I'm not sure if anyone has posted this yet, but has anyone heard of the Hemiceratoides hieroglyphica? It's a moth in Madagascar that stabs sleeping birds in the eye and then drink their tears. It's really an odd function.

Here's a link:

Vomeronasal organ

Jacobson's Organ
The Jacobson's organ also helps some animals perceive other chemical compounds besides just pheromones emitted between species. For instance, snakes find their prey by using their Jacobson's organ. A snake places its tongue on its Jacobson's, or vomeronasal, organ after having its tongue in the air. The snake touches its tongue on the two pits by the Jacobson's organ to allow it to properly sense their prey. The reason snakes have a forked tongue is so that the tongue can touch these pits. The deeper the fork in a snake's tongue, the more the snake uses its Jacobson's organ.

Snake sense - how snakes smell, taste, hear, detect body heat from prey, and see

I wasn't sure where I should put this, but this thread seems like the best place. I found a video that shows the difference between a food-chain on paper, and how one works in real life. This video shows a conflict between a group of lions, a herd of buffalo, and a crocodile. It starts of kinda slow, but picks up eventually (about four minutes in).

Hopefully this will give some inspiration when making the relationship between organisms and their prey.

Welcome Everyone
This is the main forum for the original Sagan 4 game. As you may know, there are two versions of Sagan 4, Alpha (the original) and Beta (the reboot). This is the new home of Alpha.

Introduction
Sagan 4 is an alien planet ecosystem project originally started by Hydromancerx inspired by Carl Sagan's video. Life on this alien planet started from a single cell organism. It is now populated with many species of flora and fauna all created by artists who love drawing and xenobiology. Members can pick an extant species, and design a possible descendant. If the organism is accepted, you or another member next generation can design their own descendants from this.

We have a Discord, but the main home for the game posts are here. Please check out the Main Game section to further learn details and participate in the game.

Thriving = 30 or More
Healthy = 20 to 29
Vulnerable = 10 to 19
Endangered = 2 to 9
Critical = 0 to 1[/QUOTE]

Note these are the allowed disasters. Things like alien invasion are not allowed.

Back when they were making the game Hydro, Oviraptor, Yokto, Krakow Sam and Huggkruka posted 2 species per day for a week and some of us for 2 weeks.

I bet you new people cannot post 2 species per day for a week!

"Assigned Species" is a very old game in Sagan 4. Back in week 2 when there was only a handful of species LadyM would randomly choose species for each of the team members to evolve. For that week we could only evolve from those picked for us. This ment we could evolve from our own decedents we made that week but we could not do any other lineages.

I challenge those who think they are skilled enough to take this challenge. If you take it then I will assign you 1 microbe, 1 flora and 1 fauna. In which you can only evolve from those 3 until the end of the week. Who is up for this very difficult challenge?

This its merging the "species swap" game with "adopt a biome". You basically pick a biome that the other should adopt. And then the person has to make 5 species for the biome the other one picked. Note that if you have never gotten the "Biome Adopter" badge then you will instantly get it if you make all 5 species! Pretty cool eh?

Game Made up by Nergali

Current Rules
1. All members can join.
2. Sign up date ends a week after announcing the mystery species, so join soon.
3. Contestants work on their splits.
4. A week after sign ups is the submission period.
5. All contestants must post their split in typical submission format on this thread.
6. Poll is held, the winner is chosen.
7. The winner gets to chose the organism for the next contest.
8. Repeat.
I recently had a concept for a contest that I proposed to Hydro. With his approval, I am now posting it.

