It is a natural thing for animals to die, and the death of these sharks were not due to neglect among the aquariums part. Divers photograph the animal right above their pectoral fins and behind their gill slits. Also, whered they get veterinarians trained to manage whale shark health?

For example, I am a visual learner, so the combination of reading the information about the animal provided on the sign with the presence of the animal reinforced what I had just read.

The majority of whale sharks that are kept in captivity do not fare well. WWF also supports whale shark studies to learn more about the population, their habitat use and migratory pathways in the waters surrounding Mafia Island, Coastal East Africa. By sparking the awareness, fascination (funds) for these creatures they are given a greater opportunity for survival in the big picture. The media and animal activists love to dwell in the seeming I told you so stories (such as the death of the two whale sharks) however, seeing how they WERE destined to die before they were even brought to live in the seemingly ample conditions in the first place, it is not as if their lives were extended somewhat anyways.
