Why is tropical water so blue?

Most of the Caribbean has that turquoise blue color because of the shallow depths. The deeper the ocean, the deeper the shade of blue because the sunlight can’t reach the bottom. When the water is deeper, it absorbs all the sun rays, creating a darker shade. So the more shallow the water, the lighter the blue.

What attracts fish the most?

Bottom dwellers, such as catfish, are well known for being attracted to baits that smell bad. Bass, the most sought after of all inland game fish, depend primarily on sight and sound to locate prey. Their sense of smell acts as the third leg of the stool when they feed near the bottom or in murky water.

In very deep water, almost all of the sun’s rays are absorbed by the water itself due to the lack of sediment and the lower amount of organic matter (like algae and jellyfish), and thus the blue appears to be darker.
