How many antennas do crayfish have

In fact, the word "arthropoda" means "joint-foot". Crayfish have two main body areas: the cephalothorax, which consists of the head and upper body, and then the abdomen, which is clearly segmented. You can find appendages on both areas. Focus on the head, you may notice small appendages around the mouth.

On the photo below you can see the topmost maxillipeds. These appendages help the crayfish manipulate food. They are strong and can break the hard shells of many aquatic animals. In short, crayfish can bring new life to your classroom.

Crayfish are crustaceans. Their appearance is bizarre-they are festooned with a bewildering array of walking legs, pincers , and other appendages for eating, feeling, and attending to other crayfish business. Two pairs of small antennae the antennae and antennules are specialized chemical detectors used in foraging and finding a mate.

The antennae project on either side of the tip of the rostrum, which is a beak-like projection at the front of the head. What are crayfish pincers called? The crayfish has 8 jointed walking legs, a segmented body, 2 pairs of sensory antennae, and compound eyes. It has 2 large pincers or claws called chelipeds. If a crayfish loses a leg, the leg will regenerate regrow. The head and thorax are fused, forming the cephalothorax. How can you tell if a crayfish is male or female?

The first set of "baby" legs: On the male, the first set is covered in a hard shell; on the female, they're thin and feathery. What do Crayfish eat? Crayfish, being omnivorous, can eat anything that they find. Their diet consists of vegetables like frozen peas, carrots, and even plants like Java moss. They also eat shrimp, meat, fish, insects that accidentally fall into the tank, sinking pellets, table scrap, etc. How do crayfish reproduce?

Crayfish mate in the early spring and females carry the fertilized, developing eggs inside their bodies for 4 to 6 weeks. Crayfish are usually colored in earth tones of muted greens and browns. The body has three primary sections: the cephalothorax the fused head and thorax , which is entirely encased by a single shell; the carapace, a sixsegmented abdomen; and a five-sectioned, fan-shaped tail, the telson.

Five pairs of strong, jointed, armored legs pereiopods on the cephalothorax are used for walking and digging. The first pair of legs, known as the chelipeds, end in large pincers chelae , which are used for defense and food gathering.
