| Named Used as Valid | Cetorhinus maximus |
| Comment | The discovery of basking sharks lacking functional gill rakers during autumn and winter in north-west European waters suggests a resting, non-feeding, demersal stage. Deleted from the Ecology remarks, because Ref. 50200 suggests feeding in winter. |
