“…Directional override was reduced to chance only after the elimination of both vision and LL suggesting that either modality alone is sufficient for the expression of this property of the escape. This observation is consistent with reports that the LL can function independently to provide blind fish with sufficient directional information to navigate around nearby objects (Burt de Perera, 2004;von Campenhausen et al, 1981).…”

“…The LL is typically understood as an organ that detects the presence of nearby objects (von Campenhausen et al, 1981). We therefore asked whether this system plays a functional role in the directional overrides observed in the escapes that occur when the fish is close to the wall of the tank (Fig.6).…”

“…Nestler et al (2012) suggest that fish use flow deformations downstream of within-channel features to generate a 'hydrodynamic image' that allows them to navigate topographically complex environments. For example, behavioural studies with blind cave fish (Astyanax hubbsi) have demonstrated their ability to navigate obstacles from changing pressure distributions, despite their blindness (von Campenhausen et al 1981;Abdel-Latif 1990;Sharma et al 2009). Consequently, at least some species of fish appear able to use meso-scale (metres) hydrodynamic features to interpret their environment, in addition to fine-scale (cm) turbulent bursts that may indicate the presence of prey or predators.…”
