Interestingly enough, many cryptids have been "caught" but they always end up being dismissed by scientists. Granted these creatures are usually
dead when found or killed when encountered, but specimens have been obtained.
I think there are several hurdles facing aquiring specimens and proving their existance.
a) They are obviously rare and elusive, locating them alone is an immense task. Most of these creatures are found in very remote locations, are very
rare, and seek to evade man. Many known species have been thought to be extinct only to be rediscovered.
b) Some of these creatures are very large and powerful like the Sasquatch and Sea Serpents/Lake Monsters. A typical Sasquatch (Gigantopithecus) is
estimated to be 7.5-10 feet in height and weigh 600-1100 pounds. Being that a Gorilla has the strength of 10 men, one of these is estimated to have
the strength of 15-20 men.
Sea Serpents/Lake Monsters are usually estimated to be from 30-100+ feet in length, weighing from a few to many tons.
These creatures would be next to impossible to capture alive and very difficult to contain and transport.
c) Many creatures corpses have been obtained, however scientists continually refute the evidence. Look at the recent supposed Chupacabra corpses
recently aquired. They do not match the description of any known animal, if you've seen the pictures in the newspapers or on T.V. you realize they
should be studied, however scientists and "specialists" are quick to dismiss them, stating that they are creatures which they obviously aren't.
Perhaps you've heard of De Loy's Ape, a five foot ape-like creature killed and photographed by a famous scientist who was doing research in S.
America. The Thunderbird, a giant bird-like creature with a 25-30 ft. wingspan one of which was even placed within a museum (there are two different
varieties to date one with bat-like skin and dinosaur features, the other variety a giant bird). There's also been giant octopi, squids, and even
corpses of possible sea monsters discovered. Each time scientists were quick to dismiss them. (However, scientists did end up acknowledging the
existance of giant squids due to a later satellite picture. Odd that a corpse was not enough evidence, but a satellite photo was.)
It's only when they are faced with living, moving, indisputable truth that scientists seem willing to admit to the existance of a cryptid. Having
taken courses in Marine Biology, Anthropology, etc., I think it's because they feel the existance of creatures they've declared extinct or
non-existant will throw doubt on much of their "convential wisdom". Since most of the world's history is based upon their assumptions and
potentially incorrect methodologies (like Carbon Dating, and the extinction of dinosaurs before man's existance) they are quick to protect their
doctrines.
I have personally encountered multiple cryptids and each time I tried to report the incident to the proper authorities, I was met with skepticism at
best, mockery at worst. What made it worse was that these were personal sightings, I have spent more time in the field than almost any scientist I've
met, and the cryptids I reported should not have seemed so unbelievable. A Black Panther (Fairhope, AL, USA) and a large, dark colored wolf (Smoky
Mnts., NC, USA) were two cryptids I reported only to have most of the scientists dismiss it and walk off during my report.
I truly believe until scientists are willing to open their mind to the possibility of cryptids anything short of a living, squirming, squeeling
cryptid irrefutably placed before them will continue to be dismissed.
Until then the only new species you'll see acknowledged will be species
whose existance doesn't throw doubt on modern scientific theory.
Here's some interesting links which show a small portion of the evidence out there:

Check out subsection "Big Foot Creatures/Footprints" in the above link. It's an eye opener.)
My Grandfather participated in the excavation of one of the sites mentioned in the above link where they discovered evidence of humans living
alongside dinosaurs. I've seen the evidence myself, it's set in stone, indisputable, but most scientists had a fit when they heard about it,
denouncing it without ever visiting the site.
You have to ask yourself:
a) Why aren't most scientists interested in trying to search for evidence of cryptids instead of sitting in an office trying to debunk any evidence
of them?
b) How is that every civilization on every continent has legends, recordings, art, or pictures (including cave art) of "dragons", dinosaurs,
cryptids, or animals we know to have existed but suposidly died out "millions of years ago" (according to scientists). How did those
scholars/artisians know what extinct, unearthed dinosaurs/prehistoric creatures looked like in order to draw them in the middle ages? Hmmmm....
Sorry for my ranting, I just feel I have seen enough to understand why most cryptids aren't acknowledged, investigated, or researched by the
mainstream scientific community. It's not that they are uncatchable, it's that the mainstream scientific community isn't interested in catching
them.
