There you can put in your hardiness zone 7, plant type (shrub, tree, groundcover, etc), type of soil, flower color, leaf color, deer resistance, height/width, water needs, and many other characteristics you may desire in a plant.
One of the most interesting differences between crocodiles and alligators is salt glands. Crocodiles tend to have functioning salt glands on their tongues which are only nearly visible while the creatures are basking in the sun on land with their mouths wide open.
Tooth type. Again, due to their usual prey types, crocs and sharks have very different types of teeth. A crocodile's prey is typically not only larger than a shark's but also have much stronger bones and skins. A croc's teeth therefore not only needs to be able to tear flesh off the wildebeest through death spin, but also needs to be strong enough to crush the thick leg bones of these mammals.
