2  Banana slug are yellow some may be green brown and white. Some slugs have black stop to make them look almost black solid. Slugs use two pairs of tentacles to sense their environment. They produce up to 75 translucent eggs, which are laid in a log or on leaves. The Pacific banana slug is the second- largest species of terrestrial slug in the world; growing up to 25 centimeters (9.8 in) long the largest is limax cinereoniger of Europe, which can reach 30 centimeters (12 in) in length.

3  Ducks and geese and other animals eat banana slugs. and also some birds and beetles are slug predators. Frogs, toads, snakes, hedgehogs, Salamanders, eastern box turtles, humans. Eat banana slugs and slugs. Salt is harmful to all slugs.Frogstoads snakeshedgehogsSalamanderseastern box turtleshumans

4  Many banana slug species play an important ecosystem role by eating dead leaves, fungus, and decaying vegetable material. Other species eat parts of living plants. Some slugs are predators, eating other slugs and snails, or earthworms.leavesfungus predatorsearthworms

5  The mucus of some species is mildly poisonous. Most slugs are harmless to humans and to their interests, but a small number of species are great pests of agriculture and horticulture.

6  They can destroy foliage faster than plants can grow, thus killing even fairly large plants. They also feed on fruits and vegetables prior to harvest, making holes in the crop, which can make individual items unsuitable to sell for aesthetic reasons and which can make the crop more vulnerable to rot and disease.

7  Augustus A. Gould scientific name in 1851. August is the one who named the banana slug and he named it that because for it bright yellow and then other people found out there is other colors of the banana slug.

8  Encountered on the ground or within creek banks and tree roots during the dry summer months and banana slugs ate other small plants which are redwood competitors for space, water, light, and nutrients. They are usually deposited in clumps of 30 eggs that will hatch in 3-8 weeks their eggs are about 15-20 mm and they are colorless eggs.

9  In order to hatch, the eggs need sustained moisture, mild temperatures, and a good hiding place. Once the eggs have hatched, it is up to the baby banana slugs to find their own food for survival.

10  Banana slugs are found primarily in coastal rainforests, where the damp environs and abundance of decaying leaves and mushrooms provide ideal habitats for slugs. Slugs breathe through their skin and a single lung, and both organs must be damp in order to function.

11  Banana slugs get their name because these large slugs resemble bananas, at least the yellow variants. Banana slugs, like all slugs, are hermaphrodites. Banana slugs do not rank high on any predator’s list of desired foods due to their slime.

12  There are all cans of banana slugs there are green, yellow the most common gray and white some banana slugs have dot that make them look black.
