This aquarium allows visitors to “dive” among the fascinating species populating the River without getting wet!
Common whelk, a scavenger
This necrophagous mollusc, also called the waved whelk or waved buccinum, feeds mainly on dead bodies of fish or crabs.
Using its siphon, a type of long, sensitive “tube”, it analyzes the substances found in the water and detects dead animals. It moves towards them using its strong foot. On arriving, it attaches to the carcass and patiently scrapes the surface with its toothed tongue.
Frilled anemone, underwater flower
Also called plumose anemone, this animal that looks like a flower, never moves from the surface it attaches to and feeds by catching the small organisms that swim within reach of its fine tentacles.
Its tentacles have tiny stingers that the anemone uses to paralyze its prey before swallowing it.
With individuals measuring more than 30 cm long, the frilled anemone is the biggest representative of its family in the Gulf of St Lawrence.
Basket star, underwater tree
The Latin name (Gorgonocephalus) of this ophiuroid, a cousin of the starfish, is said to come from the Gorgon, a creature in Greek mythology whose hair was made of living snakes. We can see the resemblance in the basket star’s arms with their many branches!
Settled on a rock facing the current, the basket star moves like a fan to trap passing plankton. When prey gets caught in one of its arms, it bends quickly to put it into its mouth filled with tiny teeth.
