Marine biology is the scientific study of organisms in the sea.

Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment, while biology is the study of the organisms themselves.

A boat is a watercraft of a large range of sizes designed to float, plane, work or travel on water.

Small boats are typically found on inland waterways (e.g., rivers and lakes) or in protected coastal areas.

However, boats such as the whaleboat were designed for operation from a ship in an offshore environment.

In naval terms, a boat is a vessel small enough to be carried aboard another vessel (a ship).

Another less restrictive definition is a vessel that can be lifted out of the water.

Some definitions do not make a distinction in size, as bulk freighters long on the Great Lakes are called oreboats.

For reasons of naval tradition, submarines are usually referred to as 'boats' rather than 'ships', regardless of their size and shape.

Ships are generally distinguished from boats based on their larger size, shape and cargo or passenger capacity.

An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere.

On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface.

These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans.

The word sea is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land.

A machine is a tool containing one or more parts that uses energy to perform an intended action.

Machines are usually powered by chemical, thermal, or electrical means, and are often motorized.

Historically, a power tool also required moving parts to classify as a machine.

However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.
