brachiosaurus
The fore limbs are longer, yes.
A Lion has four limbs (legs) two fore and two hind.
fore legs and hind legs. Fore legs are the two front ones.
Frogs push off their back limbs to jump, which makes them more powerful
Example of vertebrates (having a spinal column) could be humans, whose fore limbs are arms, as we stand upright. Then there are animals like the horse, whose fore limbs (indeed all four limbs) are actually legs.
It was a huge dinosaur - the fore-runner of reptiles.
The hind limbs are much longer than the forelimbs, but forelimb to hind limb ratio is quite variable. Toads and toad-like anurans have relatively short hind limbs.
The forelimbs of frogs are primarily designed to support the hind limbs during sitting and walking. The back limbs are the ones designed for jumping.
A Tasmanian devil has bilateral symmetry, as usual for mammals. One unusual feature of this animal is an asymmetric running gait. The fore limbs move normally, but the rear limbs don't. The fore and aft motion of the left rear-leg is very noticeably shorter than that of the right - the devil runs as if one leg is injured.
Seals have around 34-36 bones in their fore-flippers (front limbs) and about 26-30 bones in their hind-flippers (back limbs), totaling to approximately 60-66 bones in their skeleton.
Yes. A walrus has fore and hind limbs that are modified into flippers. The foreflippers have tiny claws and the hind flippers have large claws on the three middle digits.
Joint legged animals are also called Arthropods. Here are a few: arachnids Oscorpions daddy-longlegs mites & ticks piders horseshoe crabs centipedes millipedes insects
