LAB SKILL 11 Collection and PreservationInvertebrate Species I. Basic theory Animals occupy almost every environment on earth, but the most abundant members of most phyllum are aquatic species. Oceans, which were likely home to a large number of animal phyllum. Freshwater fauna is abundant, but not as rich in diversity as marine fauna. Invertebrate animals include Phylum porifera, coelenterates, platyhelmintes, nemathelmintes, annelids, molluscs, echinoderms and arthropods. To better understand each phyllum, we can see directly in the field how it forms and how it lives in nature. This field lecture in the Invertebrate Zoology course, apart from seeing these invertebrate animals directly, is also used to increase the collection of animals that do not have backbones in the laboratory, as well as increase students' understanding of the material they have studied in class. II. Tools and materials Tool : 1. 4 20 clear plastic jam bottles/ 2. jars measuring 1 kg Rubber 3. bands 4. Stationery 5. Gloves Material : 1. Formalin 5% 2. Alcohol 70% III. How it works 1.Prepare the tools that will be used for field practicum 2.Walk to the specimen collection location carefully as a group. 3.Take animal specimens from the sea carefully. 4.Place the specimens found in a plastic jar and add formalin and 70% alcohol (for large specimens such as the gastropod class, annelids and for the phylum arthropods, put them in a plastic bag and provide an air cavity). 5.Give a specific label (species name, place and date of collection, name of collector) and record the characteristics on the unknown specimen. 6.Identify the animal specimens found 7.Group the animals and arrange the classification in taxonomy.
