How do you care for triops?

User Avatar

Asked by Wiki User

If you got a triops kit, it should have food in it. I don't remember how often you have to feed it, so check the instuctions. You will also need a desk lamp or something over it, and that needs to be turned on every day. You should also regularly clean out their tank if it's one of those small ones that doesn't have a filter.

What are disadvantages of radial symmetry?

User Avatar

Asked by Wiki User

The main disadvantage to radial symmetry (eyes on the side of the head as opposed to the front) is that vision is mostly two dimensional. A creature with eyes on the sides of its head can only focus both its eyes on an object if the object is directly in front of it. This makes the range (distance) and comparative size of other creatures and objects harder to judge. It also makes discerning camoflaged creatures from their surroundings much more difficult. For raptors (birds of prey), radial symmetry presents a lot of problems when hunting. These are overcome by various other natural systems such as improved spatial awareness and superlative hearing.

Do bears eat crayfish?

User Avatar

Asked by Wiki User

It would be very difficult for a grizzly bear to eat a lobster. Most grizzly bears fish in rivers and creeks. I suppose a grizzly could wander near an ocean, but it would be very difficult for them to find a lobster that is a bottom-dweller. They also would be unsure how to open the lobster to get to the meat.
