Eden's whales look very similar to Bryde's whales. Sometimes they might also be confused with large Minke whales when seen at sea. The body color is a dark, smoky blue-gray with a cream or light blue-gray underside. The head is V-shaped with a longitudinal ridge that is flanked by two auxiliary ridges on either side. The dorsal fin is taller and more pointed at the tip than in Bryde's whales; the curvature is similar to the Minke whale.
Eden's whales are inquisitive, and may suddenly appear beside boats. While travelling, the Eden’s whale may be happy to swim alongside a vessel, turning sideways to have a better look. However, they rarely allow vessels to come close but may approach a vessel when the engine is off.
Sightings have been confirmed at the coast off Sri Lanka. Due to its similarities with Bryde's and Minke whales it is not clear yet how many former sightings can be confirmed.
Social system/Group size
Possibly boat traffic, noise and entanglement in fishing gear.
The Eden's whale is also known as the "smaller form" of a Bryde's whale. The taxonomic status and the relationships between these species remain complex and poorly understood.
