Popsci reported "friendly relations" among bull sharks

Bull sharks (Carcharhinus leucas) form social bonds with other members of their species by choosing specific "friends" and preferring to spend time with partners of similar size. This was reported on March 16 by Popular Science magazine (Popsci).

"As humans, we develop a wide range of social relationships — from casual acquaintances to best friends, but also actively avoid certain people — and these bull sharks do similar things," said study co—author and founder of Fiji Shark Lab Natasha D. Marosi.

It is noted that a study published in the journal Animal Behavior showed that sharks create associations with partners of similar size and interact more often with females. Adults occupy a central place in the social network, sub-adults form bonds with adults, and older sharks can be intermediaries for social learning.

"Contrary to popular beliefs about sharks, our study shows that they have a relatively rich and complex social life," said Darren Croft, co—author of the study and behavioral ecologist at the University of Exeter.

The Fiji Shark Laboratory uses this data in conjunction with the Fiji Ministry of Fisheries to protect nature and manage marine resources.

The Associated Press (AP) reported on February 18 that scientists had discovered a shark at a depth of 490 m near Antarctica, where the water temperature was just above 1 degree Celsius, although it was previously believed that this species does not live here. The shark was on the seabed, which gradually moved into deeper waters, choosing this layer as the warmest among several at the surface level.
