If you can get past any moral conflicts, you can eat anything that is not poisonous. There are some animals like the blow fish which is poisonous, but it can be eaten if its cut by a skilled and licensed chef, its typically eaten raw as sashimi. From a biblical perspective…
1 Timothy 4:3-5
3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
4 For every creature of God is good, and nothing to be refused, if it be received with thanksgiving:
5 For it is sanctified by the word of God and prayer.
