The changes to your growing embryo are not quite as drastic this week as they've been in the last few weeks.
Growth is now focused on your wee manatee's head, which is developing and growing much more rapidly than the rest of their tiny body. This is because their amazing brain is undergoing some very critical changes in order to effectively regulate their heart rate, blood circulation, and other vital functions.
As for the rest of their tiny body, what were only limb buds last week have grown into wee limb flippers this week and their sea-creature tail is even more visible.
Amazingly, within five short weeks of existence, your hard-working miniature manatee is already sporting the rudimentary forms of their liver, pancreas, lungs, stomach and nasal pits while their heart is increasing its circulatory capacity.
And if you were wondering about size, your sea-monkey has grown to an impressive 5 mm in length. Growing like this only happens once in a lifetime!
