The Giant Huntsman Spider (heteropoda maxima)

Giant huntsman spider is considered the world's largest spider.


Appeareance


The coloration is yellowish-brown with several irregularly distributed dark spots on the rear half. The legs have wide dark bands before the first bend. Like all huntsman spiders, the legs of the giant huntsman spider are long compared to the body, and twist forward in a crab-like fashion. Apart from its size, it can be distinguished from other species of Heteropoda by genital characteristics: On males, the cymbium is much longer than usual, at least three times longer than the tegulum. The female is distinguished by a characteristically shaped epigyneal field with two anterior directed bands, and the course of their internal ducts.
The giant huntsman spider is the largest member of the Sparassidae, boasting a 30 centimeter (12 inch) leg-span, and 4.6 centimeter body-length.

What Do They Eat? Can They Eat Me?! What About My Pets?

Huntsman Spiders get their name by waiting for prey to come close, and like lions, chase their prey for short distances. Contrary to their gangly and cumbersome appearance, Hunstman Spiders are very fast and are able to chase down their prey with ease. Hunstman Spiders are extremely aggressive, will arch up to make displays to frighten off perceived threats, and will tenaciously cling to attackers or perceived attackers if they think it will protect them. Given any other circumstance, Hunstman Spiders are designed to slip through holes and cracks and will escape if they feel outmatched.

That's all great...but what about me?!

Huntsman Spiders are not harmful to humans, and although big and scary, are certainly not strong enough to carry off or take a bite out of a human. They will bite in self-defense, in which case they are not venomous, and the only result will be a big red spider bite. As mentioned before, they do cling if picked up, and will most likely bite, making a close-up Huntsman encounter a frightening and potentially painful one, but ultimately not life-threatening.
Alright, enough scaring you...to properly answer the question, Hunstman Spiders mainly eat insects, other spiders and sometimes small lizards and snakes. Big enough Hunstmen might kill and digest very small rodents. Your pets are probably safe, unless you own very small rodents or reptiles. They do not swim, so your fish are safe, too.



They can be found in warm places where spiders thrive, particularly most of South and Central America, Africa, Australia, Asia up through southern Russia, most of Europe and most of the south and midwestern portion of the United States.

There are 1009 separate Huntsman species making up the Sparassidae Family around the world, each varying somewhat in size and shape, but maintaining the primary characteristic of having their legs extend forward, looking much like crabs' legs. For this reason, some people call Huntsmen Crab Spiders, but the Crab Spider is a completely different spider.

Huntsman Spiders favor various brown shades to fit into woodland and desert settings, have more spindly legs and are far bigger than the typical crab spider.

The Most INTELLIGENT Dog......

BORDER COLLIE (Canis familiaris)
The Border Collie is a dog breed developed in the Anglo-Scottish border region for use on farms to assist with the herding of livestock. Their intelligence has been observed as having an intuitive quality that goes well beyond basic instinct. Such sensitivity calls for an environment that regards their higher faculties; otherwise, they can become distressed. With this understanding, they are excellent companion animals.
Typically extremely energetic, acrobatic and athletic, they frequently compete with great success in dog sports, in addition to their success in sheepdog trials, and are often cited as the most intelligent of all dogs.

