Glass eels are the transparent, juvenile stage of the
eel's life cycle, typically found in coastal and
estuarine waters as they migrate from the ocean to
freshwater rivers. Their see-through bodies help them
avoid predators, making them well-adapted for
survival during this vulnerable phase. Highly valued
in some cultures as a delicacy, they are also
important in ecological and commercial contexts. Due
to overfishing and habitat loss, glass eel
populations are now closely monitored in many
regions.
