The Deep is excited to announce video evidence of a baby zebra shark growing inside a recently laid egg, from our female zebra shark.
Following recent mating behaviour, The Deep?s Curator was delighted to find a zebra shark egg in our Endless Oceans display which had a yolk inside, leading to very careful observation from the team to see if it was fertile.
Katy Duke, Curator at The Deep continues: ?Our zebra sharks have been laying eggs for a while, but until they are fully mature, they tend to only be ?practice? eggs with nothing inside. ?This is the first year we have had an egg complete with a yolk and this recently filmed footage confirmed our suspicions that we had a baby shark growing inside.
?The baby is only visible via a method called ?candling? where we shine a torch behind the egg underwater. This allows us to see inside the dark brown casing and you can clearly see a baby attached to the yolk moving around.
?Although we are still a long way from hatching, we are hopeful that things will progress well. Zebra sharks eggs take around 6 or 7 months to hatch which would take us into early next year.?
The Deep is home to a male and female zebra shark, and now mature they are expected to lay eggs each year. Male sharks grow up to 1.8m in length with females coming in at 1.7m.
