Real Life Sea Monsters - 24 Bizarre Creatures of the Deep : Who Sucks
Harriet the Giant Galapagos Land Turtle celebrated her 175th birthday yesterday at an Australia Zoo. Harriet was collected by Charles Darwin in the year 1835, and is recorded as the worlds oldest living animal.
Wouldn't it be great to see her live, and maybe ride on her back !?
- meaning , si charles darwin diay tag-iya ani na turtle ,. the person who claimed evolution .. hehe nondota oi.
na baya alaga si kuya kim ani...
The Only Immortal Animal on Earth
Turritopsis nutricula

Have you ever wondered what would happen if our life cycles were reversed, that is if we were born old and died young? Well, there’s one animal that comes close and has achieved immortality in the process, just to top it off. Meet the Turritopsis nutricula, a small saltwater animal or hydrozoan related to jellyfish and corals.
Like most jellyfish, Turritopsis nutricula undergoes two distinct stages in its life cycle: The polypoid or immature stage, when it’s just a small stalk with feeding tentacles; and the medusa or mature stage when the only 1mm-long polyps asexually produce jellyfish.
Turritopsis nutricula in its aptly named medusa form with a bright red stomach:

A jellyfish’s lifespan usually ranges from somewhere between a few hours for the smallest species to several months and rarely to a few years for the bigger species. How does the only 4-5 mm long Turritopsis nutricula (let’s call it T’nut) manage to beat the system?
Well, T’nut is able to transform between medusa and polyp stage, thereby reverting back from mature to immature stage and escaping death. The cell process is called transdifferentiation, when non-stem cells either transform into a different type of cell or when an already differentiated or specialised stem cell creates cells outside this specialised path.
The polyp state of Turritopsis rubra, long synonymised with T’nut:

T’nut requires tissue from both the jellyfish bell surface and the circulatory canal system for its transdifferentiation. This switching of cell roles is not unusual and can be seen in many animals and humans, but usually only when parts of an organ regenerate. In T’nut’s case, reverting back to an immature state is part of its regular life cycle.
In its medusa form, Turritopsis nutricula is bell-shaped and about 4-5 mm in diameter. Young specimens will be only 1 mm in diameter and have eight tentacles to start out with but can have between 80 and 90 as adults.

Turritopsis nutricula most likely originated in the Caribbean but can now be found in the temperate to tropical regions in all of the world’s oceans, spreading further through the ballast water that ships discard in ports. According to Dr. Maria Pia Miglietta from the Smithsonian Tropical Marine Institute: “We are looking at a worldwide silent invasion.”

Silent invasion? Possibly, but while Turritopsis nutriculae may be biologically immortal, they are surely not invincible. Especially in their immature stage, they are susceptible to predators and diseases and many die before they even reach jellyfish stage. Still, they are to date the only known animal capable of reverting to an earlier, immature stage.

dahan imba jud, hehehehe
I think naka dungog or nkketa mug "tamed" lion ug grey wolf ryt? pero actually, they are not as tame as a house dog or cat, meaning k2 circus or zoo animals na claimed as tame kay dili ma sure ang iyang temper, maybe docile lang pero not tamed..
however, para nko, ang PINAKA tamed na lion ug grey wolf kai kani cla, watch it, hope u guys enjoy!

YouTube - Christian the lion
kani cla kai super tamed jud kana bang wa ka nag expect na ang love na imung gehatag aning mga wild animals kai gebalik nimu 100000x ~ hahaist..... ganahan kog grey wolf hehehe jwk~
yah, very well said...
a different kind of extinct humans ..
YouTube - Neanderthal - Episode 1 - Part 1 of 5
Neanderthals had long, low, thick-boned skulls, with heavy brow ridges, in contrast to the high-domed, thin-walled skulls of modern human beings. The robust, heavily muscled frames of Neanderthals, with relatively long bodies and short legs, were well adapted to their hunter-gatherer lifestyle in the often extremely cold conditions leading up to the last Ice Age. Although males were more strongly built than females, both sexes were very muscular, even as children. Neanderthals had large heads with very large projecting noses and receding chins. On average their brains were as large or larger than the average modern human brain, which was probably related more to their large body size and heavy musculature, than heightened intelligence.
macho man au ang females LOL
