Trivia question of the week:
The Answer to last week's question:
|
Q: What fish is among the only animal species on Earth in which the male bears the unborn young? |
A: Male seahorses are equipped with a brood pouch on their ventral, or front-facing, side. When mating, the female deposits her eggs into his pouch, and the male fertilizes them internally. He carries the eggs in his pouch until they hatch, then releases fully formed, miniature seahorses into the water.

Previous Trivia questions:
|
Q: Where did the green turtle get its name?
|
|
A: The color of a green sea turtle's fat is green; therefore, it is called the green turtle.
|
|
Q: How is the age of a fish determined?
|
|
A: Mainly by two methods: Growth "rings" on scales, and/or ringlike structures found in otoliths (small bones of the inner ear), are examined and counted. The rings correspond to seasonal changes in the environment and can be compared to the annual rings of tree trunks. A series of fine rings are laid down in scales for each year of life in summer, the rings grow faster and have relatively wide separations; in winter, slower growth is indicated by narrow separations between rings. Each pair of rings indicates one year. Because scale rings are sometimes influenced by other factors, scientists often use otoliths, whose ringlike structures also indicate years of life.
