Gaze Into the Disappearing Mouth of the Hydra is an art installation by artist Alicja Kwade. It consists of a large mirror that reflects a video of a hydra, a tiny freshwater organism that can regenerate itself when cut. The video shows the hydra consuming a small piece of meat, which disappears as it is digested. The installation is meant to explore the concept of time and the cyclical nature of life and death. It also highlights the incredible regenerative abilities of the hydra, which has been studied by scientists for its potential to help humans regenerate damaged tissue.

HowStuffWorks Now: The Hydra’s Mouth is a Hungry Wound HowStuffWorks
In a real-life encounter between members of the Hydra and Cyclops genera, the Hydra typically emerges victorious. Using its poisonous tentacles, the Hydra stuns its prey before ripping open its own body to create a gaping mouth. It engulfs the Cyclops and then seals the wound seamlessly.
The Hydra vulgaris has two glowing tissue layers.

The University of California, San Diego conducted a study on the Hydra’s feeding strategy. By engineering transgenic Hydra vulgaris polyps with fluorescent proteins, researchers were able to observe the skin cells as they warped and deformed, opening the creature’s mouth the same way a human iris opens.
The Hydra’s asexual budding and ageless physiology make it a fascinating creature, but its small size (less than half an inch) is a blessing. Watch the video above to learn more about this shape-shifting and slightly terrifying animal.
FAQ
1. What is the Hydra?
The Hydra is a genus of freshwater animals with tentacles called cnidarians. They are often referred to as “freshwater polyps” and are known for their ability to regenerate lost body parts. The most common species is the Hydra vulgaris.
2. How does the Hydra feed?
The Hydra feeds by using its tentacles to capture small aquatic animals, such as crustaceans and larvae. The tentacles are lined with stinging cells called nematocysts, which paralyze the prey. The Hydra then uses its mouth to ingest the food.
3. What is the disappearing mouth of the Hydra?
The disappearing mouth of the Hydra is a unique feature where the mouth can retract into the body. This allows the Hydra to protect itself from predators and also helps with digestion. When the Hydra is ready to feed, the mouth extends outwards to capture prey.
4. How does the Hydra reproduce?
The Hydra can reproduce both sexually and asexually. In asexual reproduction, the Hydra can simply grow a new body part, which will eventually develop into a new individual. In sexual reproduction, the Hydra releases eggs or sperm into the water, which then fuse to form a zygote. The zygote will then develop into a new individual.
5. What is the lifespan of a Hydra?
The Hydra has a relatively short lifespan of a few weeks to a few months, depending on the species and environmental conditions. However, they are able to reproduce quickly and continuously, allowing them to maintain a population in their habitat.
6. What is the significance of studying the Hydra?
The Hydra is an important model organism in biology due to its ability to regenerate and its simple body structure. It has been used in research for over a century to study topics such as cell differentiation, aging, and cancer. The Hydra has also been used as a tool for environmental monitoring, as it is sensitive to pollutants in the water.
7. Are there any threats to the Hydra?
The Hydra is not currently considered to be threatened or endangered. However, as with many aquatic animals, pollution and habitat destruction can have negative impacts on their populations. Additionally, the introduction of non-native species can disrupt the balance of ecosystems where the Hydra lives.
8. Can the Hydra be kept as a pet?
The Hydra is not a common pet due to its unique feeding requirements and short lifespan. It is also illegal to keep Hydra in some countries without a permit. However, they can be kept in laboratory settings for research purposes.
