Are shellfish haram or halal? I've honestly heard different things about this, one is that everything in the sea is halal, and the other is that shellfish are haram because we still follow all Jewish dietary laws.
The reasoning behind pigs, dogs, ect. being haram is basically because they are nature's garbage disposals and they eat anything including the trashiest stuff out there (more then they can filter out of their bodies) so they end up having lots of toxins in their meat and are more likely to have worms and diseases then other animals.
If we look at shellfish they also seem to eat a lot of trash (crabs basically eat trash off the sea floor right?), but it is also harder to tell for some shellfish exactly what they eat or do.
What have you guys heard about all this, and what are your opinions?
