The Calypso Deep, located in the Matapan–Vavilov Deep, is roughly deep and is the deepest point in the Mediterranean Sea.
The Hellenic trench region is an ecosystem to sperm whales and other aquatic life and has been used by marine biologists to study the behaviour of various aquatic species.
This is the trench where several earthquakes, including the 365 Crete earthquake, occurred.
