I wanted to transplant another of my projects, well, part of the future is far. Although my project is focused on the future of life on Earth, extraterrestrial life will be included as well, because humans will become a race to colonize various extrasolar worlds able to sustain life. Also, I will show some of the hypothetical life forms inhabiting some celestial bodies in the Solar System that supposedly could be suitable for life.

Europa
Quote:
 
For decades it had been proposed that Jupiter´s moon Europa may harbor life beneath its thick ice sheets. The suspicions about the possibility of life were only confirmed when unmanned probes lowered to the inner ocean were able to recover the frozen corpses of some organisms that surfaced up to the ice sheets. Although the remains were scarce, incomplete and damaged both by glaciers crushing and solar radiation they were sufficient to promote a research on the possible ice ecosystem. A special underwater probe supplied with a drill boosted by the first nuclear fusion-driven engine, which could melt and break through the ice, was sent. Silence reigned for a whole week until the first images of the probe showed a cephalopod-looking organism tampering the lens. Soon, more and more creatures were photographed, confirming Europa as the first celestial body with complex life known besides our own. During the Colonization Era the entire ecosystem below the icy surface was catalogued. Common features among the “Europarians” were the ability to perceive electric fields, and all invertebrates and that most of them lead an inactive and sedentary type of life.

Among the groups that can be classified and mention are:

Europazoa: the kindom in which the different organisms were classified, they are composed of eukaryotic cells but with a different structure.

Palpomorpha: a group of organisms similar to the cephalopods of the Earth, they are characterized by having a type of pseudoskeleton, electric receptors which allow them to detect and capture different organisms, and jet propulsion. Their life cycle is pretty similar to that of the Earthly amphibians. They are divided into two subgroups.

A) Palphoteuthida: They are among the most advanced organisms in the moon. They possess two pairs of tentacles on their jaws, 3 pairs of electric sensors and jet propulsion. Their sizes range from a few centimeters to more than 5 m of length. They are the apex predators in Europa, filling most of the predatory niches. They are also very sociable; some species even travel in school formations.

B ) Palpolarvidae: the representatives of this group have developed neoteny and fill lesser niches. Their appearance resembles that of the abyss fishes. They have a proboscis-shaped mouth which enables them to catch their food. Unlike their cousins, they do not move by means of jet impulse, but they have developed a set of fins.

Canceraluda: the closest things to the arthropods that can be found in Europa. Their measure varies from planktonic size up to 1 meter of length. The representatives of this group possess radula jaws which allow them to scratch the bottom, crush shells and even stab soft-bodied creaures. They have been classified into a great variety of groups.

Bibriomorpha: similar to sponges and coelenterates, they are sessile or inactive beings. This is the biggest group, and contains the largest organisms in the moon, reaching approximately 40 m long. They have a primitive nervous system similar to that of the flatworms, a rudimentary digestive system and some kind of muscular system.

Alucilethidae: kindred with Palpomorpha, these organisms are similar to the echinoderms. They have a cartilaginous structure which helps them to stay afloat, and allows them to keep their body rigid. They also have the ability to create strong electrical pulses from the muscles of their fins.

Ganymede

Another of the moons of Jupiter, the suspect also possible that life could exist on its surface. There was much interest because the thick ice that made it more difficult for the ocean. The discovery did not come through a tube, but for humanity in person. During the years of colonization, special bases were established in Europe monitored the activity. Small groups of curious scientists began to melt small holes deep into weak areas of the ice sheet to verify the resilience of life in the background. But they realized that there was also life to find swimmers organisms like worms. Achieving send probes submarine to the bottom, it was discovered another enclosed ecosystem, but, unlike Europe, less developed, due to limited space and extreme conditions. The classification of the groups is as follows:

Criptozooa: the kingdom can be classified into Ganymede

Artropoconida: a group of organisms similar to terrestrial molluscs, live on the seafloor as detritivores. They have a segmented shell that allows them to move more and simultaneously protect the wound on large bodies themselves, there are a variety of shapes, sizes up to 1 meter.

