Leech has 32 brains. Leech‘s internal structure is divided into 32 separate segments, each of which has its own brain. Leeches have been around for millions of years, but they have only recently been recognized as an important part of the ecosystem. They are a major food source for many animals, including fish, birds, amphibians, reptiles and mammals. In fact, leeches are so important that they are considered an endangered species in some countries.

What animal always forgets?
Chimpanzees, bees, baboons, hamsters, and seals have the worst memories. Only a few animals pass with good results when it comes to learning new information, as the animal’s memory may differ from species to species. The ability to learn new things is one of the most important aspects of memory. It is the ability of an animal to remember information that it has already learned. The same is true for humans.
When we learn something new, we often remember it better than when we learned it the first time. However, this is not always the case. Some animals, such as dogs, can remember things that they have learned many times before. In other cases, the animal may have a very poor memory for the information it learned previously. These animals are often referred to as “retrograde” or “repetitive” learners.

What animal has 25000 teeth?
Even though their mouths are no larger than the head of a pin, snails can have over 25,000 teeth over the course of their lives. Larvae can live for up to 10 years in the wild, and can grow to be as large as an adult. They can be found in all types of habitats, but are most common in tropical and subtropical areas.
What animal never dies?
The ‘immortal’ jellyfish, turritopsis dohrnii, is the only one of its kind. These small, transparent animals can turn back time by reverting to an earlier stage of their life cycle when they hang out in oceans around the world.
In a new study published in the journal Nature Communications, a team of researchers from the University of California, Santa Cruz, and the National Oceanic and Atmospheric Administration (NOAA) have found that the tiny creatures can go back in time to a point in their evolutionary history when they were just a few millimeters in length.
This means that they can live for hundreds of millions of years, or even longer, depending on how long they’ve been exposed to the elements and how much time they spend on the surface of the ocean.
“This is the first time that we’ve found evidence that these animals are able to change their genetic make-up in response to environmental changes,” said lead author and UCSC professor of biological oceanography and marine biology, Dr. David Schlegel, in a press release.
