- The guppy (Poecilia reticulata), also known as the millionfish, is one of the most popular freshwater aquarium fish species.
- However, guppies have been introduced to many different countries on all continents, except Antarctica.
- Sometimes this has occurred accidentally, but most often as a means of mosquito control, the hope being that the guppies would eat the mosquito larvae, slowing the spread of malaria world.

- If you've ever checked a pond for tadpoles and saw huge six-inch beasties, they were likely young American bullfrogs.
- Like all tadpoles, bullfrog tadpoles live in the water.
- They face many predators, including fish, snakes, and birds.
- As they grow, the torpedo-shaped tadpoles sprout legs and lose their tails.
- In two to four years, the tadpoles emerge from the water as fully-formed bullfrogs.

are colorful lizards known for their ability to change color, their long sticky tongue
and for their eyes.
eyes of chameleons allow 360˚ vision - can move independently of each
other, giving the chameleon the ability to see all round itself when seeking
prey, and binocular vision in front when it is preparing to strike with its
long, sticky tongue
- Chameleons five toes are zygodactylous so they can grasp branches just like our thumbs and
fingers can grasp objects.
- The chameleon's tail can
wrap around tree branches while climbing. For this reason, the chameleon's tail
cannot be broken off and regrown like those of many other lizards

- Several types of Palm-Pitvipers, including this one, are in danger of becoming extinct, mostly because their habitat is being destroyed.
- In fact, habitat destruction and hunting threaten well over half of the 157 species of Pitvipers worldwide.
- Yet although scientists consider them endangered, only about 12 species carry this official label, allowing protection by law.

- Brachychampsa had short teeth and a large mouth that packed more power than those of living gators.
- These oral characteristics suggest that Brachychampsa may have preyed on turtles, which were very common in the Creek area.
