The class Gastropoda or the gastropods, also previously known as gasteropods, or univalves, and more commonly known as snails and slugs, are the most diversified class in the phylum of mollusks, with (60,000-75,000) to 80,000 known living species.

There are 409 recent families of gastropods, but fossils have been classified as showing 202 further families This class of animals is second only to insects in its number of known species.

The class is striking in its extraordinary diversification of habitats. Representatives live in gardens, in woodland, in deserts, and on mountains; in small ditches, great rivers and lakes; in estuaries, mudflats, the rocky intertidal, the sandy subtidal, in the abyssal depths of the oceans, and numerous other ecological niches, including parasitic ones.

This class includes very very large numbers of species of marine snails and sea slugs, as well as freshwater snails and freshwater limpets, and the terrestrial snails and slugs.

Although the name “snail” can be, and often is, applied to all the members of this class, very commonly this word is restricted to those species which have an external shell large enough that the soft parts can withdraw completely into it. Those gastropods without a shell, and those which have only a very reduced or internal shell, are often known as slugs.

The marine shelled species of gastropod include edible species such as abalone, conches, periwinkles, whelks, and numerous other sea snails which have coiled seashells. There are also a number of families of species such as all the various limpets, where the shell is coiled only in the larval stage, and is a simple conical structure after that.

Above all of my knowledge about it, i have question for you all.

In the middles of 2008, i was researching about Bioindicator Poluttion of Tanjung Emas Harbour Semarang. The research using “trawl” to collect data of macrozoobenthos that living here. The gasropoda is one of them which i was collect.

For my “undergraduate” make some species being in unidentification, can you all help me to identified those? It’s open for you who know the link to share my “identify”. Thanks Before.

p.s. the unidentified species below

INTERAKSI MANUSIA DENGAN ALAM: Pocong Pemikat Gurita

16:03 Wed 07-01-2009, ketika itu saya menonton Program Trans7 “Jejak Petualang” tentunya saya bersama teman-teman MDC (Marine Diving Club – Ilmu Kelautan UNDIP) tepatnya para penghuni Basecamp. Pada episode itu membahas tentang Suku Bajo yang berada di daerah Toja Una-una. Bicara soal suku ini, kita semua tahu bahwa Suku Bajo merupakan “Suku Bahari“, yang setiap tempat (pesisir) di seluruh pelosok Tanah Air bakal ditemukan adanya suku yang punya trik khusus dalam menangkap gurita ini. Seperti saya juga pernah beberapa kali mengunjungi (saat itu dalam rangka monitoring ekosistem karang) Kepulauan Karimunjawa, jepara Jawa Tengah juga terdapat Suku tersebut, bayangkan jarak antara Toja Una-una (Sulawesi) dengan Karimunjawa (Jawa tengah). Kembali ke Suku Bajo, suku ini pada umunnya memiliki ciri-ciri: rumah (tempat tinggal) berbentuk rumah panggung tepat di atas air laut, terdapat “parking zone” di depan rumah (buat kapal tentunya), serta Trik khusus mereka dalam berburu gurita.
