Killer whales have 44 chromosomes; an excellent banding study was done on six killer whales that showed considerable polymorphism of C-bands; this is shown in the following picture (Arnason et al., 1980).

How many chromosomes do whales have?
The particular number of chromosomes is not unique to one species as for example other whales have 42 chromosomes, but the specific number is unique to a species as sperm whales always have 46. This number is tightly regulated and maintained. Alterations in this number can have dramatic consequences.
How many chromosomes do narwhals have?
THE CHROMOSOME COMPLEMENT OF THE NARWHAL (Monodon monoceros)
The chromosome number was found to be 2n = 44. The karyotype is similar to all other whale species reported except that of the sperm whale (Physeter catodon), and the killer whale (Orcinus orca).
Has a whale ever killed a human?
Killer whales (or orcas) are large, powerful apex predators. In the wild, there have been no verified fatal attacks on humans. In captivity, there have been several non-fatal and fatal attacks on humans since the 1970s.
Has any animal ever killed an orca?
When it comes to predator/prey relationships, the killer whale is an apex predator and isn't known to have natural predators. In fact, there are no known cases of a killer whale consuming a person. ...
How many chromosomes do blue whales have?
Blue whales have 44 chromosomes in every cell. Determine how many chromosomes you would expect to find in each of the following.
How many chromosomes does a tiger have?
Panthera tigris has 38 chromosomes. The karyotype has 16 pairs of metacentric and submetacentric autosomes and two pairs of acrocentric autosomes.
Are killer whales friendly?
Unlike sharks, killer whales don't typically attack humans unless they feel threatened, and in no known case has a human ever been eaten by a killer whale. For the most part, killer whales are considered amiable animals, at least as far as we know and have experienced them to be.
Can a human survive being swallowed by a whale?
Despite occasional reports of whales scooping people into their mouths, it's incredibly rare—and for all but one species, swallowing a human is physically impossible. On Friday, a lobster diver made headlines when he described miraculously surviving being “swallowed” by a humpback whale off Cape Cod, Massachusetts.
Is it safe to swim with orcas?
Is it safe to swim or dive with Orcas? Yes, however, you have to be very cautious, because they are still wild animals and need attention all the time. Orcas owe their name “killer whale” to the early whalers Because they apparently attacked and killed all other animals, even the largest whales.
Are orcas smart?
Orcas are highly intelligent, social mammals that have long been a part of marine park entertainment, performing shows for audiences. However, it's become increasingly clear that orcas do not thrive in captivity. They have evolved to swim up to 40 miles a day, foraging for food and exercising.
Would an orca eat a human?
From our historical understanding of killer whales and the recorded experiences people have shared with these marine mammals, we can safely assume that killer whales do not eat people. In fact, there have been no known cases of killer whales eating a human to our knowledge.
How many chromosomes does a dolphin have?
The karyotype of the bottlenosed dolphin and the pilot whale have been described and compared from a karyological evolutionary point of view. Both species have 44 chromosomes and the two chromosome complements are strikingly similar.
How many chromosomes does a potato have?
Common cultivated potato varieties include tetraploid (2n = 4x = 48) with a basic chromosome number of 12, while there are cultivated species at the diploid (2n = 2x = 24) to pentaploid (2n =5x = 60) levels.
How many chromosomes does a dog have?
A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39. How many chromosomes do humans have? Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes.
