Crayfish have compound eyes, similar to many insects. These eyes are on stalks on the top of their head and allows them to see what is going on above them when they are in the bottom of a body of water.

Structures

Yes. Actually have a couple.

Crustaceans' teeth are primarily made of a hard mineral called calcium carbonate. This mineral is often found in the form of calcite or aragonite, which provides strength and rigidity to their feeding structures. Additionally, some crustaceans may have teeth composed of chitin, a flexible organic compound that contributes to the overall structure and function of their mandibles. Together, these materials allow crustaceans to effectively process their food.

any microbial research in prawns?

Sponges only stay in one spot because they are sessile. Sessile means that they are attached to a substrate and cannot move.

Hope this helps!

Yerrp they eat crayfish !!

hi, yea they are right they do breathe with gills. but its a little more complicated than than lol

Class Malacostraca Order Decopoda

Being largely aquatic, most larger crustaceans breathe via gills. Their gas exchange system is closed (cf. the open system of insects), and the oxygen that diffuses through the gills is either transported in simple solution in the haemolymph, or bound to blood pigments such as haemoglobin or haemocyanin.

Crayfish gills are located between the carapace (the exoskeleton of the cephalothorax) and the lateral body wall, in the branchial chamber.

Oxygen and carbon dioxide are exchanged between the blood and water across the gill surface as water is circulated through the branchial chamber by the beating of the gill bailer on the second maxilla.

Barnacles

An alien ship arrived over Johannesburg, South Africa more than twenty years ago. Discovered aboard the ship were numerous malnourished alien-beings referred to as Prawns, due to their Prawn-like appearance (racism has never been particularly inventive). With the world's eyes on the South African government, the mostly-peaceful aliens were segregated from the human population and held in an area designated District 9. When these alien procreate they produce what is known as a "baby prawn".

There are few pictures of baby prawns available on the internet but you can refer to this picture of an adult, just picture it smaller: http://cache.gawker.com/assets/stills/districtnineplot_io9.flv.jpg
