Triops already lived 220 million years ago and are thus the oldest still living animal species

Way of life of the Triops

The oldest animal species on earth

With the following prerequisites and characteristics, Triops already lived together with the first dinosaurs and saw them dying out again, resisting the extreme conditions that the dinosaurs drowned and now live just as 220 million years ago with the same survival strategy and the same appearance.

The Triops lives in temporary waters, which means that these waters exist only for a short time. These are usually caused by rainfall and flooding.
(more about this topic: Habitat)

The eggs of the triops are found in the sand or soil.


Indestructible eggs
                                                         Triops-eggs:
Triops-Eier

Since the triops have laid their dauers in the sand or soil, they can survive up to 30 years or even more, and can cope without problems with cold winters and hot summers, and can also cope with shocks, are now able to hatch the nuplets during the next flooding or puddling.
The eggs even undergo treatments in liquid nitrogen or boiling water. Toxins do not harm them.

It does not matter to the eggs whether they are already 1, 2 or even 30 years and more in the dry, water comes on the eggs hatch them, however not all.
In this way, they protect themselves from water drying that is too fast.
The eggs are only 0.6 - 1 mm in size and are thus hardly recognizable in the sand or in the soil.

A short but active life

Triops cancriformis

For example, In the spring the "great rain" and flood the Triopseiers, hatch within a few hours to day quite a lot of tiny about 1mm large Nauplien from the permanents.

To the topic "Nauplia" with pictures, here: Nauplia stadiums

In the first days, they go through 4 naturopaths and double to triple their size per day. After 3 - 4 days they have reached their final triops and will be sexually mature until the 8th - 16th day. They have already reached a considerable size of (depending on the type) 2 - 5 cm.

To the topic "The fully developed Triops" : The fully developed Triops

From now on, it is only eaten, grown and buried up to 200 eggs per animal in the ground.

After 6 - 14 weeks, the Triops have reached their final age and have grown up to 14 cm (depending on the species), as long as their waters have not dried out before.

A video of me from "Triops cancriformis", a species that is also native to Germany:

The animals were after the Video of course translated into a large basin)


Even the woman

Since in most of the species of triops male animals do not occur at all, triops must be able to breed young. This is done by the females copying their genetic material and storing them in the dauereiern. They clone themselves, so to speak, themselves. For species such as the Triops granarius, however, the proportion of males is 40% because this species must reproduce sexually.

Very rarely happens that a male is with "Triops longicaudatus", but I was lucky and could even film 2 films in the pairing:



For each size a new skin

Triops-Haut

In order to get to the next stage of development, and to grow larger, the triops must constantly skinn, as their chitin shell can not grow.

In the first few days they skinned 1-2 times a day, but they are getting less and less every day. The same principle is used by almost all the creatures, but they do not have to go through naturopathies, but have been fully developed creatures since hatching. When a triopic skins, it looks a bit spasmodic. He swims several times upwards and then winds very strongly, bend the tail in all directions and set up the tank. After about 1 - 30 minutes the act is mostly done and the trio slips out of its old cover, which then falls to the ground next to it.

Triops are omnivores that eat algae, insects falling into the water, mosquito larvae, and so on. Also earthworms are eaten. In their habitat, the temporary waters, they find this abundant. When the great rain comes in spring and the meadows and the earth are flooded, the first victims are already caught and drown: the earthworms. These later serve the triops as food. The earth, which has been rinsed and watered, contains many nutrients, where micro-organisms and algae multiply rapidly and serve the freshly hatched Nauplien as a first food. In the next few days, many insects come to the water to lay eggs. In this case, insects often stick to the surface of the water, causing them to be used as food. From the eggs of the insects hatched, the larvae hatch, for example, The mosquito larvae. This is a good, protein-rich prey for the Triops. Even dead friends are eaten. With this rich food supply, the primates can thus achieve extremely rapid growth. If extreme food poverty occurs, they even become cannibals.

Unfortunately today getting rare

The Triops cancriformis, which was native to us, used to be very often found in puddles, and nobody knew how they got there. So they thought they were raining down from heaven.

Unfortunately, our Triops are now even threatened with extinction, as more and more rivers are being straightened, and the floodplains are dry. Also, inconspicuous puddles are simply made of e.g. Farmers because they do not know that there is a habitat for triops. The meadows that float annually or where large puddles are formed are also unwittingly expanded into fields and the habitat for triops is getting smaller and smaller. In addition, the pots and puddles are contaminated by the fertilizers on fields.
