What is one of the other items that divers commonly collect?

While divers may collect various items while submerged, algae is commonly noted as a collection target for educational or scientific purposes. Algae can provide valuable information regarding the health of an aquatic environment, the presence of toxins, or the overall biodiversity of an ecosystem.

Collecting algae can help divers and researchers study the effects of pollution and climate change on marine life. Unlike other items such as shellfish, which have specific legal restrictions or health advisories associated with their collection, or sand and pipes, which may not have the same ecological significance, algae offers both scientific value and a means of understanding environmental conditions. This focus on ecology and conservation is pivotal in advanced diving practices, making it a relevant consideration for divers looking to engage in responsible and educational collecting.
