How does a cockle escape predators?

How does a cockle escape predators?

Behaviorally, cockles live buried in sediment, whereas scallops either are free-living and will swim into the water column to avoid a predator, or in some cases live attached by a byssus to a substrate. The mantle has three apertures (inhalant, exhalant, and pedal) for siphoning water and for the foot to protrude.

How do cockles defend themselves?

Heart cockles don’t live as deep in the sand as most other clams do. Instead they rely on their thick, ribbed shell to protect them from predators. They also have sensory organs along their mantle (visible in the link above) that can detect approaching predators, and they use their foot to drag themselves to safety.

What do cockles feed on?

phytoplankton
Like other bivalves, cockles don’t have heads. To eat, they pump water across their gills and catch phytoplankton (tiny plants). They then move the phytoplankton into their mouths. This process is called filter feeding.

How do cockles breathe?

They draw water into one [they inhale through the inhalant siphon] and pump it out of the other [they exhale through the exhalant siphon]. Cockles are buried in the seafloor with their siphons opening just above the mud or sand.

What do cockles need to survive?

Cockles need food and oxygen to survive. They have adaptations to carry out gas exchange and feed. They have gills that carry out gas exchange underwater when the tide is in. The gills do two jobs – take in oxygen and filter out fine food particles.
