Jellyfish or jellies are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.

 

The brown bear (Ursus arctos) is a large bear distributed across much of northern Eurasia and North America. He is the largest land-based predator.

 

The giant squid (genus: Architeuthis) is a deep-ocean dwelling squid in the family Architeuthidae, represented by as many as eight species. Giant squid can grow to a tremendous size : recent estimates put the maximum size at 13 m (43 ft).

 

Pufferfish are generally believed to be the second most poisonous vertebrates in the world, after the golden poison frog. Certain internal organs, such as liver, and sometimes the skin, are highlytoxic to most animals when eaten; nevertheless, the meat of some species is considered a delicacy in Japan Korea and China when prepared by chefs who know which part is safe to eat and in what quantity.

The gulper eel, known scientifically as Eurypharynx pelecanoides, is perhaps one of the most bizarre looking creatures in the deep ocean. Its most notable attribute is the large mouth. The eel's mouth is loosely hinged, and can be opened wide enough to swallow an animal much larger than itself.
