📋 Key Takeaway

Marine scientists have discovered that the endangered black teatfish sea cucumber can live over 100 years, indicating that their populations recover more slowly than previously believed. This finding, led by Dr. Sven Uthicke from the Australian Institute of Marine Science, has significant implications for commercial fishing regulations. The study highlights the need for careful management of marine resources, which is relevant for Iran's fishing industry.

Marine scientists have been amazed to discover an endangered sea cucumber can live for decades, with some animals living more than 100 years, in a first-of-its-kind genetic mark-recapture study. Australian Institute of Marine Science (AIMS) Senior Principal Research Scientist Dr. Sven Uthicke said the findings suggested black teatfish sea cucumber populations recover much more slowly than previously thought and that this had implications for commercial fishery catch limits.
