Species & System

The Sea Pig

The sea pig use the ring of their tentacles surrounding the mouth to feed and absorb nutrients. They are often found facing towards the currents. They're not social animals but scavenge the ocean floor for organic material. Sea pigs are like deposit feeder that get their food by removing organic particles form deep-sea mud. Using their sense of smell, they have a high preference for rich sources that have fell from the ocean's surface or for example, a dead while.

Aye-Aye (aka me in the morning :) 

Aye-aye are related to chimpanzee, apes and humans. They are nocturnal and stay curled up in a nest of leaves and branches. They find their food by listening for wood insect larvae moving under the tree barks. They have long fingers that help dig their food out, scooping out flesh of coconut and fruits.  Aye-aye are known for omen of ill luck. They are killed and hunted which make them endangered. Interesting fact, they were thought to be extinct in 1944 but were rediscovered in 1957 (

Yeti Crabs
Surprisingly, Yeti Crabs can be found in Antarctica which makes it interesting from their crab ancestors. They are skilled at adapting to their harsh lifestyle and since there's no sunlight, they've evolved another way to obtain energy: they "farm" their own food. The crab-like hair structures on their chest and arms attracts bacteria which is their main diet.  The question is how these crabs fit into hydrothermal-vent ecosystems is still a mystery. We still wonder how they are able to colonize other vents hundreds miles away in the Pacific Ocean.
