Do you know stingray ,? probably not familiar stingray following is a glimpse of stingrays that you may not know. Stingray is one of the cartilaginous fish, alike shark. They entered the suborder Myliobatoidei of Myliobatiformes, they consist of eight families: Plesiobatidae (stingray water inside), Hexatrygonidae (stingray sixgill), Urotrygonidae (light round), Urolophidae (stingarees), Dasyatidae (stingray whiptail), Gymnuridae ( ray butterfly), Potamotrygonidae (stingray river), and Myliobatidae (eagle rays).

Stingray spines are venomous stings that one or more of the tail, is used for self-defense. Stinger length can reach about 35 cm, the bottom has two fangs like grooves with venom glands. Stinger covered with a thin layer of skin where the toxins are concentrated, some members do not have a sting ray.

Stingrays live in coastal marine waters of tropical and subtropical throughout the world, and there are also species found in warm temperate seas, such as Dasyatis thetidis, and is found in the deep sea, as Plesiobatis daviesi.

This now stingrays are not endangered, but in some species such as D. colarensis, Taeniura meyeni, D. garouaensis, and D. laosensis), conservation status makes them vulnerable or endangered in the IUCN.

Agency stingray and the average is very fortunate for them because they are easily able to hide themselves from the environment. They stir the sand and hide underneath.

Stingrays have eyes on top and while his mouth is on the underside, with this then stingrays can not see their prey, instead they use smell and electroreceptors (ampullae of Lorenzini) which is similar to a shark. Food stingray particularly mollusks, crustaceans, and small fish. At the mouth of a stingray, there are two strong canine.

Jellyfish are marine animals that ugly and dangerous, these animals are not also for eating. However there are a few species of jellyfish that looks very pretty and not the edits, this is a creation of god almighty. Want to know more clearly ?? Here are a few species of jellyfish are pretty and cool.

AEQUOREA VICTORIA

Jellyfish is known by the name AEQUOREA VICTORIA also called jellyfish crystal (crystal jellyfish). These jellyfish can be encountered on the west coast of North America. Jellyfish is physically colorless and transparent tentacles nematocysts that are used to catch prey. Nematocysts and also has been used in research and science because there is a protein called with GFP.

GFP soon is one of the proteins that can form a neon green color blue found on the body Aequorea Victoria. GFP was also used by the scientists to create a rabbit that glows in black light.

Australian Box Jellyfish

These jellyfish are most dangerous. Australian Box Jellyfish they have the shape of a cube, and also the jellyfish is not easy to see because his body is transparent and rapid movement. They goodness mutants and their eyeballs are on their stomachs. Australian Box Jellyfish are the most dangerous animal with nematocysts contained high concentrations. they can kill dozens of people, they also look very intimidating than other jellyfish in the world.

Bathykorus Bouilloni

This is one species of jellyfish that lives at the North Pole. jellyfish species was only discovered a few years ago and a lot of people know about this. they are many who call with Dart Vader. Jellyfish tentacles, there are four primary and four secondary tentacles. At each quadrant has 3 pockets manubrial interradial, is used to hold the toxic tentacles towards the front. This is one method for capturing prey.

Costa Rican Jellyfish

Costa Rican jellyfish Jellyfish have another designation Stauromedusae. Stauromedusae This is the term in accordance with the appearance of strange jellyfish have. Jellyfish body is trumpet-shaped, and is also unique from the jellyfish is that they have a change of phase polyp and medusa in its life cycle. In most species, sometimes directly and immediately developing into adults. Jellyfish can be encountered in Costa Rica that have very hot weather and with a depth of 8000 meters above sea level.

Flower Hat Jelly

From fourth on top of this jellyfish Flower Hat Jelly rarest ie, they are in the waters of Brazil, Argentina, and Japan, this jellyfish has a small size of about 6 inches.

