Spaceships of the universe

As civilizations advance, they feel the need to know more, they want to explore the unknown, they want to explore the space and it's this desire of knowledge that has led various races throughout the universe to create the massive empires that stretch throughout solar systems, and even throughout galaxies. Of course to travel the massive distances from one planet to another or even more you'd need a vehicle, a space vehicle. 
Here we can see 2 types of spaceships, each pair belonging to two different races. The large ship on top is a Chronoan Herroware, a group of large ships, ranging in diameter from just 20 m to over 100 m and are used for various purposes, from exploaration, private ownership and even military services. The small disk-like ship under it is a Barryome, an individual kind of ship often used for one person journeys in space, usually not for long distances and most commonly used in the Chronoan military.
Meanwhile the large spaceship in the bottom is a large Deluvian herroware, used for the very same purposes, while the somewhat plane-shaped, smaller ship is a kind of Deluvian Barryome. The thing about Deluvian spaceships and a great deal of their technology is that it's organic, meaning that these spaceships are in fact, genetically modified (GM for short) creatures from the Deluvian homeworld, Deluvis (Deluvians are one of the few alien races to name their race after their planet). Mane Deluvian spaceships have the ability to breed and instead of usual fuel, require food, which since they're genetically modified, can come from various sources, such as light, creatures, even minerals and usual fuel. Deluvian spaceship genes have a relatively low plasticity, so while after several generations of breeding a ship may look a bit different from it's great grandfathers, it's still relatively unchanged and  since it has the same functions, there rarely happen any changes that may effect the way the ship does its' job. 
Deluvian ships are unlike most Deluvian technology, conscious beings and have are GM to do their job and are often quite friendly creatures. Being so large, they require several brains, most Herrowares having 3, while the smaller Barryomes have only one.

P.S- "Herroware" and "Barryome" are alien words and have not been invented by humans, but belong to a very old Chronoan language that is widely used by other races in the same way some foreign people may use English to communicate.
