The Tiny Killifish






Hello again today I will be talking about the amazingly tiny Killifish. There are 1270 different types of Killifish the biggest family is the Rivulidea family which has more than 320 species. The name Killifish is from the Ductch word "Kilde" meaning small creek or puddle. Most Killifish are small up to 1 to 2 inches long. The largest is under 6 inches. Striped Killifish live on a range of 10 months to a year and a half. Killifish are food to wading birds, aerial birds, and some ducks.


Killifish are mainly found in the Americas in freshwater or brackish waters. The majority of Killifish are found in permanent streams rivers and lakes. Killifish mainly feed on mosquito larva, insects, aquatic crustaceans, and worms.

The Musical Cicada















Hello again are you hearing a musical chirping noise outside if you are you are listening to a musical sounds of the cicada. There are about 2,500 speices of cicadas around the world. Cicadas are not considered pests nor do they bite, sting, or harm humans. The largest cicadas are in the genera Pomponia and Tacua.






There are some 200 species in 38 genera in Australia, about 450 in Africa, about 100 in the Palaearctic and exactly one species in England, the New Forest cicada, Melampsalta Montana, widely distributed throughout Europe. There are about 150 species in South Africa. The adult insect, sometimes called an imago, is usually 1 to 2 inches long, although some tropical species can reach 15 cm.Male cicadas have loud noisemakers called "timbals" on the sides of the abdominal base. Their "singing" is not the stridulation (where two structures are rubbed against one another) of many other familiar sound-producing insects like crickets: the timbals are regions of the exoskeleton that are modified to form a complex membrane with thin, membranous portions and thickened "ribs". Contracting the internal timbal muscles produces a clicking sound as the timbals buckle inwards. As these muscles relax, the timbals return to their original position producing another click. The interior of the male abdomen is substantially hollow to amplify the resonance of the sound. A cicada rapidly vibrates these membranes, and enlarged chambers derived from the tracheae make its body serve as a resonance chamber, greatly amplifying the sound. They modulate their noise by wiggling their abdomens toward and away from the tree that they are on. Additionally, each species has its own distinctive song.When the eggs hatch, the newborn nymphs drop to the ground, where they burrow. Most cicadas go through a life cycle that lasts from two to five years. Some species have much longer life cycles, the Magi cicada goes through a 17- or occasionally 13-year life cycle. These long life cycles are an adaptation to predators such as the cicada killer wasp and praying mantis, as a predator could not regularly fall into synchrony with the cicadas. Both 13 and 17 are prime numbers, so while a cicada with a 15-year life cycle could be preyed upon by a predator with a three- or five-year life cycle, the 13- and 17-year cycles allow them to stop the predators falling into step.






The insects spend most of the time that they are underground as nymphs at depths ranging from about 30 cm up to 2.5 m. The nymphs feed on root juice and have strong front legs for digging.

The Carnivorous Piranha






Welcome back today I am talking about the deadly Piranha! Piranhas are Omnivores (an animal that eats both meat and vegetation). Piranhas are mainly well known for there very sharp teeth.


You don't have to be scared Hollywood falsely accused the Piranha for being deadly and vicious. The Piranha are actually known to be even tamed to be pets in offices and homes. Piranhas are only found in the Amazon basin.


Normally Piranhas are 6 to 10 inches long. But some have been caught that are 16 inches long. Piranhas have a row of sharp teeth on both jaws. The teeth are tightly packed and made for rapid puncture and shearing.

(Not Arowana But)...Arapaima




Good morning today I will be talking to you about the Arapaima! It is found in south America and it is the LARGEST tropical freshwater fish in the world. The Arapaima is found in the Amazon river. They can grow up to 9.8 feet and weigh up to 440 lbs.



There diet consists mainly on fish and other small animals including birds. In South America the tongue is thought to have medical qualities. Sadly the Arapiama is hunted greatly by local fisherman.

The Arowana




Hello again its been quite awhile but I'm back. Today I will be talking about the Asian Arowana a golden fish. Arowanas are freshwater bony fish they are from the Osteoglossidae also sometimes know as "bony tongues". They got this name due to a toothed bone on the bottom of the mouth. In the Osteoglossidae family of fish the head is bony and the body is covered in heavy scales. The Arowana is an "obligatory air breather".




The Arowana is a carnivorous fish and are often specialized as surface feeders. They are excellent jumpers, jumping up to 6 feet and catching small birds and low flying bats. In South America they are called "water monkeys" because they jump up from the water and catch unsuspecting birds and insects on branches overhead. The Arowana can grow up to 3 or 4 feet but this was only measured in captivity.




In China the dragon is a symbol of good luck and prosperity. So they are used for feng shui to bring good luck and wealth.

Animal Of The Day- Liger


Welcome back. Today on The Hang Out, The Animal Of The Day is the Liger. The Liger is a mixture of a lion and a tiger. It is the cross between a male lion and a female tiger. A liger looks like a lion with faded stripes. A similar species is the Tigon which is the cross between a female lion and male tiger. Ligers enjoy swimming, just as Tigers. Ligers have a tiger-like striping pattern on a lion-like tawny background. In addition they may inherit rose like markings from the lion parent (lion cubs are rosetted and some adults retain faint markings). These markings may be black, dark brown or sandy. The background color may be correspondingly tawny, sandy or golden. In common with tigers, their underparts are pale. The actual pattern and color depends on which subspecies the parents were and on the way in which the genes interact in the offspring.There is no scientific name assigned to this animal because of it’s human assisted ancestry.On a typical day a Liger will devour 20lb of meat, usually beef or chicken, and is capable of eating 100lb at a single setting. A male liger may have a leonine mane, but this is much more modest than on the lion and many male ligers have little or no main at all.

Animal Of The Day-Hedgehog

Hello and welcome back to The Hang Out. Today is another Animal Of The Day and today's animal is the cute, yet not easy to pet, Hedgehog! The Hedgehog is a spiny little animal with about 3,000 to 6,000 spines on it's back. It has a furry belly that is one of the only places that you can pet. There are 16 species of hedgehogs. Hedgehogs are nocturnal creatures, and they hibernate during the winter in cold locations. They burrow in a small whole on the ground until the winter is over. The Hedgehog mother can be pregnant for about four weeks. Hedgehogs can have 4-7 babies. They make their nest out of dried leaves and grass. Their diet is worms, snails, slugs, beetles, eggs, bees, wasps, and sometimes even poisonous snakes. They have an immunity to the toxins so that they can eat wasps, bees, and poisonous snakes but they can not take a direct bite from a poisonous snake. When endangered the Hedgehog curls up into a ball and points it's spines upward. They live in Europe, Asia, Africa, and they where imported to North America. It is common to find an albino hedgehog. The albinos spines are white and it's eyes are pink.

Animal Of The Day-Portuguese Man-Of-War

Hello again, I will be listing pictures of animals and their description every day. Today I'm showing you a picture of a jellyfish called the Portuguese Man-Of-War. It is a beautiful animal, yet it is extremely dangerous. It's stings are very painful. The Man-o'-War eats small fish that swim near its stingers. The fish is almost instantly paralyzed and that's when the jellyfish uses it's stingers to bring the fish to it's mouth. The stingers, even when broken off the jellyfish, can submit a powerful sting that can kill small children and the elderly. It is also sometimes called the blue bottle because, well it looks like a floating blue bottle. It's body is about 3 to 12 inches long (9-30cm.) The Portuguese Man-of-War floats by the sack that actually emits its own gas. These jellyfish are found in warm waters in the Atlantic ocean. Well that concludes my first ever Animal Of The, Day so come back soon.
