Two sperm whales were recently spotted performing a spectacular deep dive above the Ikaria Trench in the Aegean Sea, off the coast of Greece, according to a report by the environmental organization Archipelagos Institute of Marine Conservation.
The sighting was captured by the scientific team aboard Triton, the institute’s research vessel, during an ongoing marine mammal study in the region. The mission involved monitoring whale behavior, documenting deep-diving activity, and collecting data on species presence and environmental conditions in one of the most ecologically significant areas of the Aegean Sea.

The Ikaria Trench, a steep underwater canyon differereaching depths of around 1,400 meters (almost 4,600 ft), is considered one of the most biodiverse marine zones in the Mediterranean. This deep-sea region, located between the Greek islands of Ikaria, Chios, and Samos, reaches depths of over 1,100 meters (3,600 ft) and is part of an important migratory route for large marine mammals in the northeast Mediterranean.
For over 25 years, researchers have documented at least seven species of marine mammals in the area, making it a vital habitat for species conservation. “The data we are collecting in this challenging yet remarkable sea is crucial, and we look forward to sharing the results of this long-term research effort soon,” the Archipelagos team shared on social media, posting a striking image of the two whales moments before their descent.
About sperm whales (Physeter macrocephalus)
The sperm whale is the largest toothed whale on Earth, with adults reaching lengths of 16 to 18 meters (52-59 ft) and weighing up to 50 tons. Known for their distinctive block-shaped heads and exceptional deep-diving ability, sperm whales can descend over 1,000 meters (around 3,280 ft) in search of squid, their primary food source.
These marine giants play a key role in ocean ecosystems by regulating the marine food web and nutrient cycles. Typically found in deep offshore waters, the recent sighting of sperm whales above the Ikaria Trench off the coast of Greece was not only breathtaking but also of significant scientific interest, especially given the species’ endangered status in the Mediterranean.
