Cover: This juvenile Apteronotus leptorhynchus, or brown ghost knifefish, belongs to one of approximately 200 species of South American gymnotiform weakly electric fishes. These animals use an active electrosense for foraging at night in often turbid waters as well as for communication. The total energetic cost of their electric behaviour, including generation and sensing of the electric field, is estimated to be about 30% of routine metabolic rate (Salazar et al., pp. 2459−2468). The articles in this special issue review the remarkable recent contributions of research on electric fishes to energetics and many other areas of biology.

Celebrating Open Access
In the field: an interview with Glenn Tattersall
Glenn Tattersall talks about his experiences using a thermal imaging camera in South Africa, the Galapagos Islands, Scotland and Brazil.
Flexible wings take the effort out of swimming for diving penguins
Penguins depend on the flexibility of their wings for their effortless agility.
Communication with self, friends and foes in active-sensing animals
Te Jones, Kathryne Allen and Cynthia Moss review the constraints on echo- and electro-locating animals such as weakly electric fish, bats and odontocetes, which are subject to signal interference and eavesdropping that compromise information transmission.
