In each ear, the middle ear cavity is expanded into a complex sinus on the skull base.
Does a whale have a skull?
Whales have real bones. ... The skeleton of a whale consists of a skull, a backbone, a rib cage, and a collection of bones that are part of the flipper, but correspond closely to the bones in the human arm and hand.
What are animals without bones?

Do jellyfish have Endoskeletons?
Porifera (sponges) and cnidarians (jellyfish) are invertebrates that have a form of endoskeleton called a hydrostatic skeleton. ... In order to grow from infancy to adulthood, organisms with exoskeletons must shed or 'molt' their outer skeletons and then grow a new one. This is not necessary with an endoskeleton.
Does snake have skeleton?

Why do whale skulls look like that?
Some whales are wonky. You might not know it to look at them, but their skulls are actually incredibly asymmetrical. This mysterious feature helps with echolocation, the way that whales work out where things are by making sounds and sensing how they are reflected back.
Where do dolphins pee from?
Dolphins urinate in the water in which they swim, making it difficult to measure their urine output.
What animal has the biggest skull?

Do killer whales have skeletons?

Is a blue whale's heart?
A blue whale's heart is the biggest on the planet, weighing 400 pounds. That's the weight of about 35 gallon paint cans.
