Yes, it seems that sharks are tetrapods. And yes, it is the most well-known case of this. But there are far more of us in the animal kingdom than we’d like to admit. We don’t feel like we are a separate species, or that we don’t belong in an ecosystem, if you will, where we’re just one among many species.
A shark is not a tetrapod, a tetrapod is not a shark, and a shark is not a tetrapod. Sharks are tetrapods because they have a tail, a tail which is used for swimming, and their fin can be used to capture food. Sharks are tetrapod because they use their tail as an armor, and their fin is used for defending themselves. But there are other examples of tetrapods that are not sharks.
This isn’t about the big picture, it’s about how we’re supposed to feel about the big picture. Because I’ve always wanted to write about evolution, I can’t really talk about it without looking at the larger picture. In the case of evolution, we’re supposed to feel that if we can’t think of a new way of doing things, we’re afraid, and we have no idea how to change our ways.
I know that’s a long way from a scientific paper, but what I mean by this is that my wife and I have always been really into sharks. When we were younger we would always go out and swim with sharks. As we got older we would spend a lot of time on the beach watching them swim. We would also spend a lot of time in the pool at the local golf course. We also always had a shark tank in our basement so we could watch sharks swim around.
Well, you can’t take it with you. Sharks are actually the second largest vertebrate reptile on the planet. They are also the second most venomous animals on the planet after snakes. One can only wish that we had a strong shark population in our area to protect us from these creatures.
Yeah, a shark could easily take a human in its mouth and eat them. And then they would have a nice big bite out of them.
We do. In our area, sharks and rays have been known to eat a small, often-drowned human, but these days many beachgoers are not so quick to leave their pets along the shore to die. After a shark or ray bites a swimmer, the shark or ray will often swim right up to the victim and let out a very loud “boo” or “oo”.
If a shark or ray doesn’t kill you, it will probably scare you away from your pet. And then you’ll be so traumatized and confused that you won’t be able to go to a beach again. It’s that bad.
The problem is when you’re a shark, you dont’ want to swim away from your pet, and there’s no way you’ll ever have to return it to its former life. We’re not even sure if youre a shark or a ray. We just know you are.
The fact is, sharks and rays are just like we are. We can easily become attached to our pets. Theyre as much our friends as our pets. When we see one of them swimming nearby, we can even be reminded of the moment in our lives when we first held that pet. We have a lot of memories attached to them, and some of them are probably very special.