The main premise is this: An organism is chosen, and then the contestants who have signed up for this contest will develop splits for it. Once the due date arrives, these splits are posted on this thread. A poll is then held, and the creator whose split wins get to choose what the next organism will be for the next contest, after which this all begins again.
Contests so far:

1. Dial K for Krugg
2. Night of the Charybdis
3. I Was a Teenage Cave Swarmer
4. Revenge of the Glacial Sauceback from Sagan IV
5. Invasion of the Colonial Trapinout
6. Sagan IV vs. the Gushlych
7. The Boneflora that Wouldn't Die
8. Hallucrastrums from the Deep
9. 20,000 Rojs Under the Sea
10. A Shockscooter to the System
11. Srugeing Rising

Hydro's Swap List

Swap people owe me...

Colddigger
- A Thermoworm Tufted Thermoworm split.

MNIDJM
- A Charyflora descendent.

This is a fun little game you can play with a fellow team member. Rhodix and Hydro are going to be trying it out. If you find a fellow team mate who is willing to play. Then you each choose a species you want evolved. Then the other person evolves the one you picked. This way a new point of view is created.

Rhodix picked the Seadragolden for me and Hydro picked the Armored Trapinfilter for him.

You can choose your own species to have someone to evolve or pick one of your favorites.

Here is a list of all the game, contests and challenges that we have and had here at Sagan 4.

Trading
Species/Landmark Swap
Species Split
Will Make Your Ideas
Something like a Swap

Complete any 10 of these challenges and get the "Challenge Master" badge. Only newly made species will be excepted unless they were on the past challenge list.

#1 - Save the Rainforest
Your challenge is to evolve a "tree" species in the Tropical Rainforest, Temperate Rainforest or Taiga. To be a "tree" it must be over 2 meters in height.

#2 - Hey Buddy!
Your challenge is to evolve species that depend upon each other and co-evolved. For instance plants and insects where plants produce flowers and the insects like bees pollinate them. Choose any 2 species alive and have them evolve in the same biome together and depend upon each other to live. Note you must post both during the same generation. Please do not choose species that are already doing this. In short they should mutually benefit from each other.

#3 - Islanders
Your challenge is to evolve island species. Choose any isolated island. Remember the species must come from a species already living on the island. Remember to use island phenomenons such as gigantism like the Komodo Dragon or dwarfism such as the Pygmy Mammoths.

#4 - Leap Day
Your challenge is to evolve a species that leaps, hops or jumps around. This is to celebrate "Leap Day" on Feb 29th.

#5 - Easter Eggs
Your challenge is to evolve any species that lays Hard-Shelled Eggs or is an Ovivore (aka. Egg-Eater). You get a bonus if it is both. And a double bonus if the eggs are colorful (with a good reason why). This is to celebrate Easter!

#6 - Curiouser and Curiouser
Your challenge is to evolve two "Alice in Wonderland" themed species. However one must be a a "fauna" and one must be a "flora". These can be anything from A Jabberwocky, singing flowers, cherish cat, mock turtle, or even a mad hatter themed species. Try to be creative and be weird! Good Luck!

#7 - Creatures of the Night
Your challenge is to evolve a species that is nocturnal (is awake during the night). This can be fauna (like bats) or even flora (like flowers that only bloom at night).

#8 - Blast from the Past
Your challenge is to evolve a living species from 100 generations ago or older.

#9 - See No Evil, Hear No Evil
Evolve a macro species that has no eyes and no ears.

#10 - Tool Maker
Evolve a species that can uses tools. This can be as simple as using rocks to open nuts or using twigs to into bug mounds.

#11 - Builder
Evolve a species that builds a shelter such as a beaver lodge, termite mound or woven birds nest. Note that simple hole burrows or leafy nests do not count. They must be difficult to make.

#12 - Master of the Elements
Evolve a species that can swim, fly and walk. (Ex. Duck) Bonus if it can live underground too.

#13 - The Big Leagues
Evolve a species over 10 meters.

#14 - Isolated
Evolve a species who only lives on a specific landmark.

