Knefastia Altenai
''Knefastia altenai'' is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies. Description Knefastia altenai is a species of marine gastropod mollusk in the family Pseudomelatomidae. These snails are commonly found in coastal waters and prefer sandy or muddy substrates off Colombia. They have an elongated shell with an average length of 57.4 mm, with intricate patterns and vibrant colors.
