Within the barriers, non-covalent interactions will predominate, including electrostatic and electrodyn-amic interactions complemented by hydrogen bonding. These non-covalent properties of the interface will determ

The same holds for the integument, where investigations have focussed largely on a few oligochaetes (see Richards 1977 a, 1978, Jamieson 1981).

Among the oligochaetes, chaetae are fewer and less diverse (Fig. 1 A) but also demonstrate a variety of taxonomically useful patterns (Brinkhurst 1982). Annelid chaetae have been discussed recently by

For some of the smaller groups of invertebrates little information is available, as often only a few electron micrographs are to be found in the literature; 978-3-642-51595-8978-3-642-51593-4

The latter protect themselves against potentially destructive attack from enzymes and antibodies by a structural device — the inert cuticle, which moults to bring about a renewal of the surface. Tapeworms, in contrast, are anenteric and must necessaril