Red-eared slider is also known as a turtle '' red-ear slider '' or in Latin '' Trachemys scripta elegans ''. This is due to the red color tinge right behind his eyes that resemble red ear. Red-eared slider comes from the southern United States, has a shell color mixture of green and yellow. Durability Red-eared slider turtle makes strong adaptable to any environment. Age turtles can reach the age of 20 years with a maximum length of about 30 cm. Red-eared slider breed by laying eggs. The amount varies between 20 and 45 grains depending on the fertility and weather. Red-eared sliders are usually laying around August to September before the rainy season. and for hatching takes about 3 weeks. After hatching Red-eared slider will soon find the water to grow up. Red-eared slider dark green with yellow stripes and have a red spot on each side of his head. These turtles can be easily distinguished by the lower jaw is more rounded than the type pseudemys more boxes. Hind toes are connected by a membrane like a duck because they are aquatic animals. to distinguish the sexes, males have longer claws on the front legs. while at the female cloaca closer to the shell than males.

Because Red-eared sliders are aquatic animals, therefore we need to put in the aquarium or pond that is comfortable and designed specifically to meet their needs. if we do not want to provide an outside, the aquarium is the best solution for the Red-eared slider. in addition, by using the aquarium, we could be easier to clean. Red-eared sliders are aquatic animals and they dispose of their waste into the water, so if we do not maintain a healthy aquarium or pond then it will become a hotbed for germs and bacteria, to the aquarium and pond should always be clean for the health of turtles hanging from the cleanliness of the aquarium or pond. if not using the filter, clean it every other day. for baby turtles, cleaned every day and do not use products that abresif. For aquarium size can be adjusted to the size and number of turtles owned. aquariumnya the bigger, the better for turtles, because the turtles are growing very fast in the first years. And the recommended water is about 3/4 of the length of the turtle. Of most turtle keepers recommend to use the filter tube 403. Fluval as Red-eared sliders are cold-blooded animals, so we have to keep the temperature stable between 20 ° C to 28 ° C by using the '' submersible heater '' or heating water in the form of a long tube containing coated wire. in addition, we need to provide a basking area for turtles, where turtles can be completely dry basking in sunlight or a special lamp reptiles, because in the wild, turtles will spend the time to bask under the sun. this is very important, because warmer temperatures can increase the body's immune turtles, and Red-eared slider requires UV light to be able to process food properly and absorb nutrients from food. to add a decoration on a pond or aquarium should be careful. for example, want to add rocks, must choose the type of rock that is not sharp because of sharp rocks can injure tortoise shell. then the addition of sand or plastic plant is not recommended, because there is a possibility turtles will eat and can cause serious intestinal complications.

Blobfish is a deep sea fish of the family Psychrolutidae. Inhabits the deep waters off the coast of mainland Australia and Tasmania, these fish are rarely seen by humans.

These fish live in the ocean depths where the pressure is several dozen times higher than at sea level, which is likely to make the gas bladder is not efficient to maintain buoyancy. Instead, the meat of this fish has a density that is lighter than water, it allows the fish to float above the sea floor without expending energy to swim. The relative lack of muscle in the fish is not something detrimental because Blobfish can eat anything floating in front of him. Blobfish eat invertebrates such as crabs and sea pens.

Blobfish is currently facing extinction because of fishing in the sea or because trawl. According to the National Oceanic and Atmospheric Institute USA, blobfish described as large-bodied fish like tadpoles, supple skin like jelly, a big nose, and had a big black eye.

If considered more carefully, blobfish face looks like the face of someone who gloomy and sad. Mucus out of her face even looks like a tear dripping. Blobfish body in general have an average length of 12 inches. The main food of these fish are crabs and lobster.

Blobfish can be found in the waters of southeast Australia and Tasmania at depths of 2,000 to 4,000 feet below the sea. Blobfish was selected as the worst animal after winning the online voting held by Ugly Animal Preservation Society on the website YouTube. The purpose of voting is to show the world community that there is still a lot of biodiversity in the world.

Blobfish threatened with extinction as a result of the action of fishing on a large scale. Although not edible, Blobfish live in water depths similar to other marine organisms that can be consumed, such as crab and lobster.

Thanks to fishing techniques that do not harm endangered species, the scientists managed to capture Blobfish for later study.

Weasel Water - This is a semi-aquatic weasels are found in primary forests can be found in lowland forests. These animals can be found in the area -sungai rivers and swamps. Thailand to the Malay Peninsula, Borneo to Sumatra. This last species of otter civet is considered as a separate otter civet usually called the civet Lowe (Lowe's Otter, C. lowei).

