calcifying tooth crown

4 ever green presents 11 animals you won't believe actually exist 1.the blue angel "glaucus atlanticus"at first, people think its not a real creature.actually its a funny-looking animal that spends itslife floating upside-down on the surface of the pacific, atlantic, and indian ocean, andalso it seems just a harmless creature that likes to relax in the water. but this slender, up-to-3-centimeter-longanimal, which is called the blue glaucus, is not nearly as innocent as it seems. the first trick it’s got up its sleeve isa form of camouflage called countershading


that protects it from both flying and swimmingpredators while it floats.secondly it can swallow its prey’s stinging cells withouthurting itself.its prey is portuguese man-o’-war whose sting is very painful to humans 2.the desert lover "gobi jerboa"the gobi jerboa was discovered in 1925 by glover morrill allen. it is found in the gobi desert located innorthern china, as well as in southern mongolia, and is considered to be the most “desertloving” out of all gobi rodents .one of the most prominent features of the gobi jerboaare their ears, since they are almost three times as large as their heads.


their large ears give them an extra keen hearingsense, which helps to serve as extra protection in their vulnerable environment to cool theirbodies by dissipating heat. its long tail helps to accelerate bipedalgallop. 3.the deep sea "goblin shark"they feel comfortable living in the very deep parts of the water close to the floor of theocean. they don’t like to be exposed to the sunlightso they are sometimes referred to as vampire sharks. the numbers of them aren’t even able tobe estimated due to the lack of sightings of them.some persons who have seen them inthe water report disabled and disfigured sharks.


they assume this is some type of species thathas been born with genetic concerns.since goblin sharks live at the bottom of the water,they tend to feed on the organisms like sting rays, mollusks, and crabs which resides inthe same depth.they do feed quite frequently which is interesting. the goblin shark has a very large liver whichis usually found in sharks that don’t eat very often. 4.hummingbird hawk-moththe hummingbird hawk-moth is named for its straw like mouth and its hovering behavior,which, accompanied by an audible humming noise, give it remarkable resemblance to a hummingbirdas it visits flowers to feed on nectar.their


requirement for the carbohydrates they useto power their rapid and constant wing movement is so strong that they will continue to feedeven as they are mating.actually its a large sphingid moth found in warm climates in europe,north africa, and asia. it is a strong flier, dispersing widely inthe summer but it rarely survives the winter in northern latitudes. 5.the rare purple frogthis frog has a highly distinctive and somewhat comical appearance, with a hugely bloatedbody and short, stout limb.it has been found in western ghats of india.known from only135 individuals, of which only three are female, the purple frog is thought to be an extremelyrare species.


this species is threatened by ongoing forestloss for cultivation.pignosed frogs spend most of the year underground, coming out inthe surface only for about two weeks each year, to reproduce. this is why the species had gone unnoticedfor so long by biologists, until 2003 when it was officially described.mating occursduring the pre-monsoon rains, primarily in may. males use strange calls to attract females. 6.the boxer "mantis shrimp" .. thumbthe mantis shrimp is one of the most interesting crustaceans found in the ocean.


mantis shrimp are only about four inches longbut pound for pound are one of the strongest animals in the world. they use clubs that are more like elbows thanfists to punch their prey -- with the force of a bullet shot from a 22 caliber gun. this incredible force is important for huntingfood -- easily breaking the shells of prey like crabs and clams.when captured, scientistskeep mantis shrimp in strong plastic tanks because their punch could break a glass tank.butthey aren't just strong, they're fast too! they have the fastest predatory strike inthe ocean -- swinging in less than 800 microseconds. in the time it takes you to blink an eye,the mantis shrimp could theoretically punch


500 times. 7.irrawaddy dolphinthey have a flexible neck which accounts for the creases at the back of the head.interestingthing is these dolphins have a smiling face.i don't know why but they always smile .divingis very frequent for this dolphin species. every 70 to 150 seconds they have to comeup for air. often, it is only the head and perhaps thebody that is seen when they surface for air. it is very seldom that you will see the irrawaddydolphin with the tail out of the water.they are highly social but there may be from 3to 6 members per pod. they are very curious about their surroundingsand have been observed looking around when


they surface for air to see what is aroundthem. the irrawaddy dolphin has long and wide flippers. they can be from 70 inches to 108 inches long. they can weigh from 215 to 350 pounds.theyhave been found around the philippines and india. 8.japanese big spider crabsthe japanese spiders crab are known for having long, spindly legs. these are mostly limited to the pacific sideof the japanese islands.although not the heaviest, the japanese giant spider crab is the largestknown living arthropod.


the well-calcified carapace is only around37 centimeters long, but adult specimens can be nearly 4 meters long.these large crustaceansgenerally do not hunt, but instead crawl along and pick at dead and decaying matter alongthe sea bed. this includes both animal and plant matter. they occasionally eat living kelp and algae. although they move slowly, giant crabs occasionallyhunt for small marine invertebrates that they can catch easily.japanese spider crabs mostoften inhabit the sandy and rocky bottom of the continental shelf and slope at an averagedepth of 150 to 300 meters. 9.deadly lampreylampreys are some of the most primitive vertebrates


alive today, they are known as cyclostomes,which means 'round mouths' and refers to the fact that they are jawless, having insteada round sucker-like mouth.lampreys are fresh water, eel-shaped jawless fishes.many lampreysare parasites. they attach on other fishes by means of theirsucker, scrape their skin with their rasping tongue, and suck their blood.the sucker isalso for them a means to travel upstreams in rivers. they use it to attach on stones to rest .thesucker which surrounds the mouth is strengthened by a ring-shaped annular cartilage and bearsnumerous horny denticles which can rotate on the tip of a retractable piston cartilage.theyattach themselves so tightly that the victims


are not usually able to shake them off, despitethe suffering they incur from these parasitic fish. the wounds made by the lampreys can causedeath in the victims. 10.lowland streaked tenrecan extraordinary-looking family, the tenrecs exist only in madagascar.their normal lengthis 16 – 19 cm, and weighs around 90 – 220 grams. members of the subfamily tenrecinae look likea cross between a shrew and a hedgehog, with long, pointed snouts and spines amongst theirfur. it is blackish-brown with yellowish stripesrunning the length of the body and a yellowish


band running from the crown to the tip ofthe snout. it has detachable spines which are most numerouson the crown. the underside is chestnut-brown with softhairs.mothers and young communicate by vibrating specialized quills on their mid-dorsal regioncreating a low-pitched noise. these tenrecs also make ‘crunch’ and ‘putt-putt’sounds, particularly when agitated. 11.naked mole ratthe naked mole rats aren't totally naked, either. they have about a hundred hairs on their body,meant to help them with digging and navigating their tunnel system.they have sharp long teethbut do not have lips.


they live their entire lives underground;if it gets cold, they form a huddle and heat each other. each colony has a minimum of 20 individuals,though some colonies have as many as 300, and their territory may stretch for half amile. they're low in oxygen, smelly, and often crowded.actuallynaked mole rats eat their poop. that's because they also eat tubers — theirmain food source — which can be difficult to digest on the first pass. so once they've pooped out their food, theyjust... ingest it again. also, since the naked mole rats are nearlyblind, they identify themselves as part of


the colony by rolling around in the poop chambers. that way, everyone stinks exactly the same— and colony members can be easily identified.
