Does a slug have a tail?
Tail The part of a slug behind the mantle is called the ‘tail’. Foot The bottom side of a slug, which is flat, is called the ‘foot’. Like almost all gastropods, a slug moves by rhythmic waves of muscular contraction on the underside of its foot.
How many body parts does a slug have?
A snail’s body consists of five main parts – the head, the neck, the visceral hump, the tail and the foot. A slug has the same essential parts, except for the visceral hump or shell.
Do slugs have shells?
Some slugs have soft internal shells or prominent mantles, while others have nothing at all. Both slugs and snails have two upper tentacles that protrude from their foreheads.
What is a slugs mantle?
When frightened or not active, the slug retracts its head into the mantle for protection. The Mantle is a fleshy fold of skin which forms the Respiratory Cavity (sort of like a lung). (In some slug species there is a little piece of shell in the mantle!)
Why do my slugs have a hole on their side?
The pneumostome or breathing pore is a respiratory opening of the external body anatomy of an air-breathing land slug or land snail. It is a part of the respiratory system of gastropods. It is an opening in the right side of the mantle of a stylommatophoran snail or slug.
What kind of body does a slug have?
The slug body consists almost entirely of the foot(see below). The foot fringecircles the upper edge of the foot, and is marked by a continuous groove. They breathe through the pneumostome, which is the external opening of the lung on the right side of the body in most slugs, and the left in just a few.
Where are the sex organs located in a slug?
In a snail these openings must be outside the shell (nobody wants to poop in their own shell after all). Slugs are hermaphrodites with both male and female sex organs. A large respiratory pore, usually on the right side, called a pneumostome, leads to a single lung.
How does a slug move across the ground?
A slug or snail moves by rhythmic waves of muscular contraction on the underside of its foot. At the same time a layer of mucus is secreted, which helps smooth the slug’s path across the ground. Slugs and snails have two pairs of retractable tentacles on their head.
Which is part of the mantle does a slug have?
On one side (almost always the right hand side) of the mantle is a respiratory opening, which is easy to see when open, but difficult to see when closed. This opening is known as the pneumostome . Tail The part of a slug behind the mantle is called the ‘tail’.

What makes up the mantle of a slug?
The mantle is a flap of skin and tissue covering part of the body, and enclosing the lung. Mucus and slime is exuded by the foot and the body. The two may differ in colour and consistency. Slugs have 2 pairs of tentacles; the upper pair have eye spots at the tip.
A slug or snail moves by rhythmic waves of muscular contraction on the underside of its foot. At the same time a layer of mucus is secreted, which helps smooth the slug’s path across the ground. Slugs and snails have two pairs of retractable tentacles on their head. The upper, optic tentacles, have light-sensitive eyespots on the ends.
What kind of slug is brown with orange spots?
This is a relatively small slug tending to be around 3cm long when mature. Its is common in the north of England, lowlands of Scotland and parts of Ireland. The body is brown in colour, striped lengthwise and covered in tiny gold spots. Its underside is orange and it has orange body mucus.
