Fish, birds, reptiles, dogs, and mammals are all similar in one way. they all have a backbone. ~ann :]
Large carnivores such as bobcats, cougars, coyotes and wolves will prey on raccoons. Raccoons will prey on small mammals such as mice and young rabbits, frogs, crayfish, snakes, lizards, nesting birds, etc.
Crayfish will actually attack fish. It is best to keep them separated.
All reptiles are diapsids. Mammals (like you and I) are, in contrast, synapsids. So in that respect all reptiles are alike. However, I would not say they were all alike. Snakes are reptiles but lack limbs. Alligators are also reptiles, as are lizards. Tuatara, gavials, amphisbaenids, and tortoises each represent one of the four main modern orders of reptiles. They share some characteristics--just as you and I do, but I would not say they were all alike.
A crayfish is a crustacean that has a similar appearance to the shrimp. When referring to a group of crayfish you simply call them by the same name.
Birds and mice are vertebrates, they have warm bodies, hearts, muscles, lungs, eyes (two each), 4 limbs, digestive systems (some like the same foods)...
They are different because crayfish have pincers but birds do not.
they both can go into a defensive mode
they both can go into a defensive mode
They have both fly alike
They use their shells
Sex
They are arthropods, so in that way yes, they are the same, but their environment is very different.
They both make noises.
Cause they can both fly
They're both animals.
I also have the same question.
