Ecology Summary - Balaenoptera brydei

Language:

Ecology of Balaenoptera brydei

Main Ref.	Rice, D.W., 1998
Remarks	Inhabits tropical and warm temperate waters in major oceans between approximately 40°N and 40°S. They are generally restricted to waters warmer than 20°C. Feeds on copepods, euphausiids, and fishes (Ref. 79555). In Madeira, they can be found alone or in groups of two to five between June and November. Foraging includes both searching for prey and prey capture. Lunges are considered feeding dives while other deep dives were foraging dives without prey capture (Ref. 114954).
