Whilst at
Saudi Aramco Half Moon Bay beach recently we saw a few Blubber Jellyfish. Half
Moon Bay is a shallow and warm coastal area near Dhahran in the Eastern
Province of Saudi Arabia where the species is often found in swarms. Blubber
Jellyfish have a translucent sub-hemispherical bell up to 35 centimetres across
and eight conical arms and are quite common in the shallow coastal waters southwards
to Abu Dhabi in the United Arab Emirates at certain times of the year, mainly
the spring and summer. During the day the Blubber Jellyfish swims close to the
water surface to obtain sunlight that it converts to energy. They come in
various colours from translucent greyish white, like the ones at Half Moon Bay,
to blue-green or even bright blue and reddish.
