Why do seahorses swim upright?
Show answer & explanation
Answer: To hide among seagrass
To carry babies better — Wrong. While male seahorses carry babies in pouches, this isn't why they swim upright. The vertical posture evolved for camouflage among seagrass.
Their spine won't bend — Wrong. Seahorse spines are actually quite flexible. They swim upright as an evolutionary adaptation for camouflage in their seagrass habitat.
To hide among seagrass ✓ — Correct! Swimming vertically helps seahorses camouflage perfectly among seagrass and coral. Their body shape mimics swaying plants, making them nearly invisible to predators and prey alike!
