Scary Spider


A STARTLING EXPLORATION OF THE SPECTACULAR UNIVERSE THROUGH SCIENCE, HISTORY, ART, SPIRITUALITY AND MORE

reallymadscientist:

As a scientist, the movie poster for ‘Lucy’ is very painful:
1. There’s a defect in mismatch repair. Unless the secret to using more than 10% of our brain is to replace all guanines with adenines, or all thymines with cytosines. 
2. Also, I’m pretty sure neither of those nitrogenous bases actually exist. They sure as hell aren’t cytosine or adenine.
3. Oh yeah, the 10% thing. About that.
4. Nitrogen with 5 bonds?

FRILLED SHARK
Scientific Name….Chlamydoselachus Anguineus Family Name……  
General Information: The frilled shark or eel shark, has a long slender body with an elongated tail fin, which gives it an almost eel-like appearance and one of its common names. A single dorsal fin is located well back on its body, directly above the large anal fin. The pectoral fins are short and rounded. This shark has six pairs of large gill slits, where as most sharks have five, the first pair which joins under the throat. The gills are surrounded by frilly margins of skin, hence the common name frilled shark. Its snout is short while the head is snake-like, the lower jaw is long, with mouth almost at the tip of the snout rather than under the head.
Size: They can grow up to 6 to 7 feet in length.
Teeth: The frilled sharks teeth have broad bases with three sharp cusps separated by two small intermediate cusps. They are armed with about 300 teeth, set in 27 rows. Each tooth carries three sharp hooks, so prey stand little chance of escape.
 Color: They have a dark chocolate brown, brownish-gray or brownish-black body.
Feeding Habits: Little is known about its diet, but with such teeth, it probably feeds on small deep-water fishes and squid. They are known to swim with their mouth open to lure prey to conspicuous white teeth.
Social Behavior: They seem to segregate by size.
Habitat | Migration | Distribution: Frilled sharks are found in Eastern Atlantic, western Indian Ocean, western and eastern Pacific. It is found on the bottom shelves and upper slopes around continents and large islands. Occasionally, it is seen near the surface in open waters, but it usually lives at a depth of 330 to 4,260 feet, so the only chance of observing it is from a deep-water submersible. It is sometimes collected as by catch during bottom trawling.
Life Span: Unknown.
Reproduction: Frilled sharks are ovovivparous,( retaining thin shelled eggs within the mothers body) females bear 8-12 live young, per litter on huge uterine eggs. Pregnant females have very large abdomens. Gestation period is very long one to two years.
Frilled Shark Attacks: Harmless.
Population Report: Not uncommon.
Frilled Shark Facts: The frilled shark ( Chlamydoselachus anguineus ) is a primitive shark, the sole living member of the Chlamydoselachidae in the order Hexanchiformes. It is very different from the other hexanchiform sharks, and it has been recently proposed that the frilled shark should be given its own order. Chlamydoselachiformes.

This fearsome fossil is Ursus spelaeus, a cave bear that lived 14,000 years ago. 
Cave bears, although related to the largest living bears the Arctic, lived only in Europe. Cave finds in the Alps are evidence that the bears’ habitat extended up to altitudes of 6,300 feet. Most of the tens of thousands of remains found are of young and old animals that died during hibernation. Skull accumulations and depictions in cave paintings show that the Bears were important to ice age humans.
This fossil is located in the Hall of Advanced Mammals.

Stapelia hirsuta var. hirsuta
The beautiful and rare Stapelia hirsuta (Gentianales - Apocynaceae) is a species restricted to the South/western Cape Province of South Africa.
This bizarre plant produces a huge, star-shaped flower reaching 6” across. This species is covered in dense hairs. However, the unique aspect of these plants is that in wild they are pollinated by flies and beetles and emit a special, foul smelling odor.
The genus epithet “Stapelia" was named in honour of Johannes van Stapel, who published drawings and descriptions of the first Stapeliae discovered. The species name derives from the Latin adjective “hirsutus” meaning “rough, shaggy, bristly”, so the specific name implies: “hairy”.

This week’s creature feature is the Lord Howe Island stick insect, or phasmid. The species was down to just a single population of up to 40 individuals living on a single bush on the sea stack Ball’s Pyramid, just near Lord Howe Is. You can only get there by boat and rock climbing. Melbourne Zoo is working on a captive breeding program.http://ow.ly/ysyys
