What are the major mammalian characteristics exhibited by a fetal pig?

During dissection, it is possible to observe more of the mammalian characteristics of the fetal pig. Female fetal pigs have mammary glands connected to their nipples for nourishing their young.

What are the adaptations of the king cobra?

Like all snakes, king cobras are able to sense vibrations through their jaw bones and can smell and taste the air with their tongues. However, they have better eyesight than many other snakes, with an ability to see up to 330 feet. In addition to being fast, king cobras can raise more than one-third of their body off the ground to warn off predators.

How do insects protect themselves?

North Carolina State University explains that when a predator grabs a leg of some insect species, such as crane flies, the insect can break off the appendage. Called autotomy, this technique is also employed by walking sticks, grasshoppers and other long-legged species. Some insects regenerate their lost limbs, but even among those that don't, the missing appendage usually isn't a serious burden.\nOther species, particularly a number of caterpillars, use bristles, spines or hairs to defend themselves. Some of these hairs dissuade predators through mechanical means. Contrastingly, oth..

What do you feed lizards?

Most small species, including geckos, anoles and chameleons, are completely insectivorous, although a few geckos lap baby food or soft fruit.

Iguanas are primarily herbivorous and should be fed an assortment of fruits and vegetables. In contrast, monitor ..

Most anglerfish are so big and their bodies so flexible that they can swallow prey up to twice their size. Their mouths are lined with sharp, translucent teeth that are angled inwards to prevent prey from escaping, as finding food at the depths in which most species live can be challenging. Some members of the species can grow to sizes of over three meters in length and weigh over 100 pounds.\nMales of the species have no need for the lighted lure that females have because of the unique way in which they reproduce. Instead of finding food, a male anglerfish, which is significantly smaller than..

Are sand crabs edible?

Sand crabs are often used by fisherman as bait to help catch pompano, red drum and even kingfish. Special rakes can be purchased to help dig these little crabs out of the sand, where they tend to hide while waiting for bits of food to float by. These crabs are the smallest in size of all crabs and they can sometimes be found in large numbers around stinging jellyfish. These tiny crabs eat bits of tentacle by wrapping the tentacle around one leg and begin nibbling, so it is not recommended to eat sand crab in an area where there are lots of jellyfish.
