The hedgehog's back contains two large muscles that control the position of the quills. The average hedgehog has about 5,000 to 6,500 quills that are strong on the outer surface but filled with air pockets on the inside. When the creature is rolled into a ball, the quills on the back protect the tucked head, feet, and belly, which are not quilled.
In the 1970s, a gene related to how our brain grows our limbs was given the name âhedgehogâ in relation to the spiky appearance of fruit flies with a defective version of the gene.In 1995, three strains of the âhedgehogâ gene were found and named âDesert-Hedgehogâ, âIndian-Hedgehogâ, and amusingly, âSonic-Hedgehogâ.onic Hedgehog Homolog (SHH) is one of three proteins in the mammalian hedgehog family, the others being desert hedgehog (DHH) and Indian hedgehog (IHH). SHH is the best studied ligand of the hedgehog signaling pathway.