Description
Appearance





In general, Border Collies are medium-sized dogs without extreme physical characteristics and with a moderate amount of coat, which means not much hair will be shed. Their double coats vary from slick to lush, and come in many colours, although black and white is the most common. Black tricolour (black/tan/white or sable and white), red (chocolate) and white, and red tricolour (red/tan/white) also occur regularly, with other colours such as blue, lilac, red merle, blue merle, brindle and "Australian red"/gold seen less frequently. Border Collies may also have single-colour coats.
Eye colour varies from deep brown to amber or blue, and occasionally eyes of differing colour occur. (This is usually seen with "merles"). The ears of the Border Collie are also variable — some have fully erect ears, some fully dropped ears, and others semi-erect ears (similar to those of the rough Collie or sighthounds). Although working Border Collie handlers sometimes have superstitions about the appearance of their dogs (handlers may avoid mostly white dogs due to the unfounded idea that sheep will not respect a white or almost all white dog), in general a dog's appearance is considered by the American Border Collie Association to be irrelevant. It is considered much more useful to identify a working Border Collie by its attitude and ability than by its looks.
Dogs bred for showing are more homogeneous in appearance than working Border Collies, since to win in conformation showing they must conform closely to breed club standards that are specific on many points of the structure, coat and colour. Kennel clubs specify, for example, that the Border Collie must have a "keen and intelligent" expression, and that the preferred eye colour is dark brown. In deference to the dog's working origin, scars and broken teeth received in the line of duty are not to be counted against a Border Collie in the show ring.
Height at withers: Males from 19 to 22 in (48 to 56 cm), females from 18 to 21 in (46 to 53 cm).

Temperament
Border Collies require considerable daily physical exercise and mental stimulation. Border Collies are an intelligent breed. The breed has an instinctive desire to work closely and intensely with a human handler. Although the primary role of the Border Collie is that of the working stock dog, dogs of this breed are becoming increasingly popular as pets.
True to their working heritage, Border Collies make very demanding, energetic pets that are better off in households that can provide them with plenty of play and exercise with humans or other dogs. Due to their demanding personalities and need for mental stimulation and exercise, many border collies develop neurotic behaviors in households that are not able to provide for their needs. They are famous for chewing holes in walls and digging holes out of boredom. As a result, an alarming number of border collies end up in shelters and rescues every year. One of the prime reasons for getting rid of a border collie is their unsuitability for families with small children, cats, and other dogs, due to their intense desire to herd. 
As long as the Border Collie is in the herding/working position (crouched down, tail tucked between legs, eyes firmly fixed on the matter in hand) it considers it work. Their tails are about as long as their body.
A Border Collie's tail, based on position, shows the mindset the dog is in. A raised, wagging tail is called a "gay tail" by shepherds because it usually indicates the dog is excited and not concentrated on work. The tail lowered or tucked between the legs indicates the dog is focused and ready to listen/work.
Border Collies are now also being used in showing, especially agility, where their speed and agility comes to good use.
Though they are common choice for household pets, Border Collies have attributes that makes them less suited for certain people who have small children and cannot give them the exercise they need. As with many working breeds, Border Collies can be motion-sensitive and they may chase vehicles occasionally or a small child in the garden running around as these are both very similar to herding sheep.

Health
Lifespan





The natural life span of the Border Collie is between 10 and 17 years, with an average lifespan of twelve years. The median longevities of breeds of similar size are usually 12 to 13 years.
Leading causes of death were cancer (23.6%), old age (17.9%) and cerebral vascular afflictions (9.4%).

