of a killer whale
pectoral clap


lives in pods of usually 5 to 30 whales, but a pod could have 100 whales in it too
fast swimmers, meaning they have time to rest and play
A pod of whale could surround a boat just out curiosity and want to play with it.
whales DON'T actually sleep.

Habitat
Killer whales live in many oceans, and pretty much all around the world.
found in almost all oceans, from the cold Arctic and Antarctic regions to tropical seas
usually lives in oceans that varies from 65 and 196 feet in depth
they are also found in swallow areas
Swimming
Killer whales are really good swimmers.
can swim at speeds of up to 45 kph (28 mph)
usually swim at much slower speeds, less than 13 kph (8 mph) for long periods of time.
not generally deep divers, foraging killer whales can dive to at least 100 m (328 ft.) or more.
opens its blowhole and begins to exhale just before reaching the surface of the water
quickly inhales and closes the muscular flap

Human Impact/Reasons For Endangerment
Killer whales are animals that don't really live in many areas that are inhabited by humans, yet we still have a negative impact on them.
Commercial hunting
Capture for human entertainment
Habitat pollution
Excessive noise
Decreased food sources
Collisions with boats
Problems with fishermen
Appearance
Orca whales are easily one of the most distinguishable and well known whale species there are. You often see these animals at amusement parks such as Marineland and Seaworld.
Appearance
Black on the top and white underbelly.
White markings near eyes
Grey or white saddle behind the dorsal fins
Average male sizes are 19-22 ft, and females are about 16-19 ft long
Cylindrical in shape with taperring ends, which is an excellent aerodynamic shape.
They have long dorsal fins and male fins are 1.8 m high on average, whereas females can be half that size.
Reasons For Endangerment:
saddle
Populations
The exact population of the Orca whale is unknown, yet researchers say that there are at least 50 000 living in the wild as of now. These whales are found in many oceans, and in cold, temperate coastal areas.
Specific Population Numbers:
25 000 whales are expected to live in Antarctica
8 500 in the tropical Pacific
2,250–2,700 orcas off the cooler northeast Pacific
500–1,500 off of Norway
Approximately 2 300 are estimated to have been seen off the coasts of Japan
Killer whales are very active animals. Killer whales do activities that can be divided into foraging, socializing, traveling and resting.
Orcas are carnivores and are at the top of the food chain. They don't have many natural predators.
These animals are highly intelligent and they can easily outsmart many of their prey.
Orcas make a wide variety of communicative sounds that include whistles and echolocation.

Types of killer whales
We, as humans, have inflicted so much pain, both physically and mentally, on the Ocra population. Calves are torn from their mothers to entertain us at theme parks, the mothers are often killed by hunters for blubber and meat.
Some things you can do are if you see one, report it so that scientists and researchers can help it.

Tell people about the problem.

Don't pollute, as it is bad for the Orcas. Fun fact, the great pacific garbage patch (yes that's a real thing) is 0.41-8.1% of the pacific ocean.
Try to stop Sea worlds terrible ways. They cover up their sunburns with black zinc oxide. Orcas have a shorter lifespan in captivity. They get kidnapped or killed, and sent to sea world.
