Here's why:
* Scavengers: These worms are scavengers, meaning they feed on dead organic matter.
* Decomposition process: They break down the tissues of the carcase, contributing to the natural cycle of decomposition.
* Nutrient cycling: Their activities release nutrients back into the ecosystem, benefiting other organisms.
While these worms are essential to the process, they are not the only ones:
* Other scavengers: Various other animals, like sharks, crabs, and even other worms, contribute to the decomposition of a dolphin carcase.
* Bacteria: Bacteria are key players in the breakdown of organic matter.
It's important to note: The process of decomposition is complex and involves a variety of organisms. Marine worms play a significant role but are not the only actors in this natural cycle.