Common health problems





Hip dysplasia, Collie eye anomaly (CEA), and epilepsy are considered the primary genetic diseases of concern in the breed at this time. CEA is a congenital, inherited eye disease involving the retina, choroid, and sclera that sometimes affects Border Collies. In Border Collies, it is generally a mild disease and rarely significantly impairs vision. There is now a DNA test available for CEA and, through its use, breeders can ensure that they will not produce affected pups. There are different types of hip testing available including OFA (Orthopedic Foundation for Animals) and Penn Hip. Radiographs are taken and sent to these organizations to determine a dog's hip and elbow quality.
The mutation responsible for TNS has been found in Border Collies in English working dogs,in show dogs that had originated in Australian and New Zealand, and in unrelated Australian working dogs indicating the gene is widespread and probably as old as the breed itself. TNS was identified by Jeremy Shearman in the laboratory of Dr. Alan Wilton of the School of Biotechnology and Biomolecular Sciences, University of New South Wales. There is no cure, but a DNA test is now available to detect carriers as well as affected dogs. Elbow dysplasia or osteochondritis, deafness, and hypothyroidism may also occur in the breed. Dogs homozygous for the merle gene are likely to have eye and/or hearing problems.
Neuronal ceroid lipofuscinosis (NCL) is a rare but serious disease that is limited to show Border Collies. NCL results in severe neurological impairment and early death; afflicted dogs rarely survive beyond two years of age. The mutation causing the form of the disease found in Border Collies was identified by Scott Melville in the laboratory of Dr. Alan Wilton of the School of Biotechnology and Biomolecular Sciences,University of New South Wales.  There is no treatment or cure, but a DNA test is now available to detect carriers as well as affected dogs. Trapped Neutrophil Syndrome or TNS,is a hereditary disease in which the bone marrow produces neutrophils 
(white cells) but is unable to effectively release them into the bloodstream. Affected puppies have an impaired immune system and will eventually die from infections they cannot fight. TNS has been found in Border Collies in English working dogs,in show dogs that had originated in Australian and New Zealand, and in unrelated Australian working dogs indicating the gene is widespread and probably as old as the breed itself. TNS was identified by Jeremy Shearman in the laboratory of Dr. Alan Wilton of the School of Biotechnology and Biomolecular Sciences, University of New South Wales. There is no cure, but a DNA test is now available to detect carriers as well as affected dogs.






Activities

Collie needs a job. When he was unemployed, they won’t be happy. Collie is not recommended to be left alone. They need a companion, praise and intensive training. If you work outside the city, do not think to have this dog, because it really is not suitable for you. Collie have legendary intelligence. Dog competition for the program is different from others, such as speed test, obedience and of course herding sheep challenge. Border Collies are one of the most popular breeds for dog agility competitions. They also excel at competitive obedience, showmanship, fly ball, tracking, and USBCHA Sheepdog trials and herding events.



Dog sports





Border Collies excel at several dog sports in addition to their success in sheepdog trials. Because of the high instinct of herding, they are excellent at this sport. Herding instincts and trainability can be tested for when introduced to sheep or at noncompetitive instinct tests. Border Collies exhibiting basic herding instincts can be trained to compete in sheepdog trials and other herding events. They perform well at some higher jump heights at dog agility competitions, so much so that in England, competitions often include classes for ABC dogs, "Anything But Collies".
The Border Collie's speed, agility, and stamina have allowed them to dominate in dog activities like fly ball and disc dog competitions. Their trainability has also given them a berth in dog dancing competitions.
Border Collies have a highly developed sense of smell and with their high drive make excellent and easily motivated tracking dogs for tracking trials. These trials simulate the finding of a lost person in a controlled situation where the performance of the dog can be evaluated, with titles awarded for successful dogs.
Search and rescue
Because of their skills, Border Collies make excellent search and rescue dogs in lowland, mountain, and urban areas. They have been trained in air-scenting, ground-scenting and as cadaver dogs.

  • Goliath Frogs are mute ~ they do not make noise
  • They can leap 10 feet
Lifespan
  • The goliath frog can live up to 15 years.
Food
  • Adults are carnivores that eat insects, crustaceans, fish, and amphibians.
  • Tadpoles (baby frogs) are herbivores that eat water plants found only near waterfalls and in rapids.
  • Some indigenous people eat Goliath Frogs
Reproduction
  • Mating season for the Goliath Frog is July and August
  • Reproduce sexually
  • Several hundred eggs are included in each egg mass, which are attached to plants growing on the bottom of the river
  • It takes 85 to 90 days for tadpoles to develop

Relations with Humans
  • Goliath frogs were considered to be a source of food in some parts of west Africa.
  • They were also highly exported to zoos and animal dealers to be sold as pets. Unfortunately, these frogs fail to thrive in captivity (and almost never reproduce there).
  • Due to their classification as endangered, the Equatorial Guinean government has declared that no more than 300 goliaths may be exported out of the country per year.
  • Some are captured and kept as pets.