Logcrusher (Shinglesaurus oblidicarius)
Creator: Bufforpington
Ancestor: Pebbleback
Habitat: Maineiac Volcanic, Maineiac Temperate Woodland, Maineiac Chapparal, Maineiac Boreal
Size: 2 m Long
Diet: Herbivore (Drooping Orbion, Bristlebranch Treebion, Baebula, Prutabula, Prutarbor, Octovinbion, Maineiac Glasstower, Glassbarrel)
Reproduction: Sexual, Two Genders, Amniotic Eggs

The logcrusher has split from its ancestor. With the evolution of predators on Maineiac island, some pebblebacks began to evolve defenses. One of the first was the re-emergence of its plates. They also became larger, making them available to fewer predators. Some began to become more aggressive, developing sharp beaks and a horn-like protrusion from its skull, which they use to attack smaller predators that are foolish enough to attack it. They no longer graze on low-growing vegetation, but rather eat the leaves of trees. Unable to reach them, they now use their very powerful jaws to gnaw through the trunks of trees and cut them down, sometimes eating the wood in the process. They also feed on the fruit of the prutabula and prutarbor. They also will graze on larger glassflora species. Their destructive tendencies often put them at odds with fruitsnappers, who will openly attack them as soon as they 'realize' the tree their nest is on is being cut down. Fruitsnappers are usually able to chase off individual logcrushers. However, they can do little to a herd, as the herd will strike back, eventually forcing the fruitsnapper to abandon its nest or killing it by crushing the fruitsnapper with their beaks. They have become purple in order for them to blend in with the forests they are commonly found in. logcrushers live in herds consisting of a single dominant male, females, and the females' offspring. When adolescent males reach maturity, they are forced out of the herd. These solitary males will search for other herds and challenge the males of said herd, attempting to take over. Males usually fight to the death, with the victor taking over the herd. Males will fight by biting, headbutting, and clawing. The same could be said when logcrushers fight smaller predators and fruitnsnappers in general. Their mating season normally begins in the summer. Because they now live further inland, they have developed amniotic eggs in a similar manner to the camoback. Females will dig out nests and lay their eggs into them. The eggs incubation period is rather short, due to the logcrusher's nomadic lifestyle. When the eggs hatch, the young are able to stand up and walk quickly. This allows them to keep up with the herd, which will leave as soon as all of the eggs hatch. While they are generally more aggressive than their ancestors, they still tolerate maineiac uktanks, as they allow the logcrushers to detect predators with greater ease. In return, the uktanks get protection from the logcrusher herd.

False Poison Pedesorm (Contegovermis bates)
Creator: Bufforpington
Ancestor: Armored Pedesorm
Habitat: Maineiac High Grassland, Maineiac Volcanic
Size: 5 cm Tall
Diet: Herbivore (Octovinbion, Brieneux, Maineiac Glasstower, Mainestalk, Pilunoroot, Glassbarrel, Pioneeroots, Marbleflora, Glaalgaes, Cryobowls) Frugivore (Prutabula, Prutarbor) Coprophagic, Detritivore, Scavenger
Reproduction: Sexual, Two Genders, Snail-Like Eggs Buried Underground, Very Fast Breeder

The False-Poison pedesorm split from its ancestor. It has developed the ability to dye its shell with pigments it naturally produces, which is excreted with the materials that create its shell. Some of these pedesorms started excreting dye in patterns and colors similar to that of the poison pedesorm, confusing predators into thinking they were actually poison pedesorms. Over the generations, these mutant armored pedesorms began to evolve to look extremely similar to its dangerous cousin, ultimately leading it to becoming the false poison pedesorm. In order to better mimic the poison pedesorm, its body and trunk-claw has become shorter and it developed claws on its tiny hind limbs. It also has darker skin, similar to that of the poison pedesorm. Even the shape of its shell and legs has become similar to the poison pedesorm. However, it still is relatively different, as its trunk-claw is better suited for cutting than digging, and it has far more developed eyes. One of the most striking differences though is its diet. Unlike the poison pedesorm, which only eats detritus and dung, the false poison pedesorm is also an herbivore, like its ancestor.
