RESEARCH: Social spiders help each other to catch their prey

f&m Leave a comment

There are many animal species that hunt in packs to kills their prey, especially when the prey is large. Examples of animals that hunt in packs include wolves, lions, dogs, hyenas, and ants.

Pack hunting is also called cooperative hunting because each individual animal in the pack cooperates with the rest of the pack for the same purpose. 

A new 2021 research study shows that some spider species also practice cooperative hunting to help each other to catch their prey. Researchers at the University of Toulouse in France observed two colonies of a social spider species called Anelosimus eximius. The researchers copied the actions of prey entering a spider web – they created vibrations in different parts of the webs – and filmed the responses of the spiders.

RESEARCH: Albatrosses divorce more often when ocean waters are warm

f&m Leave a comment

Research scientists think that albatrosses divorce and seek new partners when conditions are harsher than usual, reported Science News in November 2021. The research was documented in the Proceedings of the Royal Society, Series B.

The albatross is a large seabird in the Diomedeidae family. The albatross is a monogamous bird, which means that it stays with the same partner for life. However, when ocean waters are warmer than average, more of the albatross birds break up and look for a new partner, says a recent study.

The Plate Coral is a colony of organisms, each with a separate mouth. It is shaped like a plate with a round, flat body, which is raised a little in the centre where the mouth is. It is covered with short tentacles, less than 2 centimetres (less than an inch) in height. It can be a variety of colours, from brownish to yellow, red, blue, or orange.

European Paper Wasp

f&m Leave a comment

The European Paper Wasp (Polistes dominula) is a hymenopteran insect, a winged insect related to bees, wasps, and hornets. It is a vespid and a polist wasp in the Polistini tribe. It is a social wasp. It is also known as the Common Poet. 

The European Paper Wasp has a slender yellow and black body and long yellowish-orange legs. It drags its legs behind it when it is flying, because its legs are long. Its narrow wings are orange with dark tips. It has large eyes. Its antennae are yellowish-orange with club-shaped tips. 

It has a venomous stinger at the end of its abdomen. It can sting multiple times because the stinger stays in the body (the stinger of bees comes out of the body when the bee stings an animal, so it can only sting once).

Fallacy: All Bees Live in Hives

f&m Leave a comment

A fallacy is something that is not true.

All bees live in hives is a fallacy.

Do all bees live in hives? No, not all bees live in hives. There are social bees and solitary bees.

A colony of bees—many thousands of bees—are social bees that live together in a hive. The Bumblebee and the Honeybee (or Honey Bee) are social bees, living in colonies, and living in hives.

However, solitary bees do not live in hives. 

Most bee species are, in fact, solitary bees.

The Violescent Sea-Whip (Paramuricea clavata) is a marine (saltwater) soft coral in the Plexauridae family. It is also known as the Purple Gorgonin. It is an animal, not a plant. 

The Violescent Sea-Whip is red or reddish-purple, but it may be partly yellow. It grows in the soil at the bottom of the ocean. It has branching arms, like a whip, that form a fan shape. The stem and branches are made from a protein called gorgonin, that forms a bony skeleton. Polyps protrude from the skeleton. The polyps have a central mouth disc with eight tentacles around the circular disc.
