Have you ever realized that there are actually some animals without tails? The animal kingdom is big and huge so it is understandable that it has different kinds of variants and species. Most of the animals do have tails but there are some that don’t.
We may not perceive anything different from them, but don’t you ever wonder why these animals don’t have tails and whether the condition is hereditary (genetics) or resulted from accidents?
Anury or Tailessness
The condition where animals without tails can exist is called anury. The reason can be various. It can be genetics, accidents, or even surgery. Exposure to toxic materials or substances is also possible. Besides anury, there is the so-called brachyury.
It is a condition where the animals actually have tails but they are very short when compared to the regular and typical one. These two conditions can affect any animal in the kingdom – no matter what species or genus they are.
So, what are the animals without tails? The first one is the toad. Toads are included in amphibians, like frogs. Unlike frogs, toads have parotoid glands (which produce toxic substance secretion whose function is to protect them from predators and killers), dry skin, and crests behind their eyes.
The tox substance is called bufotoxin and it can affect people and other animals. It can cause allergies for human and death in small animals. Toads protect themselves by blending in with their surrounding environment, especially if they have a green or brown color.
They can also puff themselves to look bigger whenever predators are close. If they have vibrant and bold colors, they will send out signals that they are dangerous and poisonous – so predators won’t be interested in coming near.
The second one is the frogs. Amphibians are taken from a Greek word, meaning both lives. It refers to the two world frogs are having – born and develop in water and then have a life on land (as well as on water).
Some frogs can be born as complete frogs – they don’t undergo stages of tadpoles or such thing alike. For these kinds of frogs, they can live far away from water, like on the mountaintops.
The Tailless Animals from Primate and Ape Family
Another animal is the gorilla. Yes, this burly, huge, and strong species is tailless. You can see them at the zoo or during the safari – and all of them will be tailless. Gorillas are included in the Hominidae family, which is basically a mammal.
This great ape is different from the other types of apes in the way they walk (they can walk upright for a longer time), they have more developed and bigger brains, they don’t have tails, and they are definitely physically bigger. Gorillas share similarities with primates – their arms are longer than the legs.
They can walk on 4 legs or arms – this movement is called knuckle strolling. Silverbacks are the call given to adult males because they have distinctive and unique silver hair on their backs.
Still in the same primate family, you have the chimpanzee. If you compare chimpanzee with other primates, you can see the distinctive difference in the tails. Since chimpanzee is a primate, they consume seeds, nuts, insects, and fruits. They can also consume meat occasionally.
The Spiders and Wasp
The list of animals without tails is still going on. Spider, for instance, is a perfect example of the tailless animal. You have to admit that spiders can be both interesting and scary – it may be not your favorite animal around. Spiders have eight legs and they are arthropods.
They can produce webs (thanks to the special glands to produce silk) that are used to trap other animals for food. Most spiders would live on land although some of them may live in water too.
It’s not exactly a big pool of water – just a small body of water. Spiders are quite resilient and tough because they can live (and survive) in various different environments.
Another tailless animal is the wasps. Wasps are often confused with the bees because they look almost alike. However, they are quite different in physical appearance, if you look closer.
Wasps have slim waistlines and bodies – and their body is somewhat glossier when compared to the bees. For now, there are around 100,000 varieties of wasps in the world.
The Marine Animal
The next one is an animal that is often thought to be plant – the anemones. This is actually a predator invertebrate that lives underwater and it has no bones. They look like blossom plant – which results in the misconception and misunderstanding.
Also known as the sea polyp, the anemones like to stay and attach with solid things in the sea or ocean. They simply wait until marine life goes by – and they can catch it with the tentacles. Since the arms are equipped with stingers, which can produce toxins, any marine life caught will be eaten right away.
What do you think about these animals? Knowing that they exist is pretty fascinating – not to mention that you can also learn new things about these animals without tails.