Gastronectidae: are free-swimming organisms chubby. They use their mouthparts local carnivals swim, allowing them to also trap nutrients at once, some of them are as big as an orange

Tenontomorpha: flat wormlike creatures are predators that can reach several centimeters des two feet

Blastobaros: with a maximum size of 3 cm, are creatures like sea cucumbers that roam the flat plains.

enceladus
Quote:
 
This moon from Century 21 is observed geysers activity arising in the planet's south pole, throwing huge amounts of water vapor, suggesting that as the moons of Jupiter, may have an ocean. And as I suspect, it does. After studies at the South Pole was determined that under the cloak of that hemisphere, was an ocean. Only discovered life by studying the geysers aliens, apparently, not only throwing steam out of the moon, but also microorganisms. Expeditions using the same technologies that helped find life in Europe, managed to capture first enceladico ecosystem. Oceans of Enceladus were unique. Unlike the last two findings, the agencies here were very small, barely larger than a mite, due to the extreme conditions and rough that caused that more complex organisms do not evolve. Despite that, the biodiversity found was much higher than had been expected. They are classified as follows:

Thermozooa: the kingdom Enceladus most advanced, most protozoa resemble land.

Bacilognatos: type creatures protozoa are major predators of the ecosystem. May be at least 2 mm in diameter. They have several mouths like appendages that allows them to capture different organisms.

Paramoebas: detritivores, abound on the ocean floor of Enceladus. Oviles organisms are larger, some, reaching the size of 2 cm long.

Balanusoides: larger bodies of Enceladus, some up to 15 centimeters. They live up on the walls of ice and seafloor vents. Their life cycle begins as a flagellate-like creature, which to find a suitable place to live, is buried and then begins to grow.

Erithocilius: these creatures are beings similar to heliozoa of our oceans. They live mainly in volcanic vents on Enceladus. Most live free in the ocean, although some species are anchored to the bottom and go through life being sessile.

Sphermatomorph: betónicas creatures that form large swarms of up to a kilometer long.

Spinopoda: relatives of Erithocilius are active creatures that live on the bottom or walking on the ice walls, looking for food with their tentacles.

Palopoda: these organisms, is believed to be the ancestors of the Bacilognatos possible, as they feed using their large pseudopods. They are irregular bodies floating in the oceans. They have a kind of suction cup that allows them to cling to prey.

titan

This moon is considered as another candidate in the solar system that could support life, though not equal to the carbon-based life. Due to its composition, it has been thought that may evolve chemically different life forms known to mainly silicon bases. Even when he made the discovery, scientists were surprised to find some creatures carbon. Complex organisms were found that supported the extreme cold weather and the moon. Even more amazing was the finding other living organisms to tens of kilometers beneath the ice, an ocean of water and ammonia formed the planet's mantle while a habitat for an ecosystem more active than the surface. This was a source of debate about how life must have arisen in Titan. Many felt that life had emerged on the surface and after a few million years this could emigrate to internal ocean, on the other hand, suggests that life on the moon arose in the internal ocean and eruptions of volcanoes ice, these creatures managed to surface. Many favor of surface origin because biochemistry. Still, the controversy continues. Several groups have been classified, many of whom live in the two ecosystems, and few only live in one. It describes:

Ciliognathans: molluscan creatures are detritivores, living both on the surface and in the internal ocean. There are two groups:

1. ankilogymno: this group lives in the area, near the oceans of methane. They are larger organisms that can be found in lakes of methane, some up to 10 cm long. They have body armor that helps them against predatory species Hidramorpha.
2. Loligomorpha: this group lives exclusively in the internal ocean. Gelatinous creatures are swimming freely and feed on the seafloor, using its tentacles to catch food and then digest it. Inside their bodies, has developed a type of bone that keeps its shape. This is a modification of the plates of his relatives in the area.

