Atlantic Jellyfish

Jellyfish have drifted along on ocean currents for millions of years, even before dinosaurs lived on the Earth. They are abundant in cold and warm ocean water, in deep water, and along coastlines. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them.

There are many types of jellyfish in the ocean. These jelly-like creatures pulse along on ocean currents. Inside their bell-shaped body is an opening that is its mouth. They eat and discard waste from this opening. As jellyfish squirt water from their mouths they are propelled forward. Tentacles hang down from the smooth bag-like body and sting their prey. 

Jellyfish stings can be painful to humans and sometimes very dangerous. But jellyfish don't purposely attack humans. Most stings occur when people accidentally touch a jellyfish, but if the sting is from a dangerous species, it can be deadly. The Australian box-like sea wasp is the most toxic to humans. 

Loggerhead Sea Turtles

These beautifully colored sea turtles got their name because their oversized head sort of looks like a big log.

Within their heads are powerful jaws, which loggerheads use for crushing prey like conchs, horseshoe crabs, and other animals with hard shells. They also eat softer foods like jellyfish, fish, seaweed, and a brown algae called sargassum.
Loggerheads live in oceans all over the world, except in the coldest seas. There are more loggerheads in the waters of the United States than any other species of sea turtle. Even so, loggerheads are threatened by many things, including predators, pollution, human development in the turtles' nesting areas, and fishing nets.
