Zebra shark at centre of 'virgin birth' mystery
A lone zebra shark in a Dubai aquarium has prompted scientific interest after laying eggs for the fourth year in a row which hatch into healthy offspring.
Zebedee, who lives in the Burj aAl Arab hotel's aquarium, has never had access to a male shark but that has not stopped her producing numerous live offspring.
Philip Hampsheir reports from Dubai.
