Iberian Orcas Collide with Boats in High Seas Mystery.

Iberian orcas have been bumping into boats off the coast of Spain, causing concern among conservationists. The reason for the behavior is unknown, but some speculate it could be due to a decline in the orcas' food sources or increased boat traffic in the area. Efforts are underway to study the orcas and find ways to protect both the marine mammals and boaters.
