1 00:00:00,000 --> 00:00:11,210 We are Martín, Eugenia, Carlota, and Gabriel, and we are going to talk about worms and mollusks. 2 00:00:11,210 --> 00:00:19,210 Worms. It is used to refer to the members of three different species. Flatworms, nematodes, and alleles. 3 00:00:19,210 --> 00:00:33,710 Worms, however, have common characteristics. They have bilateral symmetry. They tend to lie in humid climates. 4 00:00:33,710 --> 00:00:47,560 Flatworms are the simplest animals that have bilateral symmetry and tefalisation of the nervous system. 5 00:00:47,560 --> 00:01:01,229 The two most well-known groups of flatworms are tapeworms and canarians. 6 00:01:01,229 --> 00:01:10,230 Tapeworms are parasites that live in the intestines of many animals, including human beings. 7 00:01:10,230 --> 00:01:17,230 They do not have mouths because they are so resistant to the animals' intestines. 8 00:01:17,230 --> 00:01:21,230 They get diabetes, so they work. 9 00:01:21,230 --> 00:01:26,230 They are hermaphrodite and have the capacity to self-fertilize. 10 00:01:26,230 --> 00:01:28,230 Clannarium. 11 00:01:28,230 --> 00:01:35,230 These flatworms inhabit scenic climates and can be found in seas, rivers, and lakes. 12 00:01:35,230 --> 00:01:38,230 They work self-fertilizing. 13 00:01:38,230 --> 00:02:04,450 Some of them are parasites, others living independently of any host. 14 00:02:04,450 --> 00:02:07,450 They have the following characteristics. 15 00:02:07,450 --> 00:02:11,449 The digestive system, for example, and analgesic. 16 00:02:11,449 --> 00:02:17,449 These things, on the whole world, they are all benefits in fact, analgesic. 17 00:02:17,449 --> 00:02:20,449 They can help the person relaxing. 18 00:02:20,449 --> 00:02:29,449 They may lay eggs inside a cup with other pellets inside, therefore, they can... 19 00:02:29,449 --> 00:02:34,449 or they are in the... they are in cycle of the... 20 00:02:34,449 --> 00:02:39,449 Anelites are worms with segmented, cylindrical bodies. 21 00:02:39,449 --> 00:02:50,590 Some anelites, such as liches, can live in aquatic environments, and others, such as earthworms, live in semi-terrestrial environments. 22 00:02:50,590 --> 00:02:54,590 Anelites have the following characteristics. 23 00:02:54,590 --> 00:03:02,060 They have digestive tools, such as the mouth and anus. 24 00:03:02,060 --> 00:03:11,060 The majority of aquatic annelids feed on plankton and others, such as leeches, feed on blood of vertebrates. 25 00:03:12,060 --> 00:03:20,060 The biggest aquatic annelids live in deers and others carry out tenuous respiration. 26 00:03:20,060 --> 00:03:38,289 Mollusks are invertebrates that have soft bodies and bilateral symmetry. 27 00:03:38,289 --> 00:03:45,289 The majority of them are aquatic, although there are sea exceptions such as snails and slugs. 28 00:03:45,289 --> 00:03:58,289 Their bodies are made of an external layer or mantle that surrounds their internal organs. 29 00:03:58,289 --> 00:04:05,289 Many bodies have parts that are made of protective layers made of minerals. 30 00:04:05,289 --> 00:04:14,240 Some have a defining head which has a mouth and very well-developed sense organs. 31 00:04:14,240 --> 00:04:21,240 They have a mucus which they use to clean their mouth. 32 00:04:21,240 --> 00:04:24,240 Some mollusks do this to clean their mouth. 33 00:04:24,240 --> 00:04:27,240 Mollusks have a complete digestive tube. 34 00:04:27,240 --> 00:04:31,240 Many of them have an organ in their mouth called retula. 35 00:04:31,240 --> 00:04:35,240 Aquatic mollusks use dill's breath. 36 00:04:35,240 --> 00:04:42,550 Some mollusks have a tongue that works the same way as a mollusk. 37 00:04:42,550 --> 00:04:49,550 Monomotors are a group that is divided into beavers and cinnabars. 38 00:04:49,550 --> 00:04:54,550 Beavers are aquatic invertebrates that have two external cells, or beavers. 39 00:04:54,550 --> 00:05:01,930 They don't have an umbrella in their beavers because they are in their beavers. 40 00:05:01,930 --> 00:05:23,839 There were two deals. They wanted one of those in useful shape and they used it to fit in the tabletop. I think I might have invented it, but I can't determine if it was a safe sell. 41 00:05:23,839 --> 00:05:30,839 Gastropods have a defended head that has a mouth and four tickles. 42 00:05:30,839 --> 00:05:37,839 A ported gastropod is made with gills, and to restore one, use an organ that functions as a lanyard. 43 00:05:37,839 --> 00:05:43,839 These have a head and upper circulatory system. 44 00:05:43,839 --> 00:05:46,839 Teleports are automatic in very many ways. 45 00:05:46,839 --> 00:05:50,839 They move in the same direction as the head. 46 00:05:50,839 --> 00:05:54,839 Teleports have an independent head for all ports. 47 00:05:54,839 --> 00:06:01,839 Telapots have a well-defended head with primate-permined eyes. 48 00:06:01,839 --> 00:06:13,839 Next to it is a fruit which is dried in a set of tentacles with suction cups that help the animal to catch prey. 49 00:06:13,839 --> 00:06:29,050 They release water in order to move. 50 00:06:29,050 --> 00:06:37,949 Some theropods, such as sequins, release dark pigment squid ink. 51 00:06:40,389 --> 00:06:42,089 Thank you for listening.
