Mitochondrial DNA] is the DNA located in organelles called mitochondria, mtDNA is inherited from the mother (maternally inherited). Mechanisms for this include simple dilution (an egg contains 100,000 to 1,000,000 mtDNA molecules, whereas a sperm contains only 100 to 1000), degradation of sperm mtDNA in the fertilized egg, and, at least in a few organisms, failure of sperm mtDNA to enter the egg..

One heck of a unique Mother's Day card. You got your mitochondria from your mother in the egg cell from which you came. Mitochondria have their own DNA which can be used to trace your mother's mother's mother's mother's mother back through thousands of y

Cymothoa exigua, or the tongue-eating louse, is a parasitic crustacean that enters fish through the gills and then attaches itself at the base of the fish's tongue. It extracts blood from the fisht causing the tongue to atrophy from lack of blood. The parasite then replaces the fish's tongue by attaching itself to the muscles of the tongue stub. The fish is able to use the parasite just like a normal tongue. It appears that the parasite does not cause any other damage to the host fish.

Tongue-eating louse or Cymothoa exigua belonging to family Cymothoidae, enters fish (specifically, red snapper) through the gills, then attaches itself at the base of the fish’s tongue.
