Triops is a genus of small crustaceans in the order Notostraca (tadpole shrimp). The long-lasting resting eggs of several species of Triops are commonly sold in kits as pets. The animals hatch upon contact with fresh water. Most adult-stage Triops have a life expectancy of up to 90 days and can tolerate a pH range of 6 to 10. In nature, they often inhabit …

What Is A Trilobite? Trilobites were a very diverse group of extinct marine arthropods.

The phenomenon of adaptive radiation was first observed by Darwin when he travelled to a place called Galapagos Island. There he observed that there were finches with different types of beaks.The trilobite cephalon (orange) is the most anterior of the three trilobite tagmata (major body sections). It bears eyes, mouthparts and antennae, and articulates with a thorax (yellow) of multiple articulated segments (that in some species allowed enrollment), and a pygidium, (green) or tail section of fused segments.

Trilobites ("three lobes") are extinct arthropods. They were the first animals known to have eyes, although some were secondarily blind. They were very numerous during the early Palaeozoic era.

Two lines crossed the body of the trilobite, making it appear to be in three parts. Trilobite means “three-lobed creature.”

Schizochroal Eyes. Like flies, undersea creatures known as trilobites had “compound eyes” made of dozens of tiny lenses. Each individual lens usually produces a blurry image. But certain trilobites (order Phacopida) had special lenses that produced crystal-clear images, even on the murky seafloor.

GO. Trace fossils or ichnofossils are indirect evidence of the behavior and activities of past life. Trace fossil examples include tracks and trails, borings and burrows, gastroliths and coprolites and, rarely, imprints of skin, fur or feathers. Interpreting trace fossils can be very challenging.
