While camels are actually
not true ruminants they
chew cud, and for not having a cloven hoof, or a hoof at all. Camels have toes with hoof like toenails.
Although hares and coneys do not ruminate at all, they do usually re-ingest
soft cecal pellets made of chewed plant material right after excretion for further bacterial digestion in their stomach and this serves the same purpose as rumination.
Although not
ruminants, hyraxes have complex, multichambered stomachs that allow symbiotic bacteria to break down tough plant materials, though they do not regurgitate. Further clarification of this classification has been attempted by various authors, most recently by Rabbi

In an attempt to help identify animals of ambiguous appearance, the
Talmud, in a similar manner to
Aristotle's earlier ''
Historia Animalium'', argued that animals without upper teeth would always chew the cud and have split hoofs (thus being ritually clean), and that no animal with upper teeth would do so; the Talmud makes an exception for the case of the camel (which, like the other ruminant even-toed ungulates, is apparently 'without upper teeth' though some citations
[''Jewish Encyclopedia'', ''Dietary Laws'']), even though the skulls clearly have both front and rear upper teeth. The Talmud also argues that the meat from the legs of clean animals can be torn lengthwise as well as across, unlike that of unclean animals, thus aiding to identify the status of meat from uncertain origin.
Origin
Many Biblical scholars believe that the classification of animals was created to explain pre-existing
taboos.
[''Peake's commentary on the Bible''] Beginning with the
Saadia Gaon, several Jewish commentators started to explain these taboos rationalistically; Saadia himself expresses an argument similar to that of
totemism, that the unclean animals were declared so because they were worshipped by other cultures. Due to comparatively recent discoveries about the cultures adjacent to the Israelites, it has become possible to investigate whether such principles could underlie some of the food laws.
Egyptian priests would only eat the meat of
even-toed ungulates (swine, camelids, and ruminants), and rhinoceros.
[ Porphyry, ''De Abstinentia'' 4:7] Like the Egyptian priests, Vedic India (and presumably the Persians also) allowed the meat of rhinoceros and ruminants, although cattle were excluded from this, since
they were seemingly taboo in Vedic India;
["Laws of Apastamba" 1:5, 1:29-39, 2:64][''Laws of Vasishta'', 14:38-48, 14:74][''Laws of Bandhayuna'', 1:5, 1:12, 14:184] in a particular parallel with the Israelite list, Vedic India explicitly forbade the consumption of camelids and domestic pigs (but not
boar).
However, unlike the biblical rules, Vedic India did allow the consumption of hare and porcupine,
but
Harran did not, and was even more similar to the Israelite regulations, allowing all ruminants, but not other land beasts, and expressly forbidding the meat of camels.
[Daniel Chwolson, ''Die Szabier und der Szabismus'', 2:7]
It is also possible to find an ecological explanation for these rules. If one believes that religious customs are at least partly explained by the ecological conditions in which a religion evolves, then this too could account for the origin of these rules.
Modern practices
In addition to meeting the restrictions as defined by the
Torah, there is also the issue of ''
masorah'' (tradition). In general, animals are eaten only if there is a ''masorah'' that has been passed down from generations ago that clearly indicates that these animals are acceptable. For instance, there was considerable debate as to the kosher status of
zebu and

and both state that anything residing in "the waters" (which Leviticus specifies as being the seas and rivers) is ritually clean if it has both
fins and
scales, in contrast to anything residing in the waters with neither fins nor scales.

Leviticus describes them as an "abomination" KJV Leviticus 11:10. Abomination is also sometimes used to translate and .
Although the Old Testament does not further specify, the
Talmud makes the claim that all fish that have scales also have fins, and so practically speaking, we need to only identify organisms that have scales and can ignore the portion of the rule about fins.

Origin
Nachmanides believed that the restrictions against certain fish also addressed health concerns, arguing that fish with fins and scales (and hence ritually clean) typically live in shallower waters than those without fins or scales (i.e., those that were ritually impure), and consequently the latter were much colder and more humid, qualities he believed made their flesh toxic.
[Nachmanides, ''Bi'ur'' on Leviticus]
The academic perception is that natural repugnance from "weird-looking" fish is a significant factor in the origin of the restrictions.
[Cheyne and Black, ''Encyclopedia Biblica''] Vedic India (and presumably the Persians also) exhibit such repugnance, generally allowing fish, but forbidding "weird looking" fish and exclusively carnivorous fish;
in Egypt, another significant and influential culture near to the Israelites, the priests avoided all fish completely.

