Snails and slugs eat with a jaw and a flexible band of thousands of microscopic teeth, called a radula. Snails and slugs As in other molluscs, the circulatory system of gastropods is open, with the fluid, or haemolymph, flowing through sinuses and bathing the tissues directly. The haemolymph typically contains haemocyanin, and is blue in colour. › Circulatory_system_of_gastropods radula The radula (UK: /ˈrædjʊlə/, US: /ˈrædʒʊlə/; plural radulae or radulas) is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. › wiki › Radula
Does a snail have a tooth?
Answer: yes, And between 1,000 and 12,000 of them.

Instead, snails have got a specialized food processing organ, common to all molluscs: A rasping tongue or radula. Using it, snails are not able to bite of their food, but to rasp it down.

Who has the strongest teeth ever?
The hardest substance ever discovered in nature is the tooth of a limpet (sea snail). They have a tensile strength between 3 and 6.5 gigapascals, breaking the previous record of spider silk at 1.3 GPa. Limpets need super hard teeth in order to chew the algae off of hard rocks.

What's tougher than a diamond?

Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.

Do snails bleed?
Bleeding;haemolymph; snails; molluscs; Achatina spp. The blood of pulmonate snails [Mollusca: Gastropoda) is usually referred to as haemolymph: it contains the copper-based respiratory pigment haemocyanin (Morton 1958). Withdrawal of haemolymph from live snails may be necessary for a variety of reasons.
Can snails draw blood?
Snails can't bite or chew on you like a dog, but they can run their toothed tongue over your skin which might feel like a bite. A snail can't break your skin or draw blood like this, and it isn't trying to attack you. It just thinks your hand is food and wants to taste it to make sure.
