Pets & Animals

A:

The largest known carnivorous dinosaur is the Spinosaurus, which is so named thanks to the gigantic spikes that run down the dinosaur's back. These spikes form a "sail" that likely evolved to ward off enemies rather than predators. The Spinosaurus was likely too large to be preyed upon by other dinosaurs.

    • Can chicks communicate before they hatch?

      Q: Can chicks communicate before they hatch?

      A: Researchers at the University of Cambridge's zoology department have found that nesting mother birds do communicate with the embryos inside their eggs, though not through vocalizations or any other standard form of communication. Rather than Tweeting or tweeting, the mother birds in the study, which were all canaries, deposited hormonal information in their eggs that lets chicks know how well their parent will provide for them once they have hatched. The motivation behind this form of communication is related to a parental desire to control begging behavior in the chicks; if the embryonic chicks receive information that they will be well fed once they are free from their eggs, they may beg for food less aggressively.

    • Which came first, the chicken or the egg?

      Q: Which came first, the chicken or the egg?

      A: There are two ways to look at this question - either relating to eggs in general or to the chicken egg specifically. Either way, the answer is the same: the egg came before the chicken. In the case of eggs in general, animals such as dinosaurs were laying eggs long before the modern chicken came into existence, meaning that in this sense, the egg predated the chicken by thousands of years. As for the chicken egg specifically, according to NPR's Robert Krulwich, the modern chicken was hatched from an egg, meaning the egg came first.

      Q: What is a dragonfly's habitat?

    • Where do dragonflies live?

      Q: Where do dragonflies live?

      A: Dragonflies live around freshwater and lay eggs in freshwater, usually on plants. Dragonfly larvae have gills and live underwater. When a larva is mature, it climbs out of the water and molts, following which an adult dragonfly emerges from the shed skin. Adult dragonflies live around water as well but are capable of flying long distances in search of food and mates.
