Razors: what they are and how they are captured

Razors: what they are and how they are captured

The razor is a marine bivalve mollusk. It lives on the seabed buried in the sand, where it digs deep vertical holes of up to 70 centimetres and is able to do so at one centimetre per second. The tops of these holes are shaped like eight.

The knives are unisexual animals of exogenous reproduction, reason why the fertilization takes place in the waters of the sea.

Their way of moving is by means of impulses. They can be propelled up to half a metre thanks to the pressure it exerts when throwing water in the form of a jet.

They feed on plankton, and it does so through gills. Their meat is highly appreciated and can be eaten fresh and, of course, canned.

Fishing methods

 

There are several methods to catch this type of shellfish. One of them is with salt. The salt is spread through the entrance area of the galleries where they are found. This makes the animals emerge to the surface and can be easily collected in the sand.

Specifically, divers, as a rule, do so with a bottle or shower with highly concentrated salt water and spread it on a bank of razor blades. As brine is denser than seawater, the solution goes down through the holes. The increase in salinity within the gallery causes the mollusk to come to the surface of the sediment, at which point it is captured.

Another method of capture is through a rod with a conical piece at the tip. The rod is introduced up to the bottom, obviously it goes through the knife, but on one side, without killing it, and then the rod is raised upwards, extracting the animal with it, remaining a prisoner in the conical piece.
