Taste is arguably the pickiest sense we have, and we avoid tasting anything we don't like to sometimes dangerous degrees. We humans are extremely lucky we only have tastebuds in our mouth, or day-to-day tasks would be much less convenient. The catfish has 100,000 tastebuds, 10 times MORE than humans, and they are ALL OVER its body, and most sensitive in its whiskers. You may not want to believe this whiskered water-worm is more influential than you are, but consider this.
