Movement - The blobfish primarily floats around and swallows crustaceans as they pass by.
Respiration - The blobfish's respiratory system uses a process called countercurrent flow to obtain oxygen because it does not have lungs. Countercurrent flow occurs when the water and blood within the body of the fish go in opposite directions across the gills to diffuse as much oxygen into the blood as possible.
Sensitivity - Blobfish has no sensitivity and it is not sensitive to things that can affect (influence) it because ultimately blobfish are just slightly sentient lumps of FAT.
Growth - The blobfish, whose scientific name is Psychrolutes Marcus, grows to as much as a foot long and contains almost no muscle at all. With no muscle, the fish are not edible to humans, as you would be eating mostly a big blob of gelatin.
Reproduction - The blobfish opens its big mouth, and food filters on through. The fish reproduce by laying thousands of eggs in nests. Several females often nest near one another, and they hover over their eggs until they hatch.
Excretion - The blobfish has a very small digestive system compared to most species of fish; however, the process of breaking down food in the body is very similar. Finally, the food is excreted through the anus at the bottom of the fish.
Nutrition - Their diet consists of small crustaceans like crabs, sea urchins, and shellfish. These goodies are sucked into the blobfish's mouth as it floats along. Lacking both bones and teeth, they do not actively hunt.
