Hello Dr Godzilla, pleased to meet you.
Could you provide the source where you get this
data (about the poison of the barracuda)? I think that is very interesting.
Also, it will be interesting if you and Pckts
put some data (size, behavior, etc.) and images to give us a better idea of the
I will provide the blue shark data, since I back it
"Blue sharks are light-bodied with long pectoral fins
. Like many other sharks, blue sharks are countershaded
the top of the body is deep blue, lighter on the sides, and the
underside is white. The male blue shark commonly grows to 1.82 to 2.82 m
(6.0 to 9.3 ft) at maturity, whereas the larger females commonly grow
to 2.2 to 3.3 m (7.2 to 10.8 ft) at maturity.
Large specimens can grow to 3.8 m (12 ft) long. Occasionally, an
outsized blue shark is reported, with one widely printed claim of a
length of 6.1 m (20 ft), but no shark even approaching this has been
confirmed in this species.
The Blue Shark is fairly elongated
and slender in build and typically weighs from 27 to 55 kg (60 to
121 lb) in males and from 93 to 182 kg (205 to 401 lb) in large females.
Occasionally, a female in excess of 3 m (9.8 ft) will weigh over 204 kg
(450 lb). The heaviest reported weight for the species was 391 kg
The blue shark is also ectothermic
"Although often observed cruising slowly and sluggishly the blue shark is capable of rapid movement if it is excited or feeding (6)
This species will often circle its prey before moving in to attack it.
Blue sharks primarily feed upon relatively small prey, such as bony fish
and squid, but will also take larger prey including mammalian carrion (1)
"The Blue shark is one of the fastest swimming sharks, and can easily
keep up the pace with most fish species. The body is long, sleek and
perfect for fast swimming since the water resistance becomes very
small. The large caudal fin moves side-to-side and provides plenty of
power to the Blue shark. It swims in a graceful manner and is strong
enough to make leaps out of the water. More research is needed to
confirm the maximum speed of the Blue shark. Some scientists estimate
the maximum speed to be roughly 35 km/h (22 miles per hour), while
others claim that the maximum speed can be as much as 97 km/h (60 miles
per hour). "
