An '''[[iceberg]]''' is a large piece of freshwater [[ice]] that has broken off a [[glacier]] or an [[Ice-shelf|ice shelf]] and is floating freely in open water. It may subsequently become frozen into [[pack ice]] (one form of sea ice). As it drifts into shallower waters, it may come into contact with the seabed, a process referred to as seabed gouging by ice. About 90% of an iceberg is below the surface of the water.
The '''[[Orca]]''' is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and [[Antarctica|Antarctic]] regions to tropical seas.


In addition to size classification, icebergs can be classified on the basis of their shape. The two basic types of iceberg forms are tabular and non-tabular. Tabular icebergs have steep sides and a flat top, much like a plateau, with a length-to-height ratio of more than 5:1. This type of iceberg, also known as an ice island, can be quite large, as in the case of Pobeda Ice Island. [[Antarctic]] icebergs formed by breaking off from an [[ice-shelf|ice shelf]], such as the [[Ross Ice Shelf]] or [[Filchner-Ronne Ice Shelf]], are typically tabular. The largest icebergs in the world are formed this way.

The Orca is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.
