Sponges are an ancient class of multicellular organisms that belong to a unique group in the animal kingdom. Its diverse forms and rich colors have attracted the attention of countless biologists. The structure of sponge is relatively simple, composed of many cells, but there is no clear tissue and organ, mainly composed of sponge matrix, needle structure and cells, forming a unique ecosystem.
Sponge specimens are not only important data for Marine ecological research, but also a window to display the diversity of Marine life. The specimen usually retains the original form of the sponge, and after proper treatment, it can be preserved for a long time in the laboratory or display place. By observing these specimens, we can reveal the morphological characteristics and living habits of sponges. Sponges carry fine particles and nutrients into their bodies by flowing water, and use special cells to filter and ingest them, demonstrating a very unique lifestyle.
Sponges play an important role in the ecosystem. They enrich microscopic organisms in the ocean, provide habitat, and act as effective filters in water bodies, improving water quality. The study of specimens not only helps scientists understand the ecological function of sponges, but can also reveal their importance in maintaining the ecological balance of the ocean.
The diversity of sponges is equally evident in their shapes and colors, and specimens often display stunning beauty. From simple tubes and cups to complex dendritic shapes, sponges in various forms demonstrate the ingenious design of nature. At the same time,the color of the sponge is also very rich,often depending on the living environment,showing a variety of colors such as yellow,red,blue, green,etc.,which is dizzying.
The collection and study of sponge specimens not only provide valuable empirical data for biology,but also provide important clues for people to understand the overall picture of Marine ecology.

Sponges are an important part of Marine ecosystems and are known for their unique morphology and diverse functions. Sponge specimens are usually produced by collecting and handling sponges and can provide researchers with valuable information about their biological characteristics and ecological functions. These specimens not only show the structural characteristics of sponges, but also reflect their growth environment and ecological adaptability.
The structure of sponges is very simple, mainly composed of cells and the matrix between cells. They do not have organs and tissues in the traditional sense, but are able to circulate water for nutrients and oxygen. Sponges have amazing regenerative abilities and can quickly repair and resume their growth after partial damage. This property makes sponges an important object for studying regenerative biology.
When collecting sponge specimens, gentle methods are usually used to avoid damage to the Marine ecosystem. During the preservation of specimens, it is necessary to maintain the morphological structure of sponges in order to facilitate subsequent observation and analysis. Common preservation methods include drying and fixation in special liquids. These specimens were classified and identified in the laboratory, providing scientists with the basis for taxonomic, ecological and physiological studies of sponges.
The study of sponge specimens has revealed the key role of sponges in the food chain, not only as a habitat for certain Marine organisms, but also their ability to filter water and purify the Marine environment. In addition, sponges also have a rich chemical composition, and many studies are working to extract new drugs from sponges to tackle various diseases in modern medicine.
In summary, sponges not only show the diversity and complexity of Marine life, but also provide a valuable resource for scientific research.

Sponges are an ancient and unique group of creatures whose specimens display stunning forms and structures. Despite their apparent simplicity, sponges play an important role in ecosystems. As benthic organisms, they usually attach to the bottom of the water and obtain nutrients through special filtration systems. The sponge's body is made up of many small holes and channels, which allow water to flow through constantly, extracting tiny organic matter and nutrients from it.

The preparation process usually involves collecting fresh sponges and drying them while preserving their form. This process preserves the sponges' fine structure, allowing them to be observed for their distinctive fibrous or porous appearance. Different types of sponges vary significantly in form, color and texture, creating a rich and varied visual experience. From soft sponges to hard, stony sponges, the specimens represent the diversity of this species.

In addition to the diversity of forms, the role of sponges in the ecosystem cannot be ignored. They help clean the environment and maintain water quality by filtering water bodies. Sponges also provide habitat and protection for many Marine life. Its internal structure provides shelter for other organisms, forming a rich microbial community. In some Marine ecosystems, sponges are also involved in nutrient cycling and play an important role in the overall ecological balance.

By appreciating and studying sponges, one can not only understand how unique these creatures are, but also gain a deeper understanding of the complexity of Marine ecology. In the context of today's environmental changes, it is particularly important to protect the diversity of Marine life. As an important part of the ecosystem, sponges deserve our attention and concern.

Sponges also play an important role in art and culture. Its unique form and texture are often a source of inspiration for creation.
