Interesting and Bizarre Predatory Animal Defenses

Evolution in the animal kingdom has caused species to partake in an armed race, which ultimately causes their adaptive traits to change over time within their gene pool. This trait may have been caused as a side affect of another adaptive mechanism or the dominate trait took over the adapted to protect the animal.

In many cases, a new defense can hinder an animals behavior or a relationship between a predator and it’s prey can change which then presents another problem for the weaker of the animals.

If the species cannot adapt to the environment with their new trait, they will go extinct, therefore allowing the species with that new trait that are adaptable to inhabit the pool.

This idea of Natural selection is one of the cornerstones of modern biology and was introduced by Charles Darwin in his 1859 groundbreaking book “Origin of the Species”. This book  explained the process by which the desirable traits of animals and plants are favored by the environment.

Peppered Moth

The peppered moth comes in  two forms, both white and molted. Before the industrial Revolution, they were commonly found with just a white coloration, however due to the pollution in the factories the molted coloration became for common. In all actuality, the molted trait allowed this species to blend with the environment, therefore this camouflage became the dominant trade.

Hammerhead sharks, amongst many other species of shark, are darker colored on their dorsal side and lighter on their ventral. This coloration allows them to blend with the colors of the sea, as well as warding off predators from below. Also, the head is mostly used to make swift turns while looking for food, therefore the movements and placements of the eyesockets are not a predatory defense. However, there are electroreceptory sensory pores called ampullae embedded throughout the body which allows them to detect prey by a type of sonar.

    Fascinating article Lauren! Found the Peppered Moth story really interesting in that is has basically evolved to live with man’s pollution.

    “but some of these animals are not predatory. ”

    The animals mentioned use these defenses against predators which is the basis of the piece. These are not predators, these are the animals that act on the attack.

    I’m afraid we will lose many of our insects and animals. I’m especially worried about bees. i have seen very few the last couple of years and in some places people are doing their own pollination. If that happens there will be world wide hunger.

    Great piece as usual Lauren.I had no idea the butterfly could do that. I’d never heard of that bird whose habitat is mostly snowy.

    Crazy facts Lauren. Had heard of some of the ways that animals trick their attackers into thinking they are something else but for me the snake omitting an odor was a totally new piece of info.

    Thanks

    Ummmm, shouldn’t the caption on the Hammerhead shark have something to do with the shape of its head, rather than coloration which is standard to most sharks?

    Chris that was typo. The head is mostly used to make swift turns while looking for food, not really a predatory defense.

    The electroreceptory sensory pores called ampullae allows them to detect prey by a type of sonar, which are not just found with the head.

    Their bodies are also sensitive to pressure changes, which allows them to detect prey as well.

    These critters give me the jitters – your animal stories always transfix me – except when they are real to the touch; then I’m scared.

    Thank-you, another brilliant peice . j
