The large reniform eyes of the reptant, tube-dwelling decapod Nephrops norvegicus are described in detail. Optically these reflecting superposition compound eyes are a little unusual in that they are laterally flattened, a feature that may enhance th...

Laboratory-Based Observations of Behaviour in Northern Krill (Meganyctiphanes norvegica Sars) (2010)
Book Chapter
Gaten, E., Wiese, K., & Johnson, M. L. (2010). Laboratory-Based Observations of Behaviour in Northern Krill (Meganyctiphanes norvegica Sars). In Advances in Marine Biology, 231-253. Elsevier. doi:10.1016/B978-0-12-381308-4.00008-X

The behaviour of planktonic animals remains poorly understood due to the difficulty of observing them in situ without influencing their behaviour. Here we review experiments on the behavioural responses of Northern krill, Meganyctiphanes norvegica (a...
