Fishes Parents Cares - dr inż. Aleksandra Kwaśniak-Płacheta (Tropical), Dr Dariusz Danel (Zakład Antropologii PAN)
Aquarium hobbyists have a possibility to observe proliferation in numerous fish species in their tanks. Parental care observed in some of the species is its most spectacular aspect that triggers specific emotions. Despite the fact that most fish species don’t take care of their offspring, the cases of a male, a female or both parents taking care of their fry have been observed. Such behavioural pattern is most often associated with Cichlidae family. However, parents taking care of their offspring are to be found among many other fish species. The article’s authors try to explain how parental care in fish evolved.

Exotarium in Lublin - Bartłomiej Gorzkowski
Exotarium in Lublin is an essential part of the animal shelter and has been operating for 1,5 years now. It becomes a home for various animals – tiny scorpions, tarantulas, a variety of lizards, frogs, turtles and numerous species of snakes (including huge Indian pythons and regal pythons). These animals are refugees from reptile farms, unwanted live gifts, “live toys”, animals that got sick and started to cause trouble or animals whose requirements exceeded their owners’ abilities – there’s no general rule for all the cases. Nevertheless, they have one thing in common: a vast majority of them is in a critical state. If it wasn’t for the voluntaries’ commitment and veterinarians’ hard work, they wouldn’t be saved.
