The
Mangroves Have Crabs!!!
On today’s adventure we went to the through
kayaking through the beautiful mangrove forest ecosystem in Tavernier, Florida.
We had a great time and got to experience a ton of different species like the mangrove
tree crab (Aratus pisonii). These crabs
are so interesting to me personally because of the way they are able to move
around the mangrove forest through the trees and especially the way that they
are able to climb forwards and backward as well as hop/jump between trees.
They are mostly found in tropical
and subtropical areas from Florida to Brazil on the Atlantic Coast and from
Nicaragua to Peru on the Pacific Coast. The mangrove tree crab feed mostly on
the leaves on the red mangrove (R. mangle),
however, they prefer to feed on animal matter as much as they possibly can. Their
appearance is very beautiful with large eyes set apart from each other and the
carapace is wider at the top than at the bottom of the crab. The mangrove tree crab
is a fabulous brown and olive -green color that allows them to blend in with
their surrounds and tend to have red of purple markings around their pinchers. They
also have tufts of black hair and their legs are pointed at the end to aid them
in climbing through the mangroves. These little mangrove tree crabs are preyed
on by birds, terrestrial mammals, and larger crabs in the area and have to be
able to escape quickly in their environment or be able to hide effectively which
they are amazing at. They are naturally able to camouflage themselves but still
able to adapt and live in the harsh environment. They are definitely one of the
most interesting species within the mangrove ecosystem in my opinion.
We got to see so many
of these amazing mangrove tree crabs today everywhere that we look we were
either watching them climb through-out the trees or almost grabbing one by
accident as we reached for the branches on the mangroves to pull ourselves through
the forest in parts to skinny to paddle. It was an amazing experience and definitely
something I would want to do again and recommend to other
Its so amazing to know how they have those little hairs on their legs to help them climb the mangrooves and basically go everywhere. Another fact that you mentioned was how they are really good at camouflaging. It was definitely cool to see them that close and be in their environment.
ReplyDeleteDo they have any ecological significance?
