The Whale Fall Process
When a whale dies, the carcass sinks to the ocean floor
Carcass provides food and energy for organisms
Unique communities develop around the whale fall and have high species richness
Whale fall goes through 3 stages

Mobile-Scavenger Stage
Stage begins with large scavengers such as:
Hagfish
Sleeper Sharks
Rattails

Mobile-Scavenger Stage
Followed by smaller scavengers such as:
Crabs
Scuds
Ends with calenoid copepods

Enrichment-Opportunist Stage
Enriched sediment around carcass hosts organisms such as:
Bristle Worms
Hooded Shrimp
Snails

Sulphophilic Stage
Organisms derive energy from bacteria:
Mussels
Tube Worms
Other organisms feed on bacterial mats:
Limpets
Bristle Worms
