Nature can be surprising, and sometimes a little unsettling, especially when animals behave in ways that seem hard for us to understand. One such example is self-cannibalism, highlighting a behaviour where some species eat parts of their own bodies. It might be a snake swallowing its shed skin or an animal chewing off a badly injured limb. Although this sounds disturbing, it can actually be practical. In nature, food is never guaranteed, and removing evidence of injury can help animals stay hidden from predators. Scientists have seen this behaviour in frogs, snakes, crustaceans, lizards, and octopuses, usually linked to hunger, stress, or survival instincts rather than choice. Here are five animals known for this unusual behaviour.<\/p>\n

Animals that eat themselves<\/keyword>: From snakes to lizards
<\/h2>\n<\/p>\n

<\/p>\n

Frogs
<\/h3>\n<\/p>\n

<\/p>\n

\n
\"Frogs\"<\/div>\n<\/div>\n

Frogs are kind of neat in this way. Green treefrogs, for example, routinely shed their skin and then eat it. Experts say it\u2019s called dermatophagy. Sounds fancy. Basically, it helps them recycle proteins and minerals, keep their skin healthy, and even hide their scent from predators.Some scientists think it might also help frogs build immunity against pathogens. They sometimes go full-on cannibal and eat other frogs. <\/p>\n

Snakes
<\/h3>\n<\/p>\n

<\/p>\n

\n
\"Snakes\"<\/div>\n<\/div>\n

Snakes sometimes do the strangest things. It\u2019s called ouroboros. It\u2019s when a snake bites its own tail. Reportedly, it happens mostly in captivity. When stressed, their brains seem to misfire. They think their own tail is food.Captive snakes like garter snakes, corn snakes, and California kingsnakes sometimes even eat their shed skin from which they get tiny nutrients from it. <\/p>\n

Crustaceans
<\/h3>\n<\/p>\n

<\/p>\n

\n
\"Crustaceans\"<\/div>\n<\/div>\n

Crustaceans are experts in recycling. Crabs, lobsters, and shrimp often eat their own exoskeletons after molting. It gives them back calcium and minerals, which they\u2019d otherwise lose. And some are downright cannibalistic. Soft-bodied crabs might attack a molting neighbour and gobble it up. <\/p>\n

Lizards<\/h3>\n<\/p>\n

<\/p>\n

\n
\"Lizards\"<\/div>\n<\/div>\n

Many lizards can drop their tails to escape predators. Fat-tailed geckos, leopard geckos, green anoles; they all do it. And once the tail is gone, they often eat it.Experts say it\u2019s to recover fat, nutrients, and calcium. Apparently, it can be up to 20% of their stored energy. Watching them do it is weird practically. That tail isn\u2019t wasted; it becomes dinner later.<\/p>\n

Octopuses
<\/h3>\n<\/p>\n

<\/p>\n

\n
\"Octopuses\"<\/div>\n<\/div>\n

Octopuses have the most dramatic stories. Octopus vulgaris and similar species sometimes bite or amputate their own arms in captivity. Stress, weird neurological conditions, or escaping predators can trigger it.And females octopuses after laying eggs, hormonal changes might push them toward self-harm. <\/p>\n

Some animals tend to eat their own body parts. Here are the creepy reasons:<\/p>\n
