Why are penguins so heavy?
They are insulated from the cold - air AND water. The heavier bodies of penguins are the result of their special bone structure and the blubber that they carry. The blubber protects penguins from the cold. Also, unlike the majority of other birds, penguins do not have hollow bones, so are much heavier. The solid, as opposed to hollow, bones act as ballast to help them dive. Also, being solid, they are less prone to breakage from the stresses of swimming.
Do puffins have hollow bones?
Penguins do not have skeletons that are identical to humans certain things are different such as bone length and the presence of a tail in the penguin. But certain structures are referred to as homologous. example: the flipper in the penguin and the arm and hand of a human have the same bone structure just different bone lengths.
Are the bones of all birds hollow?
According to Wikipedia (19 Sep 11), all the bones in a bird are semi-hollow: they're filled with structural supports (like organic struts and trusses) and, often, air pockets. But, there are exceptions: some flightless birds (such as penguins, ostriches, emus) have only solid bones.Other answers:None of them are hollow. However, they are much less dense than the bones of mammals. Mammals have a thick, heavy bone structure that is almost solid to support the body weight of each creature on land against gravity. Because bird skeletons must be light enough to fly, the inside of each bone is filled with long, narrow marrow supports that gives the bone both strength and a lightweight structure. However, this also makes bird bones much more fragile than those of mammals. If the bones were to be completely hollow, there is a good chance that they would be so brittle that even flight itself would be dangerous.All of them are hollow but there are a few birds that don't have hollow bones, like the emu or penguin.
What structural adaptations of the birds help them to fly easily?
Hollow bones, light body, large lungs and compact skeletal system.
How ae bird bones different from those other animals?
Tobi says: Bird's bones are hollow to help them fly,obviously to reduce weight when they fly. Human bones, on the other hand, are not hollow. We need strong bones to do the things we do, eg: walking, skipping, jumping etc...
How are penguins bones different from other birds?
hollow
If a birds wings are hollow how does that affect its flying?
Yes as birds with hollow bones cannot fly for longer whereas penguins do not have hollow bones and are able to swim in rough tides for ages. Also non-hollow bones are stronger and tougher than hollow bones.
How do hollow bones in a a bird aid flight?
it helps them fly because their bones are lighter and its easier to fly with light bones. But birds with dense bones, such as penguins makes it impossible for them to fly
Which one characteristic do birds seem to have that other animals don't?
Birds have hollow bones. (Except for penguins, which now have solid bones to help them dive)

HOW does birds hollow bones affect flight?
it makes it lighter so it can fly easier penguins don't have have hollow wings and cant fly but they can swim better because they are less buoyant.
What animal has hollow or partly hollow bones?
birds have hollow bones to help them fly
