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.


tides

Shore diving is very much dependant on the tide. Tidal inlets and rivers will flow with the tide, such that a river may even flow upstream for a time when the tide is incoming. Normal river currents are far too strong to swim against, and will simply sweep away a loaded diver. Many inlets have time restrictions for divers, so you will have to take the local laws and the tide tables into account to work out a good dive time.

However, there are two times when the currents drop to near zero. Those are dead high tide, and dead low tide. Of the two, dead high tide is usually better, simply because there is more water, and it is cleaner ocean water rather than silty river water. You will get about a half-hour window on either side of dead high tide during which you can either drift in the weak current or swim against it. After that, you'd better get out.
