Well, it's that time of year again, time to renew the web hosting. And for those of you that don't know, that has become a lot more expensive than it used to be. Fifty dollars a year is now several hundred. Not to mention the price of domain names has gone up ten-fold.
And I just found out that the nice folks at PayPal disabled all my Support buttons, and I never got a notice (although that may be my fault.) In any case, it is all working again now, so if you would like to make a small donation to help defray these costs, it would be greatly appreciated.
Many insects which are terrestrial as adults have aquatic larvae. Notorious among these are mosquitos. Most aquatic insects have aquatic larvae.
Caddisfly Nymph Trichoptera
Caddisfly larva build tube-like cases of sand, sticks, leaves, or other material.
Stonefly Nymph Neophasganophora spp. larva to 2"
Dragonfly - Adult & Nymph Anax spp. larva to 1 " adult to 3"
The clumsy-looking Dragonfly larva is actually a fierce predator, with protrusible jaws like something out of "Alien". Adults are often seen buzzing around ponds and lakes.
Dragonflies are anything but tame - this one was blown out to sea and exhausted
A fish is defined as a limbless aquatic vertebrate animal with fins and internal gills. There are three living classes of fish:
Primitive jawless fishes - class Agnatha
Cartilaginous fishes - class Chondrichthyes
Bony fishes - class Osteichthyes
These groups, although quite different from one another anatomically, have certain common features related to their common evolutionary origins or to their aquatic way of life. Fish were the earliest vertebrates, and presumably evolved from a group of aquatic lower chordates; the terrestrial vertebrates evolved from fishes.
