Close Encounters in the Tidal Zone

As much as we enjoy wildlife, it’s seldom that we have an opportunity to hold live specimens in our hands.  Most wild creatures want to put as much distance between us and them as possible, and that’s how it should be.   However, opportunities to get up close and personal with wildlife are possible along Nova Scotia’s seashore in the intertidal zone.  Marine animals such as crabs and starfish are easily caught and respond well to gentle handling.

The starfish at left was found in the salt marsh.  Its underside reveals gel-like feelers that glisten in the sunlight as they move.  Live, juicy starfish are enjoyed by seagulls who can spot them underwater clinging to rocks.

Though a bit more difficult to catch, live crabs are very animated and deeper in color than the dried ones found higher up the beach.  Up close they look like little aliens.  They too are eaten by seagulls.

To those who are willing to get really up close, offshore waters offer even more wonders.

Live sand dollars are nothing like the bone dry tests we may sometimes find on the beach.  Their five point star design is just barely discernible beneath their deep purple fur-like covering of cilia.  Beds of these can be found by scuba divers in the subtidal zone, a wonder hidden from the view of beachcombers.  Sand dollars are preyed upon by starfish, snails and skates.

After handling these delicate marine creatures, it’s best to quickly place them back where they were found as they are unable to survive out of the water for long.  Such close encounters should be kept as brief as possible, unless of course you’re a seagull looking for a meal.

I’m hungry Dolores. Should we get fast food or see what’s slow in the marsh?

Beyond the Shore

Beyond Nova Scotia’s ocean shore lies the world of inner space.  This marvelous world is seen by few except divers, who brave our cold waters for just a glimpse of its wildlife inhabitants.  The rest of us only see evidence of undersea life when it is washed ashore or edible forms appear on our dinnerplate.  Yet, how far these experiences remove us from the pulse of life beneath the surface of the waves.

The best way to observe a fish is to become a fish.

The spiny sculpin, shown at top, is an odd-looking fish that can survive out of water for hours at a time as long as it stays wet.  Another bottom dweller is the flounder shown below.  Amazingly, one of the flounder’s eyes gradually drifts from one side of its body to the other.  The body of the fish eventually turns on its side, where both of its eyes come to rest on ‘top.’ 

 

Crustaceans, such as this spider crab, are also found on the sea floor, scavenging for food.

Hermit crabs search the sea floor for empty shells that they may use to protect their vulnerable bodies from predators.  They don’t possess the hard exoskeleton common to most true crabs.

The seafood section in Nova Scotia’s grocery stores often hold live lobsters in a tank.  The trapped  lobster, shown above, seems destined for such a place.  Like many crustaceans, it possesses the magical ability to regrow its asymmetrical claws.

Among the most attractive creatures to be found off our coasts are the carnivorous sea anemones, which look deceptively like plants.
