Islepede

The islepede replaced its ancestor the paddlepede. It has evolved in many ways to out compete its ancestor. 1st of which is its island gigantism. It has grown to 10 times its ancestor's size. Next is its new reproduction method. It now has sexual reproduction with 4 genders. A 2 males and 2 females. male A and female A make only males (of A and B) while male B and female B make only females (of A and B). This creates a greater diversity in genes than just one male and female. However it is harder to find mates. This is not a problem on an island with no predators (except for say rubric sticky-cubes). They have evolved "book lungs" which means they can stay on land. These passively take in air rather than breathing them in. Now that they are on land they must find puddles to lay their frog-like eggs in. This happens during the rainy season on the island. Thus they will mate only once a year to better their chances to find a mate. This can be difficult with 2 types of males and 2 types of females. Their bristly baleen in their mouths have become harder and more coarse like comb bristles. This helps them not only eat hard foods but they can rub them together to make a chirping sound. Male A and male B make different chirping patterns and pitches. Male A's tend to be larger than male B's as well. They are blind and cannot see each other so they must depend upon touch, taste, vibrations and now hearing. You see their middle legs have grown little hairs all over them that pick up sounds. These are so they can hear their mates. They also can use it for navigation by hearing where the sea is in relationship to them by the sound of the roaring waves. Now that most of their legs have became hearing organs they use their front claws as feet and their back tail as a big foot. The tail flukes not only are used as a foot but pick up vibrations in the ground. This helps them sense the minuet movements of the rubric sticky-cube. It has to be careful not to become its prey if it sits around for too long. However it also eats it as well as other relatives of the stickyball family. You see it has special saliva and digestive system in which it can eat even the very acidic rubric sticky-cube without becoming digested itself. They are active mostly at night to loose less water from their bodies. During the day they will sleep in hollows of the purple hurlchunks tree. Their front antennae have also evolved tiny gaspers on the end for picking up stickyballs and other food. There are many joints in the antennae and allows it to move in just about any direction. This along with their front claws can even allow some smaller islepedes to sleep in the top of the purple hurlchunks tree.
