Polychaetes from Scottish Waters: Family Nereidae Pt. 3: A Guide to Identification (Polychaetes from Scottish waters: a guide to identification)
Both acidic and alkaline environments suppress nematocyst firing. Thus, if you come out of the surf with a jellyfish tentacle on you, douse it with urine (acidic) or baking soda (al- kaline) to reduce the impact.

The persisting or- gans lie within an open blastocoelom, partially parti- tioned by mesentery-like ligaments. PHYLUM ACANTHOCEPHALA The phylum Acanthocephala is divided into three class- es on the basis of the arrangement of proboscis hooks, the nature of the epidermal nuclei, spination patterns on the trunk, and nature of the reproductive organs , e.g. The Tragedy of Hamlet, Prince of Denmark read The Tragedy of Hamlet, Prince of Denmark book. Mollusc nephridia are rather large and saclike, and their walls are greatly folded. In many forms, affer- ent and efferent nephridial vessels carry hemolymph to and from the kidney tissues (Figure 20.38). Often a short bladder is present just before the nephridiopore online.

Evisceration is the expulsion by mus- cular action of part or all of the digestive tract and some- times other organs, including the respiratory trees and gonads. In some forms (e.g., Holothuria) all of these structures are expelled following rupture of the hindgut region Microscopic Anatomy of Invertebrates. Volumes 6A & 6B: Mollusca II .

The former is derived from the second maxillae; the origin of the latter is unclear. †The hypopharynx is considered by most workers to be an inde- pendent outgrowth of the body wall and not a true appendage.

When cI is present it activates its own synthesis and blocks transcription of cro. When cI is inactivated, transcription of cro can occur, resulting in the lytic cycle. The cI protein combines with the operator, Or.

These larvae are so different from adults that they are often given separate vernacular names; for example, butterfly larvae are called caterpillars, fly larvae mag- gots, and beetle larvae grubs.

During tor- sion, the mantle cavity and anus are moved from a pos- terior to a more anterior position, somewhat above and behind the head. Visceral structures and incipient or- gans that were on the right side of the larval animal end up on the left side of the adult. The gut is twisted into a U-shape, and when the longitudinal nerve cords con- necting the pleural to the visceral ganglia develop, they are crossed rather like a figure eight Funniest Minibeasts (Leapfrog read here

It is not yet known if these different cate- gories represent actual lineages of homologous struc- tures, but it is interesting to note that the two groups of taxa roughly parallel the two distinct lines of evolution- arily related taxa known as deuterostomes and proto- stomes (see Chapters 4 and 24) Select Narrations of Holy read epub
