Question: what is the most brightly coulored thing in the ocean?

Even though their name doesn’t sound very appealing, I would say the sea slugs are some of the most colourful and beautiful creatures in the ocean. They can be very brightly coloured – with orange, blue, purple, yellow, pink, fluorescent green… They are simply stunning! They also come in all sort s of patterns (spots, stripes, dashes), and with extra frills, bumps and hairs. You just have to look them up online, they are unbelievable.
