I suppose this is little dark of me. But consider that the pig, with it's split hooves, appears kosher on the outside. But because it does not chew its cud, is not kosher on the inside. (Kosher livestock must show both signs.)
Deuteronomy 14:3 – 8
ד. זֹאת הַבְּהֵמָה, אֲשֶׁר תֹּאכֵלוּ: שׁוֹר, שֵׂה כְשָׂבִים וְשֵׂה עִזִּים.
4. These are the beasts which ye may eat: the ox, the sheep, and the goat,
ה. אַיָּל וּצְבִי, וְיַחְמוּר; וְאַקּוֹ וְדִישֹׁן, וּתְאוֹ וָזָמֶר.
5. the hart, and the gazelle, and the roebuck, and the wild goat, and the pygarg, and the antelope, and the mountain-sheep.
ו. וְכָל-בְּהֵמָה מַפְרֶסֶת פַּרְסָה, וְשֹׁסַעַת שֶׁסַע שְׁתֵּי פְרָסוֹת, מַעֲלַת גֵּרָה, בַּבְּהֵמָה--אֹתָהּ, תֹּאכֵלוּ.
6. And every beast that parteth the hoof, and hath the hoof wholly cloven in two, and cheweth the cud, among the beasts, that ye may eat.
