Pukas - Synonyms and definition

Synonyms for Puka(s) are:  Púca, Phooka, Phuka, Pooka, Pwca, Bwca, Bucca,…

Pukas are per definition weird entities, first described in celtic mythology.
They are mostly nasty contemoraries, which can do magic, change their shape,
and also tease dump farmers and betray them for their crop yields.

This page is about a special subgroup of Pukas, which are more pleasant and nicer than the beings known from Celtic mythology.
These contemporaries gained fame through the documentary by Mary Chase on a representative of the species Lepctolagus harveyensis (Harvey)
from 1943, but there mistakenly classified as a 'hare'.

This three-part documentary was misunderstood as a play and even as a comedy, and performed countless times as a stage play since November 1944
under the title "Harvey" (in German "My friend Harvey"), 1945 awarded the Pulitzer Prize and filmed several times (e.g. by Henry Koster in 1950, with James Stewart in the leading role).

Suggesting a pedigreee and systematics

Due to the lack of genetic data, the following attempt to establish a pedigree of
Nessies, Pukas, Wolpertingers and Jackalopes is based on phenotypic traits.
However, here we only deal with Polelagotia and Demolagotia.
For others see here: Jackolopes and Wolpertingers.

The yet known 19 species of Lepolagotia are shortly presented here.

Habitat and ecology

Pukas populate the most extreme habitat imaginable: another living being – i.e. Homo sapiens.

Pukas are highly specialized and live not only in the immediate vicinity of humans, but even at or on them – however, are often either not noticed at all (although they are not to be overlooked), or simply ig-nored by people (that is, that they are noticed but, since not fitting into their way they see the world, these people just decided to ignore the Pukas they see). The previously mentioned propaganda of Puka deniers leads some people not to dare exchange with others about their discovery / observation they or others "have" a Puka. This is also due to being afraid from being declared crazy; the already mentioned book / film "Harvey" also made this point quite clear. 

Pukas are in every respect extraordinary. So far, none of these beings have been observed ingesting any kind of food, even though they have at least one masticatory apparatus. Here only the assumption can be expressed that, and much indicates for it, the Pukas feed on the affection of the person on / with they live. However, physiologically, this is still unexplored and not resolved in detail.

Equally incomprehensible are other phenomena, which can only be reviewed in the following and await a scientific explanation. For ex-ample, despite its sometimes enormous size (up to 3 m!), a Puka has such a low density that it never becomes a burden to its (human) "carrier". Nevertheless, Pukas so far neither became doomed by gusts of wind, nor injuries were reported yet; the latter would be quite conceivable due to shoving in dense crowds or carelessness of the human partner. Even deaths of Pukas are unknown so far.

Also, the already mentioned fact that a Puka is only visible to those people who accept their existence and not for others who consider them as fundamentally non-existent, is difficult to explain by the known and accepted rules or laws of biology and physics. The phenomenon that it is impossible to take a photograph from a Puka may be related to this in some way; therefore only drawings could be used in this essay in order to be able to convey to the ignorant "non-believers" the variety of forms in Pukas.

It is clear that Pukas are a very adaptable group of living things. So far, no observations or statements of the Pukas are available on the nature of reproduction and propagation of these animals. The assumption that reproduction takes place only when Pukas are current-ly without a human partner is close. Because of what is known about Wolpertinger must be assumed that Pukas would also have to be egg laying.
