World's Most Dangerous Animals

10. Shark 30 -100 deaths per year.

Sharks are fish with a full cartilaginous skeleton and a streamlined body. They respire with the use of five to seven gill slits. Sharks have a covering of dermal denticles to protect their skin from damage, parasites and to improve fluid dynamics.

9. Jellyfish over 100 deaths per year.

Jellyfish are marine invertebrates belonging to the Scyphozoan class, and in turn the phylum Cnidaria. The body of an adult jellyfish is composed of a bell-shaped, jellylike substance enclosing its internal structure, from which the creature's tentacles suspend.

8. Hippopotamus over 200 deaths per year.

6. Bee over 400 deaths per year.

Bees are flying insects, closely related to wasps and ants. There are approximately 20,000 species of bees, and they may be found on every continent except Antarctica. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source, and the latter primarily for protein and other nutrients.

5. Elephant over 600 deaths per year.
