Both male and female of the eastern Dobson flies can reach lengths up to five inches (12.5 cm), measured from the tips of their pincers to the tips of their four wings, which, when not in use, are folded along the length of their walking -stick-like bodies. Their wingspans can be twice as long as their body length, and the wings themselves are densely lined with intersecting veins. Additionally, Dobson flies have segmented antennae similar to ants and wasps.

Found across the eastern side of North America east of the Continental Divide from Canada to Mexico near flowing streams where the larvae grow up. The hellgrammites are the larva and they live under stones or occasionally on snags where they feed on a variety of soft-bodied nymphs of insects like the net-spinning caddisflies and blackflies

The adults catch theri prey with the long pincers that extent out of its head. They are so strong if your finger or toe got pinched it might bleed.

Dinosaur researchers heaven has been found in Tamil Nadu in southern India. Simply lying in large catches sticking out of the ground sand beds on grazing land are many nests of dinosaur eggs.

These eggs about 5 to 8 inches in diameter dating back 140 million years. These clusters containing eight eggs of spherical eggs of dinosaurs. They were lying in sandy nests of about four feet under volcanic ash from the Deccan eruptions.

The eggs, which may be 65 million years old, were from both the Carnosaur, an aggressive, predatory dinosaur, and Sauropods, long-necked herbivores that became extremely large.

How long would it take to hatch a dibnosaur egg if you had a viable egg?

No one knows for certain how long dinosaur eggs needed to incubate. Since birds are derived from dinosaurs the incubation period of dinosaurs can be is strongly correlated and guessed from the bird data. Length of incubation of avian-like dinosaur eggs is often correlated with egg weight. Here is a chart of the estimated incubation times for various the dinosaur egg types known.

They live near the seabed, living in depths from 5 meters (15 ft) to 360 meters (1200 ft). They are usually live alone. Jon dory

The fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. The dark spot is used to flash an ‘evil eye’ if danger approaches.

It grows to a maximum size of 65 cm (2 ft) and  weighs about 3 kg (7 lb) and has 10 long spines on its dorsal fin and 4 spines on its anal fin. It has microscopic, sharp scales that run around the body. The fish is an olive green color with a silvery white belly and has a dark spot on its side. Its eyes are near the top of its head. It has a flat, round body shape and is a poor swimmer.

The Dusky shark, and other large bony fish love to eat this fish and so does man.
