Evidence of an alarm signal in Ophiuroidea (Echinodermata)
Marine Biodiversity Records, 2009 Numerous marine species are able to assess predation risk through chemical signals, and this capacity is usually found among animals that experience intense predation and possess chemoreception ability, such as brittle stars. We investigated the occurrence of chemical alarm signals and responses in four species of brittle stars: Amphipholis squamata ...
