How to catch Heart Cockle
Use the Shellfish Tongs. The exact approach depends on the creature’s category and, for shore-dwellers, its species type.
- Equip the Shellfish Tongs and search the intertidal zone along the beach.
- Shellfish are mostly stationary. The Pearl Oyster is the notable exception and can move.
First catch: the creature is added to the Omnidex. Offer it to Mors at the Omni-Gallery to put it on display and unlock its Omnipedia entry.
Where and when to find it

Intertidal Zone · Corculum cardissa
The heart cockle's shell is an incredibly symmetrical heart shape. The special structure was designed to house symbiotic algae.
The algae provide nutrients for the heart cockle through photosynthesis, while the cockle offers a safe haven inside its body in a mutually beneficial symbiosis.
