Crustaceans molt, regrow limbs, and sometimes just die for no obvious reason.
In this section, I cover what’s normal (bubble-blowing crabs, stress signs) and what’s not. Bacterial infections, failed molts, parasites – I explain how to spot problems early and what actually works as treatment. Prevention starts with water quality and diet.
Today I am going to be exploring all things relating to crustacean’s pain and neuroscience! So, do crabs, hermit crabs, crayfish or shrimp feel pain? This is a very tricky problem, especially for those of us who are working with these model organisms or even
Today I am going to talk about the internal structure of the crayfish. This is the second part of the article on crayfish anatomy (the first was about the external structure). Basically, crayfish internal anatomy includes the following systems: the circulatory system, the respiratory system,
Even though the anatomy of crayfish varies from species to species, and yet there are basic physical characteristics that are identical among all crayfish species, from the Dwarf Mexican crayfish (Cambarellus patzcuarensis) to the giant the Tasmanian giant freshwater crayfish (Astacopsis gouldi). As a typical
Like all crustaceans, crayfish have external exoskeletons (shells) that limit their growth. Therefore, to grow in size, they have to shed their old shells. It may sound like a simple process but it is not! Actually, it would be no exaggeration to say that molting
Molting is a dangerous undertaking for hermit crabs and most other invertebrates. According to the statistics, in nature, almost 90 % of their deaths are related to unsuccessful molting. To make it even worse, sometimes people get confused and unable to tell if your hermit crab
Hermit crabs are nice little pets that can live for up to 20 – 30 years with you if you take care of them properly. Despite their small size, and the fact they probably look easy enough to look after, they require a great deal
The hobby of keeping aquarium shrimp has been steadily increasing in popularity for years. Shrimp make a great addition to home aquariums and as an added bonus, they came in a wide variety of shapes, colors, and sizes. And while the care regimen for shrimp
