no, they are mammals no mammals have exoskeletons
Lugworms do not bite in the way that many animals do; they lack teeth or a biting mechanism. Instead, they feed by ingesting sediment and organic matter from the ocean floor. If handled, lugworms may wriggle or squirm, but this is a defensive behavior rather than an aggressive one. Thus, while they can be unsettling, they pose no threat of biting.
Yes, all insects have exoskeletons.
No, the don't. For example, crabs have exoskeletons.
Lugworms reproduce by releasing eggs and sperm into the water, where external fertilization takes place. The fertilized eggs develop into larvae, which eventually settle into the sediment and grow into adult lugworms.
Lugworms are annelids, so they therefore belong to the annelida phylum.
Insects have exoskeletons for both protection and structural support.
No, insects have exoskeletons, which are hard, external skeletons that provide support and protection. These exoskeletons are made of a material called chitin.
No.
Yes, coral does have exoskeletons made of calcium carbonate. These exoskeletons provide structure and support for the coral polyps, which are tiny organisms that secrete the calcium carbonate to build the coral reefs. Over time, these exoskeletons accumulate and form the large coral reef structures we see in the ocean.
Flatworms are carnivores, herbivores and scavengers.
Yes, they do have exoskeletons. Exoskeletons are hard outer shells that protect and support the body.
