Aquarists at the SEA LIFE London Aquarium have hoodwinked the public with a decidedly fishy new marine species - a family of fish finger fish. A new display, featuring models of fish fingers with fins and tails billed as bona-fide aquatic life has startled guests over the last week - BUT has fooled as many as it has amused, report the team behind the tongue in cheek hoax. The gag was prompted by a survey in which 1 in 10* respondents said fish fingers were real fish and although it is intended to raise a smile there is a serious underlying message.
