Gibt es auffällige Weibchen in der Tierwelt?
Hallo ihr Lieben,
ich wollte mal fragen, ob jemand von euch eine Tierart kennt, bei dem das Weibchen auffällig ist UND das Männchen unscheinbar.
Es wird immer gesagt, dass meistens bzw. in der Regel die Männchen ein auffälligeres Fell oder Federkleid haben (z.B. Pfau) aber es muss ja auch ausnahmen geben oder nicht?
Ich habe auch schon versucht danach im Netz etwas zu finden aber leider nichts gefunden 🙁
Vielen Dank!

In any case, in most spiders from the group of the so-called orbiculariae, including the hood net spiders and also in the crab spids, the females are much larger and often more colorful. However, less due to sexual selection, but because there are warning colors or camouflage colors on flowers and they have to carry the many eggs in the body. Some thousand. The males only have to get to the female unaware and are smaller and inconspicuous. A spectacular domestic example is the puppy spine. Or not secretly the spiny orb weaver and the golden silk spider from America.
For example the Southern Tomato Frog (Dyscophus guineti). There the females have this striking tomato color, but the males are yellowish or brownish. The males are also smaller.
Thank you. Do you happen to have another animal? Can also be insects 🙂
There are some birds. You’d have to find this article:

Of course, they are looking at the exceptions because they are particularly revealing.

This deep sea fishing fish. The male, in pocket format, is just a hindrance so that the female can give it to young people. They stay together when they find themselves.
With the worshippers, it is believed that the females are much larger.
Yes, that’s true, the black widow is sure. But I am looking for an animal that is more noticeable with its colors and patterns;) Thank you.
In the case of Thorshühnchen and Odinshühnchen, the males pull up the boys and are simply coloured. Because of the short summer, the beautifully colored female gave several males the eggs to get the kind.
In dogs, cats, guinea pigs, mice, rats, rabbits, horses, zebras, polar bears, bears, tigers, giraffes, etc…. there are in appearance related to No differences!
I only know a subtle way:
Homa sapiens sapiens
And with this, the ethologist would argue that honest signals are widespread in nature and that natural selection in females always produces only honest and low-cost signals.
So exactly what a modern woman of the present not !