Hidramorpha: a group of gelatinous organisms like coelenterates of the earth, they occupy most of the niches sessile, both on the surface and in the inland sea between the groups found are:

1. Petromorpha: major predators on Titan, some up to 20 cm long. Most are ambush predators that lurk in the mud of methane.
2. Hidrapoda: commonly called, jellyfish centipedes, these organizations reach lengths of up to 50 cm. Creatures are active, although most of the time they spend immobile in cracks waiting for prey

Allozoids: are so far the strangest bodies found on Titan, since despite being related genetically, morphologically very different. The unique characteristics that are related, they have a cord neuronal instead possess a mouth radula and also you can perceive and produce magnetic fields. They are the only order of creatures that can live in both the surface and inside the globe, without the need to adapt to each specific medium, ie in the life cycle of many species of these groups, can go from living in the seas of methane, the ammonia-water seas. Among the specimens found are:

1. Onicophomorpha: these arthropod-like organisms live in both the ocean surface and the interior of Titan. They have the greatest diversity of species with at least 500,000 counted. Occupy niches secondary consumers.

2. Dumbomorpha: these organisms are benthic swimmers, from a few millimeters in diameter. His name is because they have two big fins allowing them to make a variety of movements.

Placomoebas: the most important bodies in the ecology of the surface of Titan, they make up the entire flora of the planet, its size is not larger than 5 mm.

Note: Do not want to talk about the biochemistry of life on Titan to be difficult and complex, is likely to develop, but not right now.

triton
Quote:
 
After the discoveries made in each frozen moon in the solar system, it was thought that everything was found alive, but did not. A group of settlers biology buffs, embarked for Neptune's moon, Triton, because this showed the same signs geological permitting life on other moons. After digging into the ice, no disappointments, found the ecosystem further from our solar system, while the most primitive, with just as large organisms like amoebas. Still, the discovery of these bodies is amazing, because it seemed that some of them may have lived in the area. Besides that, they found criofósiles (a term given to find bodies trapped in the ice and suffering the same processes of normal fossils). He proposed the theory that Triton was once a Titan-like moon was in its earliest, but for some reason, the atmosphere is quickly eroded.
Here are the groups found:

Picnogonoids: creatures as large as a mite. live at the bottom of the ocean.

Phirannapoda: a group of protozoa-like creatures are the main predators. use their pseudopods as jaws

Cocolomorpha: a strange group of organisms, as each one of the cells that has a specific function, such as organelles.

Swekegnatos: long, slender bodies. developed at the tip of their mouths, let them armored pseudopods break, pieces of ice.

Kritauri

is an exomoon orbiting the planet elekator, to more than 20 light years from earth. This is the world with the most advanced ecosystem that exists around us, besides being the first.

during the stay human, in kritauri, began to study hard geological history of the planet. were uncovered something interesting: the chemistry of kritauri was totally different from her nearby moons, in addition, the fossil record showed that the flora that had evolved from 650 mya to 498 mya were warm weather, which then abruptly changed and a lot of it died and was replaced by a flora adapted to colder climates. Another interesting thing was that it had been observed that some of the system's planets were in areas where there would have to be. this led to a radical theory: the possibility that a large object all planets move sytem.

Based on this theory, it was this timeline:

580 mya: believed to kritauri since its formation, and its orbiting planet, elekator, Munds were separated.

520-505 mya: Based on calculations, it is believed that in this period, a large celestial object (possibly a star) pass near the exterior of the star system, which caused several planets out of their orbits.

505-500 mya: over a period of thousands of years, elekator, was released soar into the system, but not hard enough.498 mya: elecator kritauri and, being very close, made ​​the first began to be drawn into the orbit of the planet, causing serious natural disasters and mass extinctions.

495-490 mya: kritaury stabilized and established an orbit around the gas planet.
