Lined Seahorse

Seahorse

Hippocampus erectus

Size: to 6"

Habitat: Weedy protected shore waters.

Notes:

Look for Seahorses in still weedy areas, where they cling to plants and objects with their prehensile tails. Color and body form are highly variable, as these masters of camouflage adapt to their surroundings. Strays may be found at sea, or even washed up on the beach.

Locomotion is accomplished by fluttering the dorsal and pectoral fins, and they are extremely weak swimmers, utterly unable to buck a current. Males have a brood pouch where they incubate the eggs, then give birth to fully-formed miniature copies of themselves. Seahorses feed on plankton, which they suck up with their tubular snouts, making a distinct popping sound. They are tolerant of brackish water, but not fresh.

Echinoderms ( literally "spiny skins" ) are among the strangest animals on the planet. They start out as bilaterally symmetric larvae but grow into a 5-way body symmetry as adults. Some species show six, seven, or even higher levels of symmetry. Worm-like Sea Cucumbers have re-evolved a bilateral body plan over the underlying 5-way plan. Because of certain developmental traits, it is felt that despite their strangeness, echinoderms are actually more closely related to chordates than any other group.
