Looking At The Skull Where Are They Eyes Positions

1.) Looking at the skull, where are they eyes positions (front, side, top)? How much of the skull is taken up by the eyes? Does this suggest anything about how/when they live/get food?

Pigeon: The position of the bird’s eyes are on the side of it’s head. The eye sockets are also very large taking up roughly one third of the entire skull leading us to assume that vision was a key sense for the pigeon.

Bat: the eyes are positioned on on the top of the head and take up a small portion of the skull. Although bats are blind, the placement and size of their eyes suggest that they once needed eyes to capture prey.

Snake: the eyes are positioned on the top of the head and take up a large portion of the skull. This suggests that they are heavily
Although cats are domesticated, this suggests that they need larger eyes in order to spot prey from far distances and to have the ability to see well in the dark.

Frog: the eyes are positioned on the top/side of the skull and take up a large portion of the skull. Their eyes are set very far apart suggests that they use their eyes to see in front, to the side, and behind them without having to turn their heads. This allows them to spot predators and prey without movement.

Perch: the eyes are positioned on the sides of the skull, it takes up about ¼ of the skull. This suggests that they don’t depend on their eyes as much to detect prey and that their vision is not that good.

Mink: The eyes are positioned on the front/side of the skull and take up about half of the skull size. This suggests that they use their eyes to spot prey easily, because their eyes have good visibility, and need to be able to see while in the water searching for prey.

2.) Look at the jaw and teeth if present. Does the organism have teeth? Are they all the same shape? Are the largest teeth on the upper or lower jaw? What does the size, shape, and arrangement of the teeth suggest about their diet? (it may be helpful to look at the separate bobcat, goat, and raccoon skulls that we
The largest teether are on the upper jaw. The two large front teeth helps them puncture the artery and skin in their prey.

Snake: Yes, and they have very small teeth lining both the top and bottom of the inner jaw. All of the teeth are a smilier shape and size, although the bottom teeth are slightly bigger. The size and shape of their teeth suggests that they may not use them to bite or chew on their prey.

Cat: Cats have evolved from carnivorous predators which means that they use their assorted sets of teeth to grind and rip food when it is eating its former diet of small animals. The mouth of the cat takes up a large portion of their skull considering it is one of their key features for survival, being used for eating, cleaning it’s body and many other uses. The cat has two large teeth in the front of their bodies which we assume is for puncturing its prey.

Perch: Yes the perch has teeth. They have multiple layers of teeth text extend throughout the bottom of the jaw. They’re not all the same shape, the ones in the first layer are longer and have pointy ends, and as the layers proceed backwards, the size decreases. This suggests that the perch uses its teeth to catch prey, grip them in their mouth and to trap them
