Invertebrate Animals | Educational Video for Kids



Hi friends, welcome to a new happy learning video… today we are going to learn about the invertebrate animals You all know that the animals are divided
into two big groups, the vertebrates that have an internal skeleton formed by bones
and the invertebrates that have no bones. All the invertebrates are oviparous, and we
classify them in 6 big groups: Sponges, jellyfish, corals, worms, mollusks, echinoderms and arthropods The sponges are aquatic animals, that are
sac shaped and their body is full of pores. It is very easy to remember this group because
many times we use them in the shower for our personal hygiene. Yes, many of the sponges
we use in the shower are invertebrate animals. The jellyfish are invertebrate animals that
live in the ocean. Their bodies are gelatinous and have tentacles. The truth is that when
they appear in the beach it is very annoying because their tentacles have small venomous
stingers that produce very unpleasant bites. Corals are tiny marine animals that produce
limestone residue, which give rise to beautiful shapes. Do you know this animal? Exactly, it’s a
worm. Worms are soft and long invertebrate animals that move by dragging their body in
the ground, because they have no feet. They can be aquatic or terrestrial. There are some
worms that can be harmful and that is why we must be careful with them. Can you see this snail? Well snails form part
of the mollusk group. Mollusks have a soft body, without legs and
can also be aquatic or terrestrial. Some, like this snail, this clam and mussels,
protect their soft body with shells, but there are other mollusks that don’t have a shell
to protect themselves like slugs or octopuses. The echinoderms are exclusively aquatic animals.
Their bodies have calcareous plates that form a shell. Some echinoderms are balloon shaped and are
covered in spikes that they use to defend themselves, like sea urchins.
Others are star shaped, and are of course called starfish. The arthropods are the most abundant animals
on the earth. Of every 100 animals that exist, 80 are arthropods. These invertebrate animals have their body
covered by an external skeleton called a cuticle. The most common way to classify the arthropods
is by the number of legs they have. This way we can classify them in four big groups. Arthropods with 6 legs. In this group insects
like ants and flies are present. Arthropods with 8 legs, where for example
the arachnids like spiders and scorpions are. Arthropods with 10 legs include the crustaceans,
like crabs and lobster. Arthropods with more than 10 legs like this
centipede that as you can see has much more than 100 legs are called myriapods. Well now you know a bit more about the invertebrates. Bye friends, and don’t forget to subscribe

  1. Hey your wrong you put Caterpillars on myriapods but u said centipede actually centipede and millipede is myriapods but Caterpillar is not its a insect larva (butterfly larva).

  2. Thanks to this, I won the national science quiz in the Philippines. This is really a big help to me. Thank you
