They will also choose live shrimp over dead ones, even when there are more available dead prey. Other revelations exposed a riskassessment strategy based on their appetite – choosing larger numbers of smaller prey when they were less hungry. These new findings now place that “calamari” alongside primates and human infants when it comes to number sense. CALLING TIME ON BLUEFIN DIVERS DISCOVER A NEW SPECIES AT 150 METRES A new species of groppo – a bright pink and yellow little fish that vaguely resembles an anthias – has been discovered by divers off the coast of Luzon, in the Batangas Province, Philippines.
