A recent study suggests that manta rays may be self-aware as they reportedly waved at themselves and changed their behavior when in front of a mirror.
When a one-ton giant manta ray with a wingspan of 23 feet was caught last year in gill nets made by Peruvian fisherman, conservationists called for action. These treasured marine creatures are particularly vulnerable to overfishing and bycatch.
A recent day on the Internet had the hashtag Flatshark. There are more than 500 rays and skates -- the "flatsharks" in question, all related to sharks. As public opinion turns in favor of sharks, scientists would like to see rays get attention, too.
