Sea Raven

Sea Raven

Hemitripterus americanus

Size
to 25" and 7 lbs.

Description:
The fleshy tabs around the head and ragged-looking dorsal fin are identifying characteristics of Scorpionfish like the Sea Raven. The eye is also very strange looking. These fishes prefer cooler waters and disappear when it warms up. Tropical and Pacific relatives including the introduced Lionfish have poisonous spines, but our species is harmless. Some people eat them, but I find them to be among the most interesting and obliging photo subjects in our waters.

We seldom consider the water we dive in, yet it is a fascinating subject in its own right.

Basic Chemistry

Water is an odorless, tasteless, transparent liquid that is colorless in small amounts but exhibits a bluish tinge in large quantities. It is the most familiar and abundant liquid on earth. In solid form ( ice ) and liquid form it covers about 70% of the earth's surface. It is present in varying amounts in the atmosphere. Most of the living tissue of a human being is made up of water; it constitutes about 92% of blood plasma, about 80% of muscle tissue, about 60% of red blood cells, and over half of most other tissues. It is also an important component of the tissues of most other living things.
