Device for verifying suitable habitat of benthonic animals in inland lake water area

The invention discloses an inland lake water area benthonic animal suitable habitat verification device, and relates to the technical field of benthonic animal monitoring. Compared with a previous benthonic animal collecting device, the benthonic animal collecting device solves the problems that in the prior art, the requirement for collected benthonic animals is high, and the comprehensiveness and integrity of collected data cannot be guaranteed; in order to solve the problems in the prior art that the existing benthonic animals are large in size, and the placing and collecting process of the device disturbs an ecological system in a large range, so that a water body becomes turbid, and investigation and research progress are very unfavorable, different survival matrixes are provided for the benthonic animals based on a plurality of conical grooves and artificial matrix plates divided by different materials; benthos moving on the bottom layer of the water bottom and some fixed benthos can be considered at th
