Pictured above are Pacific sea nettles, or Crysaora fuscescens. These come from the phylum Cnidaria. Cnidaria comes from the domain Eukaryota and the kingdom Animalia. The bell of the sea nettle can grow larger than one meter, or three feet, in diameter, but most are less than 50 centimeters across. They have 24 undulating maroon tentacles that can drag behind the Pacific sea nettle as far as 15 feet. It has a sting, but it is rarely dangerous. Its tentacles are used for protection and to kill its food. As this organism drifts throughout the ocean, it captures its prey in its tentacles, killing it with the toxins released, or its "stings," and moves the prey up to its mouth as it begins digestion.
The Pacific sea nettles are capable of asexual production in its polyp stage, and sexual reproduction in its medusa stage. It's Latin name Chrysaora comes from the Greek mythological Chrysaor, brother of Pegasus and son of Medusa and Poseidon. Chrysaor translated means "he who has a golend armament."
