Killer Whales Orca Skull Mount - This mount serves the following whale skulls for an adequate mount: Killer Whale. Dorsal fins also exhibit sexual dimorphism, with those of males about 1.8 m (5.9 ft) high, more than twice the size of the female's, with the male's fin more like a tall, elongated isosceles triangle, whereas the female's is shorter and more curved. The false killer whale easily adapts to captivity and is kept in several aquariums around the world, though its aggression towards other dolphins makes it less desirable. [113] The arrival of orcas in an area can cause white sharks to flee and forage elsewhere. In captivity, they often develop pathologies, such as the dorsal fin collapse seen in 60–90% of captive males. [64][65] In 2010, the Far East Russia Orca Project (FEROP), co-founded and co-directed by Alexander M. Burdin and Erich Hoyt, filmed an adult male nicknamed Iceberg.

[47] More recently, complete mitochondrial sequencing indicates the two Antarctic groups that eat seals and fish should be recognized as distinct species, as should the North Pacific transients, leaving the others as subspecies pending additional data. [123] In the Aleutian Islands, a decline in sea otter populations in the 1990s was controversially attributed by some scientists to killer whale predation, although with no direct evidence.

Zygophyseter varolai is an extinct sperm whale that lived during the Tortonian age of the Late Miocene 11.2 to 7.6 million years ago. The killer whale shares with other odontocetes a three‐tiered arrangement of limbic, paralimbic, and supralimbic arcuate cortical lobules divided by deep limbic and paralimbic clefts (Figs. Leatherwood, Stephen and Larry J. Hobbs (1988). Maltese fossil From same collection. It is less likely than the killer whale to include other mammals in its diet, instead feeding primarily on fishes and eating as much as 5 percent of its body weight each day.
