They all live at the surface of the open ocean, and are colonies of carnivorous, free-floating hydroids. Their life-style in the plankton is similar to that of pelagic jellyfish.
The chondrophores look like a single organism but are cooperatives of polyps.
The most familiar members of the family Porpitidae are the blue button ("Porpita porpita") and the by-the-wind sailor ("Velella velella").
Chondrophores may look like a jellyfish, but they really are not. Like the siphonophores they are not a single animal. They are a colony of clones, genetically identical zooids. These zooids are small, highly modified individual polyps. Though structurally similar to other cnidarians, the zooids do not live by themselves: they are attached to each other. Each type of zooid depends for survival on the others doing what it cannot do by itself.
This kind of set-up is also found in the siphonophores: the Portuguese man o' war. They evolved independently, and are classified in different orders.
A rare soft-bodied fossil was got from Mississippian strata in northeastern Kentucky. It was interpreted as a chondrophorine float. The origin of the group was probably in the Neoproterozoic era, some 650540 million years ago.

Impact event
An impact event is a collision between objects in space. They happen regularly in planetary systems, such as our Solar System. They most often involve small objects, such as asteroids, comets or meteors. These have relatively little impact. When a large object collides with a planet like the Earth, it can have serious effects on the planet. We try to find out when one is going to hit Earth using impact prediction. Depending on the size of the object, much of the impact is reduced by the planet's atmosphere. Smaller objects explode or break apart as they enter the atmosphere. These are seen as bolides.
Impact craters, which are caused by impact events, can be seen on many of the planets and other objects in the Solar System. Some of the largest are on Mars and the Moon. These are said to be evidence of major impact events. The first time an impact event was recorded was in July 1994. A comet, Shoemaker–Levy 9, broke apart and collided with Jupiter. The collision was recorded by telescopes and satellites.
Impact events appear to have had a major effect on the how the Solar System has changed since it was formed. Major impact events have also shaped the history of the Earth, including the evolution of life. It is thought that the Chicxulub impact, which happened 66 million years ago, caused the Cretaceous–Paleogene extinction event. There is debate over whether impacts caused any of the other extinction events throughout history. A giant impact event is thought to have produced the Moon.
Hundreds of impacts have been reported on Earth. Many happen without being seen by anyone on the ground. On average, asteroids with a diameter of impact Earth about once per year. These usually explode in the upper atmosphere, and most or all of the solids are vaporised. Asteroids with a diameter of collide with Earth every 500,000 years. Large collisions, of , happen once every twenty million years. Some much smaller asteroids have caused damage and injuries, but no human is known to have been killed directly by an impact. The Chelyabinsk meteor event in 2013 is the only impact event known to have resulted in a large number of injuries. It was about 20 metres wide. One of the most well-known impacts in modern times was the Tunguska event. This happened in Siberia in 1908. Impacts of that size are said to happen about once every thousand years.
Tripod (photography)
A tripod is a tool for balancing cameras. Without a tripod, it can be hard to keep a camera steady. A tripod is very useful when taking pictures in low light.
