Coelenterates (pronounce sill-enter-rate)
Examples include Jellyfish
The worm that couldn’t work on the building site because she didn’t have a backbone is also a keen athlete. She enters a sponsored triathlon, but there’s a silly entry rate (coelenterate) – the worm has to pay an entry fee of £100 and raise at least £3,000 in promised sponsorship before it can take part! As soon as she put her name down her only ‘leg’ felt like jelly (jellyfish).