Weasel water or in Latin known as Cynogale bennettii, they have a shape that is adapted to their environment or habitat, water weasels have wide mouths and their feet webbed with pedestal bare feet and has a long claws. His snout is long and has a long mustache, they have a body size similar to a beaver. they weigh up to 3-5 kg ​​adult.

The civet is a nocturnal animal that constitute activity animals at night, they were looking for food in water like fish, crabs, animals and other small water. In addition to consuming animal animals in the water is also able to climb trees and they eat birds and sometimes fruits. Activity in the evenings and they often hide the animals is not much learned.

Otter civet though its population is less in the know, but ferrets are included in the endangered animals in Indonesia and the world, estimated a decline in the habitat of these animals samapai 50%. This is due to the occurrence of forest loss due to its pengundulan and polluted water, and the destruction of river areas where they find food.

Although this animal is an animal that is rare and they are protected in the world, but most people consider it a pest, who stole and ate fish in ponds of fish pet society. These animals are also sometimes made as a pet because of its beauty and agility and also most successful breeding by way of good care.

Hundreds of toxins

There are about 500-600 species of cone snails. Everything is toxic. Well, the cone snail can have about 200 types of toxins. So, imagine if all kinds of toxins from cone snail species put together. Thus, it can be collected tens of thousands of types of poison!

The most toxic

Among the species of cone snails, one of the most toxic. He is the geographic cone snail. Conus geographus scientific name. Oops preferably, do not go near the geographic cone snail is, deh!

Toxic harpoon

Cone snail venom lies in organ-like harpoons. The harpoon fishing gear like a shot arrow. Well, when it was ready to attack its prey, venomous cone snails harpoon issuing from his mouth. Install a blink of the helpless, and the direct cone snails devoured round!

Human victims

Cone snail venom is not only deadly to animals, such as fish. Toxins that also claimed the lives of humans. There are already dozens of human casualties as a result of toxins that are super dangerous. Until now, there has been no cone snail venom antidote!

Used as medicine

Although deadly, cone snail venom turns out useful to humans. The venom contains proteins that can be used as painkillers. Painkillers from poison it 10,000 times more potent than the painkillers of chemicals.

When a fisherman pull coelacanth out of the sea in 1938, the researchers were surprised. Very flaky fish with a lobe that is leftover from the past, a time when dinosaurs roamed the earth. Scientists have coelacanth fossils that are hundreds of millions of years, and today it is believed that they all had died in the same incident that killed the dinosaurs.

But it turns out some of the coelacanth survive, and scientists have been studying these strange fish for decades. We know that these fish have peculiarities, hinged jaw, stay off the southeastern coast of Africa and in Indonesia, and eat squid and octopus. What we do not know is that this fish was also to have lungs.

In a study published yesterday in Nature Communications, the researchers found that, like its predecessor, namely their fossils, modern coelacanth also have a structure such as the lungs. Lungs are present in the embryo, but stop developing when the fish grow, so it is difficult to see unless you know what you are looking for (and you have access to a high-powered X-rays).

Scientists know that the fossil coelacanth has this strange organ but this time they thought the lungs was gone as species change over the years. Although coelacanth have lungs, it does not mean they can breathe with it. The authors found that the lungs of non-functional stretcher, or the rest of the organ.

Typically, the fish do not have lungs, they use gills instead. One of the few exceptions is the lungfish, which can modify their bladder (usually used for buoyancy) into organs of respiration

The researchers believe that the presence of the lung may indicate that the coelacanth ancestors may have lived in shallow waters with low oxygen levels, as opposed to the environment they prefer at the moment, namely the deep sea.

Blowfish is one fish that is funny and cute because of when they were inflated, the fish is known by the name Blowfish, and this is a fish that is included in the dangerous fish, these fish are dangerous because when inflated are thorns are poisonous.

Blowfish is entered in carnivorous animals in its meaning is one of the carnivores. These fish can be encountered in the Indian Ocean, Pacific and Atlantic. Blowfish they have sharp teeth and fused is used to destroy its prey. These fish prey on shrimp, sea urchins, algae, crabs and shellfish.

This fish is actually not again swim, and they are also known as puffer fish, many threats to them. they survive by inflating himself by putting water into the body so can not eat the other fish, when inflating yourself these fish can size 2 to 3 times that of body size is normal, when they inflating themselves the thorns the body appeared and hardened. So with this they survive from predators.
