This image features a rock specimen, likely a fossil or coral, with a textured surface showcasing distinct patterns and formations. The rock has an irregular shape with complex surface details that may indicate historical biological activity, such as the presence of coral polyps or other marine organisms. **Measurement Detail:** Below the rock is a scale in centimeters. The rock measures approximately 10 centimeters across its widest point, based on the visible ruler markings. This type of specimen is commonly used in educational settings to study geological formations, fossil records, or marine life history. The texture and patterns provide valuable information about the environment and conditions in which the rock or fossil was formed.

Classification of Marine Organisms

Classification is a way of categorizing organisms that enables an easy process of identification of such organisms. All living things are classified by grouping them under specific categories. The grouping is done based on the close relativeness of the organisms. The classification tool requires knowledge of characteristics, differences, and similarities between different organisms.
