Field Notes
Description:
The adult bears a hard, thin calcareous shell 25–40 mm in diameter and 25–35 mm high, with four or five whorls. The shell is somewhat variable in color and shade but is generally dark brown or chestnut with yellow stripes, flecks, or streaks.
General, the body of a gastropod consists of four main parts: the visceral mass, mantle, head and foot. The head is highly developed and bilaterally symmetrical. It contains a pair (sometimes two) of tentacles, a mouth, and eyes. The eyes are often located on the tips of the tentacles. The mouth contains an important device called the radula that functions in food processing, but has also adapted to serve many different purposes. The radula may contain up to a quarter of a million individual teeth that grind up food before it is passed to an esophagus and stomach.
It moves at a top speed of ~1.3 centimetres per second.
It feeds on numerous types of fruit trees, vegetable crops, garden flowers, and cereals
Habitat:
Gastropods live just about everywhere on Earth - salt water, fresh water, and on land. In the ocean, they live in both shallow, intertidal areas and the deep sea, favour moist environments.
Notes:
They're in my backyard in Sammakorn Village. I found them when I was taking a bird photograph(that bird is real blur= =), fortunately, I found these two snails (and a dead snail nearby). I thought they're trying to harm my plants but I didn't mind them so I left them...