Although the first 10 birds identified by the Septuagint seem to fit the descriptions of the Masoretic Text, the ossifrage (
Latin for "bone breaker") being a good example, the correspondence is less clear for most of the remaining birds.
It is also obvious that the list in Leviticus, or the list in Deuteronomy, or both, are in a different order in the Septuagint, compared to the Masoretic Text.
Attempting to determine the correspondence is problematic; for example, "pelican" may correspond to ("vomiting"), in reference to the pelican's characteristic behaviour, but it may also correspond to ("cup"), as a reference to the pelican's jaw pouch.

s (because the Hebrew Bible distinguishes animals into four general categories—beasts of the land, flying animals, creatures which crawl upon the ground, and animals which dwell in water—not according to modern scientific classification).
Most of the remaining animals on the list are either
birds of prey or birds living on water, and the majority of the latter in the list also eat fish or other seafood.
The Septuagint's version of the list comprehensively lists most of the birds of Canaan that fall into these categories. The conclusion of modern scholars is that, generally, ritually unclean birds were those clearly observed to eat other animals.
Although it does regard all birds of prey as being forbidden, the Talmud is uncertain of there being a general rule, and instead gives detailed descriptions of the features that distinguish a bird as being ritually clean.
The Talmud argues that clean birds would have
craws, an easily separated 'double-skin', and would eat food by placing it on the ground (rather than holding it on the ground) and tearing it with their bills before eating it;
[''Hullin'' 63a] however, the Talmud also argues that only the birds in the biblical list are actually forbidden—these distinguishing features were only for cases when there was any uncertainty in the bird's identity.
Origin
The earliest rationalistic explanations of the laws against eating certain birds focused on symbolic interpretations. The first indication of this view can be found in the 1st century BC
Letter of Aristeas
The Letter of Aristeas to Philocrates is a Hellenistic work of the 3rd or early 2nd century BC, considered by some Biblical scholars to be pseudepigraphical. Harris, Stephen L., ''Understanding the Bible''. (Palo Alto: Mayfield) 1985; André Pell ...
, which argues that this prohibition is a lesson to teach justice, and is also about not injuring others.
Such allegorical explanations were abandoned by most Jewish and Christian theologians after a few centuries, and later writers instead sought to find medical explanations for the rules; Nachmanides, for example, claimed that the black and thickened blood of birds of prey would cause psychological damage, making people much more inclined to cruelty.
However, other cultures treated the meat of certain carnivorous birds as having medical benefits, the
Romans viewing owl meat as being able to ease the pain of insect bites.
Conversely, modern scientific studies have discovered very toxic birds such as the
pitohui
The pitohuis are bird species endemic to New Guinea. The onomatopoeic name is thought to be derived from that used by New Guineans from nearby Dorey (Manokwari), but it is also used as the name of a genus '' Pitohui'' which was established by the ...
, which are neither birds of prey nor water birds, and therefore the biblical regulations allow them to be eaten.
Laws against eating any carnivorous birds also existed in Vedic India
and Harran,
and the Egyptian priests also refused to eat carnivorous birds.
Modern practical considerations

Due to the difficulty of identification, religious authorities have restricted consumption to specific birds for which Jews have passed down a tradition of permissibility from generation to generation. Birds for which there has been a tradition of their being kosher include:
*
Chicken

Chukar partridge

—the word literally means "hider". The
Book of Numbers implies that they were particularly small. The Septuagint calls it an , and it has usually been translated as grasshopper.
The Mishnah argues that the ritually clean locusts could be distinguished as they would all have four feet, jumping with two of them, and have four wings which are of sufficient size to cover the entire locust's body. The Mishnah also goes on to state that any species of locust could only be considered as clean if there was a reliable tradition that it was so.
The only Jewish group that continue to preserve such a tradition are the
Jews of Yemen, who use the term "kosher locust" to describe the specific species of locusts they believe to be kosher, all of which are native to the

Due to the difficulties in establishing the validity of such traditions, later
rabbinical authorities forbade contact with all types of locust to ensure that the ritually unclean locusts were avoided.
Small land creatures

Like many of the other biblical lists of animals, the exact identity of the creatures in the list is uncertain; medieval philosopher and Rabbi,
Saadia Gaon, for example, gives a somewhat different explanation for each of the eight "creeping things." The Masoretic Text names them as follows:
