(Image 1 is of normal seradum. Blue red mark shows their tongue. Image 2 shows organs of base seradum marked red is a male marked blue is female this one does have an egg sack but normally they are only one gender.

they had changed a lot from their Ancestors. After the shaded meteor impact much of the world had died. This caused a famine and while many species started to fend for themselves some began to work better on working as a whole.
The freafs already moved together and helped eachother to some degree however once they began to have less food they began to work together more. Eventually this lead to the arise to a metamorphic lifestyle and two different cast.
These three different cast arose for 2 reasons.
1- they need to be moving constantly to get food.
2- they need to keep their eggs safe.
What better way to solve this issue other than to have a mobile armored hatchery? These are called matriarchs. The matriarchs are much larger than the rest of their herd. And are very often the leaders.
The matriarch has developed a horn ontop of their front segment. This is so when a matriarch encounters another herd the 2 matriarchs will try flip the other onto their back. Once the winner is decided they will inspect the enemy herds members. The matriarchs do so with their tongue.the tongues of matriarchs has changed to be a lot larger and more specialized. Their tongues have developed chemical sensors and pressure sensors. This helps the matriarch determine if a enemy herd has a strong member. If a herd does have a stronger member the winner will be taken into the winning matriarchs herd. And if the winning matriarch needs to she will leave a weaker member behind with the looser. This helps ensure that only the strong survival and helps to encourage competition.
And not only is the matriarch in charge of ensuring the strength of her herd but she is also responsible for a large part of Reproduction in the herd. While the females are capable of carrying their own eggs they much more often transfer them to the matriarch. This is done via the female spitting out her eggs and holding them with her tongue where she will hand these off to the matriarch. The matriarch will then take these eggs and will put them into her own much much larger egg sack where the eggs will attach to the inner layer of her egg sack and continue developing from there.
The next cast is more or less just average. They aren't specialized to fight or anything. They can be ether male or female. And they only have one goal.
Now all that doesn't mean they haven't changed. They are much more flat compared to their Ancestors making them much more stable. And their tongue had also changed to more muscular allowing for an easier time getting food.
And now probably the most dramatic change would be the young. Their tail had flattened out and formed segments allowing for it to be used as a paddle allowing them to swim. And to accommodate the tail 2 segments underwent big changes. The second and first segment(not including the head) had changed to give greater control while swimming. The first segment at first developed large flat plates so when they leaned they could better control turning. However as those fins first began to develop a need appeared for faster more accurate turning and that pushed for the ability to tilt these fins. This happened at first at the very bend of the armor it had softened but what point was it if they couldn't control it? And so some simple muscle attachments formed finally allowing them to tilt their new fins.
However that wasn't all. On their second segment they had formed simpler fins designed just to make them a bit more flat. This meant their would be more water under them and means they could spend less energy gliding through the water. And eventually when they reach a mature age they shed their first set of fins and the second will follow soon. At this stage they will become 1 of 2 genders.
SIZE—- a matriarch is typically twice as large as any other member. The smallest species is only a third of an inch while the largest almost reach a foot at 10 inches.
LOCATION—- with a wide range of species you cam find them almost anywhere in the ocean. From the shallow tides to the deep trenches and even the arctic.
HABITS/BEHAVIOR—- they are a very tight nit group. They travel along in herds wandering the ocean floor always looking for more food. They enjoy to have rocks nearby so in case of a predator they can face their gut to the rock for protection. However the young are very different. They use their ability to swim to its best swimming upside down near the oceans surface they look for any plants avaliable. And once they are old enough a seradum will form their own group. Eventually a matriarch will be selected and become the leader.
DIET—- herbivore- often they eat short flowers but they will also eat any other avaliable plants.
EXTRA INFO—- they are rather skittish when a sudden change happens in their environment. so if you keep them as pets don't switch up their cage! Okay? It really startles them.
OTHER—- they have a very earthy taste and taste similar to crab. I suggest boiling them as their shell will fall off on its own once it's heated.
