Yes. However there are two families Heteropneustes and Clariidae that have bladders that act in a lung like way in addition to gills. There are zillions of species of cat fish and scientists are still changing the lists around.
Generally, catfish do have a bone structure, although it may vary depending on the species of catfish.
No, catfish do not have a set of teeth like other animals do. However, they do have a strong pair of jaws!
Most do they are just toothless and have sandpaper like lips allowing them to grasp food. There are some exceptions such as sucker fish but they still have a upper jaw.
Yes, catfish are vertebrates and have bones.
Yes they do. They just have a "horn" coming out of it for strength and protection and many people mistake that as not having fins.
A catfish does not have any thumbs at all, let alone opposable thumbs. Fish do not have limbs from which they grow fingers or thumbs; they have fins.
I Think So I Might Be Wrong
No.
no
Humans (with opposable thumbs) can grasp, carry and grip things that other animals including primates (who lack opposable thumbs) cannot.
The chimpanzee does have thumbs. But they are not opposable.
Opposable thumbs are use to holding on and pick up small objects. The macaques use their opposable thumbs to hold the tool to use it. Without opposable thumbs it could be hard or nearly impossible to use a tool to get food.
Bears do have opposable thumbs. Some bears have a special bone found in their wrists. Its their sixth toe and it is an opposable thumb. It is used for grasping bamboo. They use this bone in the same way humans use their thumbs, mainly for grasping food. Most species do not have opposable thumbs.
No besides us apes are the only ones who have opposable thumbs but ours are better
No, raccoons do not have opposable thumbs.
No, They Don't have an opposable thumb But a chimpanzee does!
No, mice do not have opposable thumbs. They have paws with a pollex, which is the innermost digit of the forelimb.
No. Unlike primates, most marsupials do not have opposable thumbs. The exception to this is the koala, which is a marsupial (not a bear). Both their front and rear feet can grasp things using opposable thumbs. The opossum of North America, also a marsupial, has opposable thumbs.
Yes they do, their thumbs are just so high up that they cant use them.
