1 00:00:00,000 --> 00:00:16,120 3, 2, 1, video. We are going to talk about invertebrates, about arthropods, of two types, crustaceans and arachnids. 2 00:00:16,399 --> 00:00:20,039 They are oviparous, that means that they reproduce by eggs. 3 00:00:20,399 --> 00:00:26,160 The diet of the crustaceans is omnivorous, that means that they eat all types of food, like us. 4 00:00:26,160 --> 00:00:30,640 And the diet of the arachnids is carnivorous, that eat meat. 5 00:00:31,300 --> 00:00:32,060 The characteristics. 6 00:00:32,399 --> 00:00:37,939 The arachnid's characteristics is that it has leaky antennas and wings. 7 00:00:38,659 --> 00:00:44,740 Be equipped with four pairs of legs and have the body divided into the thorax and abdomen. 8 00:00:45,380 --> 00:00:54,380 The characteristics of crustaceans eat that they are aquatic and inhabit all deep and in different environments. 9 00:00:56,159 --> 00:01:05,159 There are two examples, so the first one is an example about their production and metamorphosis. 10 00:01:05,159 --> 00:01:12,159 So first it starts out as an egg, which has been laid by a butterfly. 11 00:01:12,159 --> 00:01:20,159 Then they hatch from the eggs and transform into caterpillars or larvae, 12 00:01:20,159 --> 00:01:25,159 which then grows and eats to, 13 00:01:26,599 --> 00:01:28,920 it grows and molds its exoskeleton 14 00:01:28,920 --> 00:01:30,859 until it becomes a pupa. 15 00:01:32,400 --> 00:01:35,439 The pupa then undergoes a profound transformation 16 00:01:35,439 --> 00:01:38,459 and becomes an adult butterfly, which is this one. 17 00:01:40,159 --> 00:01:43,379 And then the process goes all over again 18 00:01:43,379 --> 00:01:46,540 until the butterfly is laying new eggs. 19 00:01:46,540 --> 00:01:58,579 Another example is an example about arachnids and here in this whole part is the cephalotorax. 20 00:01:58,579 --> 00:02:09,180 These two are the tselicerae and on this part it's the abdomen of the spider. 21 00:02:09,180 --> 00:02:16,139 The conclusion of this video is that we are talking about arthropods, which have lots 22 00:02:16,139 --> 00:02:23,180 of types, but there are two, which are crustaceans and arachnids, which are the ones we're talking 23 00:02:23,180 --> 00:02:29,560 about, that their diet is both omnivores and carnivores, and they have very different 24 00:02:29,560 --> 00:02:37,360 characteristics. And this video is made by Lucia, Claudia, and Pablo, and Lucia.
