In predatory species, the lower eues are usually high-performance eyes, which works because they swoop down on their prey and can control its capture in this way. In prey species it may be the other way round.

These gait models all look so lively! I'm definitely a fan! Do my eyes deceive me or do tetropters have four eyes on the top segment and another four on the bottom one?Petrhttps://www.blogger.com/profile/06537642993606964893noreply@blogger.comtag:blogger.com,1999:blog-5821098719340852065.post-37454196238676871342018-05-19T12:18:54.009+02:002018-05-19T12:18:54.009+02:00L13B3 14641: Many tetrapters are capable of holdin...L13B3 14641: Many tetrapters are capable of holding their wings at rest in the horizontal cross position, as well s in a vertical 'out of the way' position. I can see some of them flicking their wings from one to the other postion, attracting mates, or warning competitors, etc.<br /><br />I like the 'raptor' hidden in tetrapter. The Red baron iof a few posts ago certainly is a predator, but not very large. They are exoskeletal like spidrids. They can easily grow larget than their earth counterparts, so you can expect many spidrids as large as coconut crabs, and tetrapters as large as the extinct Meganeura. But not larger than that...

I believe dragonflies and damselflies respectively found quite similar solutions to a similar problem.<br /><br />Perhaps there are tetrapters that use either strategy? Or tetrapters with narrow, downswept wings. Though, personally I find upswept wings to be the more visually appealing solution. Just musing.<br /><br />It's interesting to me that tetrapters tend to be small. The portmanteau of "tetra" and "pter" evokes the word "raptor".

Tetropters cannot simply fold them over their backs out of the way, so they either just stick the wings out in all four directions or upwards. In a way butterflies and moths face the same problem: their wings are to large too fold away too, so there are only two options left: like an open book or like a closed book.

It's quite visually interesting.<br /><br />And I do hope that post on the possible strength of mammoths does does indeed come together, as that sounds like quite the interesting topic.Keavanhttps://www.blogger.com/profile/04083537800080891766noreply@blogger.com
