Ew, slime! If a bigger animal tries to eat a hagfish, the hagfish makes lots of slime. The slime chokes the bigger animal and the hagfish escapes. Have a look at this video of hagfish slime. Wait until the end when it's all over the person's hands! Slugs. You've probably seen the slime trails that slugs make on a night. This slimy mucus helps stop the slug from slipping on vertical surfaces. It can also help slugs to find a mate. Slugs cover their body in a different type of slime, which stops the slug drying out. It also makes the slug less tasty to predators.

Why Are Fish So Slimy? Some fish form cocoons out of their slime. Parrotfish, for example, produce a mucus tent that completely envelopes them, which may protect them from attack. Slime can also regulate, on a molecular level, the exchanges that are made between the fish's body and the surrounding seawater.

- They all obtain energy by decomposing organic materials, and as a result, are important for recycling nutrients. The plasmodium is the feeding stage of the slime mold. It moves much like an amoeba, slowly sneaking along decaying organic material. It moves at a rate of 1 in (2.5 cm) per hour, engulfing microorganisms.

- In general however, slime molds are characterized by the production of relatively large, single-celled, multinucleate bodies called plasmodia (singular = plasmodium). Plasmodia are the feeding stages of slime molds, and they are frequently seen on lawns, small plants, mulch, and decaying wood in late summer. Slime molds are frequently observed when they form large colonies on mulch around trees or shrubs.

Food preservation in food preservation: Bacteria. ...bacteria contaminate a food substrate, it takes some time before they start growing. This lag phase is the period when the bacteria are adjusting to the environment. Following the lag phase is the log phase, in which population grows in a logarithmic fashion. As the population grows, the bacteria consume available nutrients and produce waste products.
